We have developed a highly sensitive chemical sensor using nanocoaxial electrodes with porous annuli and capacitive detection. In Zhao et al. "Ultrasensitive chemical detection using a nanocoax sensor", we report sub-ppb (parts per billion) sensitivity to various volatile organic compounds in nitrogen. Read more here.

We are developing nanocoax-based biosensor using a number of sensing modalities. In one (above), target molecule-specific linkers are functionalized on an inner surface of a hollow annulus nanocoax. Upon exposure to the target molecule (e.g. in serum, blood, saliva, etc.), this linker immobilizes the target via highly specific binding, with detection via capacitance/impedance spectroscopy.
