Little Sensor Lab

Date Published: September 26, 2017

Judith Su's lab centers on label‐free single molecule detection using microtoroid optical resonators. The technique called FLOWER (Frequency Locked Optical Whispering Evanescent Resonator) uses frequency locking in combination with balanced detection and data processing techniques to achieve single molecule sensitivity and fast detection times.

The lab's main focus is on basic research, and translational medicine through the development of miniature field portable devices as a tool to detect, understand, control, and treat various diseases. The lab is also developing chemical sensors for environmental monitoring, reducing threats, assisting national defense, and enabling clean sport competition.
