Extending the lifetime of your food Minimizing the oxidation of lipids remains one of the most important challenges to extend the shelf-life of food products and reduce food waste. While most consumer products contain antioxidants, the most efficient strategy is to incorporate combinations of two or more compounds, boosting the total antioxidant capacity. Unfortunately, the reasons for observing these effects in food samples are still unclear, and it is common to observe very different responses even for similar mixtures. Aiming to address this problem, we have developed several artificial intelligence models to predict synergistic interactions of antioxidant molecules. Outcomes of […]

Efficient separations for complex samples Capillary electrophoresis (CE) is one of the simplest and fastest separation methods available today. In our lab, we are interested in developing analytical methodologies based on CE as well as the implementation of sample-pretreatment steps to improve the overall analysis. Aiming to further miniaturize the analysis, we are also interested in the the translational applications of microfluidics, the development of fabrication methods as well as the implementation of electrochemical methods for the detection at this scale. Recent papers Strategies for capillary electrophoresis: Method development and validation for pharmaceutical and biological applications Finja Krebs, Holger Zagst, […]

Simple and Efficient analytical tools Electrochemistry provides a simple, fast, and inexpensive way to quantify analytes at low concentrations and with tunable selectivity. Aiming to extend the applicability of ePADs, our group reported the possibility of implementing pyrolyzed paper as an active substrate for the development of detection electrodes. This material is produced via a simple manufacturing process and features competitive electrochemical activity, low cost, and the possibility to implement a wide variety of functionalization protocols. We are also interested in: Development and integration of respirometric assays, as a way to detect metabolically-active bacteria Wearable devices based on carbon electrodes […]
