Biosensors

Overview

Development of novel biosensor platforms for rapid and sensitive detection of biomarkers, pathogens, and environmental contaminants.

Our biosensor research focuses on creating innovative detection platforms that combine biological recognition elements with physical transducers to achieve highly sensitive and selective measurements. We develop sensors for applications ranging from clinical diagnostics to environmental monitoring and food safety.
