I am developing a bacterial biofilm Surface Acoustic Wave (SAW) sensor for in vivo real time biofilm growth monitoring. The motivation of the work is to design a sensor which monitors in in vivo bacterial biofilms, especially in artificial implant sites, using wireless and highly sensitive methods to alert patients to a developing infection. The SAW sensor detects a biofilm through the resonant frequency shift due to mass accumulation on the surface of the sensor. 

















           All of the sensor materials are biocompatible, and the operational frequency is designed to meet wireless medical device regulations set by the Federal Communication Commission. Current work includes sensor fabrication and characterization with in-vitro bacterial biofilm studies.
