Project goal: The main goal of the project is to develop a sensor platform based on graphitized textile amperometric electrodes for analyzing key metabolites (glucose and lactate) in human sweat during physical activity and training.

Project results: This project aims to develop fundamental and technological principles for the manufacture of sensor platforms based on graphene-based textiles for the analysis of clinically important molecules in human sweat. To achieve this goal, we propose to use unique samples of conductive fractionated graphene flakes as an electrode material for the manufacture of biocompatible amperometric textile electrodes. To make the electrodes sensitive and selective to target metabolites (glucose and lactate), the developed textile electrodes will be coated with appropriate oxido-reductases. Subsequently, the performance characteristics of the created textile electrodes will be tested in artificial sweat samples.
