文摘

Triple signal amplification strategy was used to fabricate electrochemical immunoprobe. Bovine serum albumin-stabilized copper nanoclusters acted as redox species. Immunoprobe was constructed by co-immobilizing antibody and bovine serum albumin-stabilized copper nanoclusters on platinum nanoparticles.
