The Sundaresan Laboratory

Measurement Science at the Single-entity Level

Group photo - Fall 2023.jpg

The Sundaresan lab employs electrochemical and optical techniques to 1) study the behavior of single entities such as nanoparticles, molecules, enzymes, and bacteria, and 2) develop ultra-sensitive chemical and bio-sensors.
