During her doctoral studies, she focused on chromatography and mass spectrometry. Recently, she was awarded second place in the “Sanofi Prize for Pharmacy 2026” competition, which is awarded by the French Embassy in the Czech Republic for her dissertation – Steroid Analysis Using Modern Chromatographic and Mass Spectrometry Techniques: From Fundamental Studies to Targeted Bioanalytical Applications (supervisor: Lucie Nováková, Charles University).&nbsp;<h5>What makes this field particularly exciting or unique in your view?</h5>What I&nbsp;enjoy about analytical chemistry is that, to a&nbsp;certain extent, it is a&nbsp;kind of detective work. You are often looking for ways to “make the invisible visible”. In other words, extract the information you are interested in from a&nbsp;complex sample and then interpret it correctly. What also appeals to me about bioanalytical chemistry is its interdisciplinary nature. It brings together analytical chemistry, biochemistry, biology and medicine, which means that you need to be able not only to translate a&nbsp;biological or clinical question into a&nbsp;measurable analytical experiment, but also to place the resulting data back into a&nbsp;broader biological context. This combination of different perspectives is probably what I&nbsp;enjoy most about the field. At the same time, there is still plenty of room for fundamental research, ranging from studying analytical techniques themselves and improving them to developing new methodological approaches.<h5>How did you end up at the <a target="_blank" rel="noopener noreferrer" href="https://mbu.cas.cz/en/research/laboratory-of-antibiotic-resistance-and-microbial-metabolomics">Laboratory of Antibiotic Resistance and Microbial Metabolomics</a>, and what project are you currently working on?</h5>I came to the Institute of Microbiology through a&nbsp;joint project between Dr Zdeněk Kameník and Assoc. Prof. Jan Bobek from the First Faculty of Medicine, Charles University. For me, it was also an opportunity to move from targeted analysis and the study of chromatographic techniques towards untargeted metabolomics and new biological questions.In the project, we are trying to identify new biologically active compounds that would be effective, particularly against pathogenic fungi. As a&nbsp;potential source of such compounds, we study streptomycetes, bacteria known for their ability to produce a&nbsp;wide range of biologically active compounds, including many antibiotics that are currently in clinical use. We focus on less-explored host-associated streptomycetes, in which we had already observed antifungal activity in previous experiments. We are especially interested in strains active against Candida albicans whose activity cannot be explained by the presence of a&nbsp;known bioactive compound. These strains may represent an interesting source of novel compounds. We then integrate the results of untargeted metabolomic analyses with genomic analyses, which allows us to obtain a&nbsp;more comprehensive view of the biosynthetic potential of selected strains.<h5>You also took part in this year’s Vědafest, a&nbsp;science outreach event for the public. What was it like?</h5>I already had some experience with science outreach through events such as Researchers’ Night and the Science Fair at my previous institution, but this year’s Vědafest was still new to me in some ways. This time, I&nbsp;was presenting a&nbsp;field that I&nbsp;myself had entered only relatively recently. It was therefore more challenging to find the right analogies and explain the essence of the topic in a&nbsp;way that was simple, yet precise and scientifically accurate. At the same time, that was exactly what made it inspiring. It forces you to look at your own work from a&nbsp;different perspective. What I&nbsp;enjoyed most was the spontaneity and curiosity of the children, who often came up with questions that would never even occur to an adult.<h5>What are the biggest challenges you face on your scientific journey, and what helps you overcome them?</h5>One of the greatest, but at the same time most interesting, challenges is, in my view, the uncertainty that is inseparably linked to research. For a&nbsp;long time, you often do not know whether you have taken the right direction in addressing a&nbsp;particular question or whether you will ultimately manage to find that figurative final piece of the puzzle. At the same time, this uncertainty is precisely what makes science exciting for me.Another major challenge, particularly in interdisciplinary projects, is communication. It is important from the very formulation of a&nbsp;hypothesis and the planning of experiments through to the interpretation of results, including negative ones, and placing them in a&nbsp;broader context. To some extent, every field has its own language, and finding a&nbsp;common understanding is not always straightforward. Personally, I&nbsp;find it very helpful to be able to discuss problems with colleagues on an ongoing basis, whether individually or during regular laboratory seminars. One of the major strengths of our current group is its interdisciplinary nature, which allows me to look at the same problem from several different perspectives. It is also important for me not to lose my curiosity, because that is ultimately what leads us to ask further questions.<h5>What are your plans after completing your PhD?</h5>After finishing my PhD, I&nbsp;decided that I&nbsp;do not need to have everything that comes next precisely mapped out straight away. I&nbsp;would like to keep different options open for a&nbsp;while and continue building on my experience in analytical chemistry, while at the same time connecting it with other areas that have a&nbsp;biological or medical relevance. I&nbsp;believe that we can keep learning throughout our lives, so I&nbsp;am quite curious to see where the next stage of my journey will take me.Thank you for the interview!

Interview: What Drew Postdoc Taťána Gazárková to Analytical Chemistry

Scientists at CEITEC Brno University of Technology have developed microscopic robots that could one day accelerate beer production and simplify food quality control. The magnetically controlled biobots can actively mix liquids during fermentation, speed up the process, and separate themselves from the finished product once fermentation is complete. The results of the research, carried out by Professor Martin Pumera’s team, were published in the journal ACS Nano.“When people hear the word ‘robot’ today, they often imagine an electronic device. In reality, however, a robot can be any system capable of autonomously performing a specific task,” explains Martin Pumera of CEITEC Brno University of Technology.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_Mikroroboti_z_CEITEC_mohou_urychlit_vyrobu_piva_i_kontrolu_kvality_potravin_7d9ff82875.jpeg" alt="CEITEC BUT/Jakub Rozboud: CEITEC Microrobots Could Speed Up Beer Production and Food Quality Control: Martin Pumera in his lab at CEITEC BUT." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CEITEC_Mikroroboti_z_CEITEC_mohou_urychlit_vyrobu_piva_i_kontrolu_kvality_potravin_7d9ff82875.jpeg 235w," sizes="100vw" width="1600" height="1067">The research team created so-called biobots—biohybrid microrobotic capsules containing brewer’s yeast and magnetic nanoparticles. When the yeast produces carbon dioxide during fermentation, the resulting bubbles cause the biobots to move up and down through the liquid. This naturally mixes the contents of the vessel and makes fermentation more efficient. Compared with conventional static particles, the biobots can therefore accelerate chemical processes that are important in food production.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_Mikroroboti_z_CEITEC_mohou_urychlit_vyrobu_piva_i_kontrolu_kvality_potravin_4_af5fd4611f.jpg" alt="CEITEC BUT/Martin Pumera's archive: CEITEC Microrobots Could Speed Up Beer Production and Food Quality Control: Hematite microrobot (image for illustrative purposes)." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CEITEC_Mikroroboti_z_CEITEC_mohou_urychlit_vyrobu_piva_i_kontrolu_kvality_potravin_4_af5fd4611f.jpg 209w," sizes="100vw" width="1600" height="1192">Another major advantage of the technology is that the biobots can be easily separated from the finished beverage. Thanks to the magnetic particles they contain, they can be controlled with a magnetic field and removed once fermentation is complete, eliminating the need for additional filtration. The researchers also demonstrated that the biobots can be reused over several production cycles.“Unlike conventional static particles, microrobots actively move throughout the entire volume of the liquid, allowing them to cover a larger area and make the whole process more efficient. At the same time, they also facilitate the automation of production,” adds Martin Pumera. The team is currently discussing potential applications of the technology with a major European brewery.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_Mikroroboti_z_CEITEC_mohou_urychlit_vyrobu_piva_i_kontrolu_kvality_potravin_3_e8e5a3a55a.jpg" alt="CEITEC BUT/Martin Pumera's archive: CEITEC Microrobots Could Speed Up Beer Production and Food Quality Control: g-C₃N₄ microrobots (image for illustrative purposes)." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CEITEC_Mikroroboti_z_CEITEC_mohou_urychlit_vyrobu_piva_i_kontrolu_kvality_potravin_3_e8e5a3a55a.jpg 158w," sizes="100vw" width="1476" height="1460">Martin Pumera’s group has long been exploring the use of microrobots and advanced materials in the food industry. In the past, for example, the team developed a flexible sensor for smart packaging capable of detecting spoiled fish. The new biobots therefore represent another step towards more advanced methods of food quality and safety control.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CEITEC_Mikroroboti_z_CEITEC_mohou_urychlit_vyrobu_piva_i_kontrolu_kvality_potravin_2_75c7fed958.jpeg" alt="CEITEC BUT/ACS Nano: CEITEC Microrobots Could Speed Up Beer Production and Food Quality Control: ACS Nano - cover featuring article by Martin Pumera et al." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CEITEC_Mikroroboti_z_CEITEC_mohou_urychlit_vyrobu_piva_i_kontrolu_kvality_potravin_2_75c7fed958.jpeg 117w," sizes="100vw" width="1600" height="2128">

Thermo Scientific QuEChERS Sample Preparation Kits

QuEChERS is a versatile sample preparation method for analyzing pesticides, veterinary drugs, and other residues in various sample types before GC-MS or LC-MS analysis.

<div><div><div><h3>QuEChERS sample preparation—now easier, more convenient, and affordable</h3>QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe)is a sample preparation method that was initially developed in 2003 for analyzing veterinary drugs in food. The method was also tested for pesticide residue analysis in plant material with great success. In 2003, the detailed method was published in the journal AOAC International. Since then, the QuEChERS method has evolved into a sample preparation technique used on a variety of analytes in an expanding number of sample types before analysis by <a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/cz/en/home/industrial/mass-spectrometry/gas-chromatography-mass-spectrometry-gc-ms.html">GC-MS</a> or <a target="_blank" rel="noopener noreferrer" href="https://www.thermofisher.com/cz/en/home/industrial/mass-spectrometry/liquid-chromatography-mass-spectrometry-lc-ms.html">LC-MS</a>.Thermo Scientific QuEChERS kits contain pre-packaged, ready-weighed salts, sorbents, and buffers to streamline your workflow and minimize the potential for error. The kits are grouped according to your analytes of interest, sample matrix, and preferred QuEChERS method:<ul><li>Original 2003 Method</li><li>AOAC 2007.01 Method</li><li>EN 15662 Method</li><li>NY/T 1380-2007 Method</li></ul>Complete packages—including both extraction and clean-up kits—are available. Extraction-only and cleanup-only kits are also offered to suit your laboratory’s sample preparation needs. These pre-packaged kits save time and money, make QuEChERS procedures easier and more convenient, and ensure quality to yield reproducible results and excellent recoveries for a wide variety of analytes.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Scientific_Qu_E_Ch_ERS_Sample_Preparation_Kits_2_1e99f0c81b.jpg" alt="Thermo Scientific QuEChERS Sample Preparation Kits" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Scientific_Qu_E_Ch_ERS_Sample_Preparation_Kits_2_1e99f0c81b.jpg 217w," sizes="100vw" width="891" height="640"><h3>Typical QuEChERS workflow</h3><div><div><div><div><div>As shown in the workflow diagram below, the QuEChERS method has four basic steps:<ol><li>Homogenize sample (fruit or vegetable)</li><li>Extract analytes of interest from a sample using extraction salts (pesticide residues, veterinary drugs, and/or mycotoxins)</li><li>Clean-up the resulting supernatant using dispersive solid phase extraction (dSPE)</li><li>Analyze by GC-MS or LC-MS</li></ol><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Scientific_Qu_E_Ch_ERS_Sample_Preparation_Kits_496491ceff.jpeg" alt="Thermo Scientific QuEChERS Sample Preparation Kits" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Scientific_Qu_E_Ch_ERS_Sample_Preparation_Kits_496491ceff.jpeg 245w," sizes="100vw" width="1170" height="706"><div><h3>QuEChERS products</h3></div><div><h4>QuEChERS extraction kits for original 2003 method</h4></div><div>The original QuEChERS method (Anastassiades et al, 2003) was developed by Steven J. Lehotay and Michelangelo Anastassiades in 2003 for the determination of pesticide residues in fruits and vegetables. The original method was created to analyze non-base-sensitive compounds and uses a sodium chloride buffer to reduce polar interferences and enhance extraction. Buffering is an important part of the QuEChERS procedure because it allows for analysis of pesticides and other residues that display pH dependence in their recoveries, depending on the sample matrix. Three different extraction kits are available to support the original 2003 QuEChERS method.<h5>Chemicals used in the original 2003 method</h5></div><ul><li>Acetonitrile: Used to perform single-phase extraction (SPE) on a sample</li><li>Anhydrous MgSO₄: Induces phase separation between water content in sample and acetonitrile layer during liquid-liquid partitioning step; removes remaining water from sample during dispersive solid phase extraction (dSPE) step</li><li>NaCl: Induces phase separation between water content in sample and acetonitrile layer during liquid-liquid partitioning step; removes residual water from sample; reduces polar interference and enhances extraction</li><li>PSA: Primary secondary amine, used to remove polar matrix components, citric co-extractives, and free fatty acids, from sample during dispersive solid phase extraction (dSPE) step</li></ul><div><h4>QuEChERS extraction and clean-up kits for AOAC 2007.01 method</h4>The AOAC 2007.01 QuEChERS Method was developed by Steven J. Lehotay and his co-workers, who modified the original 2003 method to accommodate the use of acetate buffering at higher concentration for greater buffering strength. Buffering is an important part of the QuEChERS procedure because it allows for analysis of pesticides and other residues that display pH dependence in their recoveries, depending on the sample matrix. These extraction and clean-up products here support the AOAC 2007.01 method.<div><h5>Chemicals used in the AOAC 2007.01 method</h5><ul><li>Acetonitrile: Used to perform single-phase extraction on a sample</li><li>Anhydrous MgSO₄: Induces phase separation between water content in sample and acetonitrile layer during liquid-liquid partitioning step; removes remaining water from sample during dispersive solid phase extraction (dSPE) step</li><li>NaOAc: Buffers the sample to stabilize pH</li><li>PSA: Primary secondary amine, used to remove polar matrix components, citric co-extractives, and free fatty acids, from sample during dispersive solid phase extraction (dSPE) step</li><li>C18: Removes fats, sterols, and other non-polar interferences from sample</li><li>GCB: Graphitized carbon black, removes pigment (not recommended for use with planar pesticides)</li></ul><div><h4>QuEChERS extraction and clean-up kits for EN 15662 method</h4>The extraction and clean-up products here support the EN 15662 method. Widely used in Europe, the EN 15662 method was developed by Michelangelo Anastassiades and co-workers, who modified the original 2003 method to accommodate the use of citrate buffering at a relatively low buffering capacity. This variation uses a sodium chloride buffer to minimize polar interferences in addition to sodium citrate dihydrate and disodium citrate sesquihydrate buffers. Buffering is an important part of the QuEChERS procedure because it allows for analysis of pesticides and other residues that display pH dependence in their recoveries, depending on the sample matrix.<h5>Chemicals used in the EN 15662 method</h5><ul><li>Acetonitrile: Used to perform single-phase extraction on a sample</li><li>Anhydrous MgSO₄: Induces phase separation between water content in sample and acetonitrile layer during liquid-liquid partitioning step; removes remaining water from sample during dispersive solid phase extraction (dSPE) step</li><li>NaCl: Induces phase separation between water content in sample and acetonitrile layer during liquid-liquid partitioning step; removes residual water from sample</li><li>Trisodium Citrate: Buffers the sample to stabilize pH</li><li>Disodium Citrate Sesquihydrate: Buffers the sample to stabilize pH</li><li>PSA: Primary secondary amine, used to remove polar matrix components, citric co-extractives, and free fatty acids, from sample during dispersive solid phase extraction (dSPE) step</li><li>C18: Removes fats, sterols, and other non-polar interferences from sample</li><li>GCB: Graphitized carbon black, removes pigment (not recommended for use with planar pesticides)</li></ul><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Thermo_Scientific_Qu_E_Ch_ERS_Sample_Preparation_Kits_3_721562526f.jpg" alt="Thermo Scientific QuEChERS Sample Preparation Kits" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Thermo_Scientific_Qu_E_Ch_ERS_Sample_Preparation_Kits_3_721562526f.jpg 245w," sizes="100vw" width="1471" height="488"><div><h4>QuEChERS clean-up kit for NY/T 1380-2007 method</h4></div><div>The NY/T 1380-2007 method is recommended by China Ministry of Agriculture for the QuEChERS Method sample preparation of 51 specific pesticide residues in fruits and vegetables with analysis by GC-MS.<h5>Chemicals used in the NY/T 1380-2007 method</h5><ul><li>Anhydrous MgSO₄: Induces phase separation between water content in sample and acetonitrile layer during liquid-liquid partitioning step; removes remaining water from sample during dispersive solid phase extraction (dSPE) step</li><li>PSA: Primary secondary amine, used to remove polar matrix components, citric co-extractives, and free fatty acids, from sample during dSPE step</li><li>C18: Removes fats, sterols, and other non-polar interferences from sample</li></ul></div></div></div></div></div></div></div></div></div></div></div></div>
