What is it about?
We have shown that, at very high frequency (~ 200 MHz), capacitive biosensors can sense bacterial cells in physiological buffers.

Why is it important?
This work show the need of using very high frequency to increase the sensitivity and to co-integrate the sensor with CMOS technology.
