Schematic representation of sandwich type nanoparticle-based immunoarray fabricated on 2 separate microwells with different capture antibodies for different target biomarker detection. Schematic shows preparation of multi-nanoparticles trace tag, and detection strategy by linear-sweep stripping voltammetric analysis of AgNPs on the immunosensor surface without acid dissolution.
