摘要：
We applied the noise spectroscopy technique as a powerful tool for the investigation of nano-sized bio-objects. The electrical and noise properties of the fabricated liquid-gated Si nanowire field-effect transistors as well as the influence of biomolecule attachment events on the nanowire structure were studied. We revealed that the dimensionless Hooge parameter can be used as a figure of merit for the detection of biological objects in particular cardiac troponin I (cTnI).
