This research project improves previously developed point of care biosensing platforms, based on electrochemical methods, by means of developing microfluidic integrable whispering gallery modes (WGM) biosensors capable of achieving higher sensitivity and accuracy. This approach allows a better diagnosis of the endemic infectious diseases most expanded in Argentina such as Chagas, Dengue, Brucellosis, and Leptospirosis. The above-mentioned objective will be achieved by means of a collaboration between the research group to which I belong at the National Institute of Industrial Technology and the Vollmer Lab of Nanophotonics and Biosensing.
