Schematic representations of fundamental steps for biosensor fabrication: a Antibody immobilization with a self-assembled monolayer (SAM) on sensor platform, b Capture of target cytokine with anti-IL-6 antibody, c Functionalization using polyclonal antibodies mixture and conjugated anti-fluorescein isothiocynate (anti-FITC) antibody loading with horseradish peroxide, and d Amperometric signal from enzymatic amplification cycle of substrate.
