Fig. 1From: Complementation of ELISA and an Interdigitated Electrode Surface in Gold Nanoparticle Functionalization for Effective Detection of Human Blood Clotting Defectsa Schematic representation of the GNP-assisted ELISA. GNP was premixed with protein and immobilized on APTES-modified ELISA surface. Antibodies were then added. Finally, substrate for HRP was used to detect the target. b Schematic representation of the GNP-assisted IDEBack to article page
