Patent ID: 7214528

Claim:
A bioelectrical analyzer for identifying a biomolecular target comprising a protein or peptide, the analyzer comprising: a silicon substrate; a sample well formed on the substrate and structured to receive a fluid test sample; an electrode formed within the sample well of a metal having an exposed chromium surface to which proteins and peptides are directly adherent and the chromium surface having adherent thereto a biomolecular probe capable of complexing with a biomolecular target, the biomolecular probe comprising a protein or a peptide; a stimulator electrically coupled to the electrode and structured to provide an input signal spanning a selected frequency test range F 1 –F 2 within the frequency range; a detector operative to detect a signal of the fluid test sample over the selected frequency test range and generate a sample signal profile for at least one sample electrical parameter across the selected frequency test range; and means for comparing the sample signal profile with a first reference signal profile to detect a match across the selected frequency test range.
