A Colorimetric Enzyme-Linked Immunosorbent Assay with CuO Nanoparticles as Signal Labels Based on the Growth of Gold Nanoparticles In Situ
A colorimetric immunoassay has been reported for prostate-specific antigen (PSA) detection with CuO nanoparticles (CuO NPs) as signal labels. The method is based on Cu(2+)-catalyzed oxidation of ascorbic acid (AA) by O(2) to depress the formation of colored gold nanoparticles (AuNPs). Specifically,...
