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 modified with Au nanoparticles
- Paper-based microfluidic devices (μPADs)
- Our lab is also interested in the development of sensors based on other transduction methods, including optical
