ABSTRACT:
A detection apparatus for detecting the presence of a sample, the detection apparatus comprising a chamber, ports for introducing a sample within the chamber, an actuation unit for establishing a controllable electromagnetic field in the chamber; and a sensing unit for sensing changes in the electromagnetic field due to the presence of the sample within the chamber. The sensing unit comprises a sensor device comprising a source and a drain embedded in a FET a gate for the FET, in which the gate is formed of a material whose conductivity is related to the electromagnetic field established in a nonconductive medium in contact with the gate.
