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">

ARC Polyarc System

A Breakthrough Innovation Revolutionizing GC/FID Technology. The Polyarc System is transforming the way scientists use gas chromatographs with Flame Ionization Detectors.

The Polyarc system has a catalytic microreactor that enhances new and existing gas chromatographs (GCs) with flame ionization detectors (FIDs) by converting all organic compounds to methane molecules prior to their detection by the FID. In doing so, the Polyarc system reduces the need to perform time-consuming calibrations by creating a uniform detector response for truly universal carbon detection.
The Polyarc system gives scientists the capability to determine purity, quantify unknowns, qualify products, investigate, improve development and more in a simple, fast and more economical way that is transforming the industry.

</blockquote>
<h3>What is Polyarc?</h3>
The Polyarc is the next evolution of flame ionization detection (FID). The Polyarc converts the FID into a truly universal carbon detector using proprietary catalytic reactions that convert organic molecules to methane immediately prior to detection.
<h3>Why is it important?</h3>
The FID has two main challenges: lack of uniform response and low response to certain compounds. The Polyarc enhances your FID to solve these challenges by giving your FID a uniform response to nearly all organic molecules. The result is more accurate data, improved productivity, lab efficiencies, and the ability to detect more compounds.
<h3>How Does the Polyarc® System Work to Simplify and Improve GC/FID Quantification?</h3>
The Polyarc system has a catalytic microreactor that enhances GC/FIDs by converting all organic compounds to methane molecules prior to detection by the FID. The result?
A universal response for ALL organic molecules.

<h3>The Polyarc System Features an Optimized Design and Seamless Integration</h3>
The Polyarc system is the first commercial technology of its kind. The device uses proprietary technologies including novel catalysts, a specially designed 3D-printed micro reactor, and fast seamless integration into existing equipment.
The optimized internal design and catalyst microstructure maintains separation performance and peak shape while increasing sensitivity and enabling accurate quantification without calibration standards.

<h3>Perform Cutting-Edge Chromatography on Any Organic Compound with a Polyarc® System</h3>
Realize a greater breadth of analysis with improved detection of compounds previously invisible or with an extremely low sensitivity by gas chromatography using FID only — while reducing the need for time intensive calibration.
The careful selection and robust catalyst design enables the analysis of a wide variety of compounds including a range of heteroatoms, compounds of various sizes, and samples containing common catalytic poisons (e.g., S).

<h3>How Does the Polyarc System Compare to a Methanizer?</h3>
A conventional methanizer converts CO and CO₂ to methane, allowing low level FID detection of CO and CO₂. The significant advantage of the Polyarc system is that it converts all compounds to methane, allowing not only for the detection of CO and CO₂ , but also millions of other organic compounds.

ARC Jetanizer (Methanizer)

The Jetanizer is the easiest and most robust methanizer.

<h3>What is Jetanizer™?</h3>
The Jetanizer is the easiest and most robust methanizer. A methanizer is a chemical reactor that converts carbon dioxide and carbon monoxide to methane to enable sensitive detection by a flame ionization detector (FID) from &lt;20 ppb to 100%!
<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/ARC_Analyza_CO_2_od_1ppm_do_100_s_pouzitim_GC_jetanizeru_FID_9c922be2e9/ARC-Analyza-CO2-od-1ppm-do-100percent-s-pouzitim-GC-jetanizeru-FID.jpg" alt="ARC: CO₂ analysis from 1ppm to 100% with GC/Jetanizer/FID"/>
<h3>Why is it important?</h3>
<h4>Low-level detection of CO and CO₂ is important in:</h4>
<ul>
<li>catalysis </li>
<li>hydrogen (H₂) purity analysis </li>
<li>dissolved gas analysis (DGA)</li>
<li>greenhouse gas (GHG) analysis, </li>
<li>transformer oil gas analysis (TOGA)</li>
<li>ethylene/propylene monomers analysis </li>
<li>safe entry analysis, and more</li>
</ul>
Traditionally, large nickel-catalyst-filled tube methanizers are used, however, they are prone to frequent failures, and they are difficult and time consuming to operate and maintain. 
<blockquote>
Legacy nickel catalyst methanizers take 2-6 hours to install and replace. Jetanizers take &lt;5 minutes.
</blockquote>
ARC’s Jetanizer solves these challenges by improving response, robustness and ease of installation, by incorporating state-of-the-art catalysts into an FID jet. Moreover, the Jetanizer enables low level &lt;1 ppm formaldehyde analysis by GC avoiding the pitfalls of HPLC analysis of formaldehyde.
<blockquote>

</blockquote>
<h3>Benefits over Traditional Methanizers</h3>
<ul>
<li>Lower up-front cost</li>
<li>No extra plumbing: minimize fittings and leaks</li>
<li>No extra heater or controller: utilizes heat from FID</li>
<li>FAST installation: Less than 5 minutes</li>

<h3>Why should I use GCxGC?</h3>
The separation of compounds by gas chromatography is typically performed using a single analytical column. As samples become more complex, it can become difficult to separate all the compounds from each other and they can start to overlap, or co-elute. Longer or narrower columns can be used to increase resolving power, but with diminishing returns.
Comprehensive two-dimensional GC, or GCxGC, drastically increases separation power by adding a second analytical column after the first column. A modulator placed between the two columns pulses the analytes from the first column onto the second column. When the columns are orthogonal in separation power, this technique can result in an order of magnitude increase in the number of analytes that can be detected.
ARC’s solution takes advantage of stop-flow modulation to make GCxGC an attainable configuration for any analytical laboratory. It involves continually sampling the effluent from the first column into an accumulator tube and re-injecting it onto a second, smaller column with orthogonal separation. This second separation happens in the time it takes to accumulate the next sample. The pulse time is known as the modulation time.
