These promising sensors are easily fabricated at relatively low cost, and could be mass-produced with commercial inkjetters. in sandwich immunoassays. A biotinylated secondary antibody with 16-18 horseradish peroxidase labels was used, and detection was achieved by hydroquinone-mediated amperometry. … Continue reading These promising sensors are easily fabricated at relatively low cost, and could be mass-produced with commercial inkjetters
