摘要

A simple electrochemical immunosensor for determination of Streptococcus suis serotype 2 (SS2) is presented. Nickel hexacyanoferrate nanoparticles (NiHCFNPs) and gold nanocages (AuNCs) were combined together through complexation between the cyanide (CN-) and gold ions, and acted as a carrier for immobilization of the detection antibody (Ab2). The capture antibody (Ab1) was combined by a protein A (PA) and gold nanoparticle (AuNP) modified electrode. In a sandwich-type immunoassay mode, ascorbic acid (AA) was added to the base solution and its oxidation was catalyzed by the AuNCs-NiHCFNPs complex to greatly amplify the response signal. The resulting immunosensor exhibited excellent selectivity and sensitivity, with a linear concentration range of 0.0005-80 ng mL(-1) and a detection limit of 0.15 pg mL(-1).
