Detection of biomolecules from nano to atto-gram through plasmonic Elisa via tuning the catalyst
A simple and affordable plasmonic ELISA platform is demonstrated using silver nanocrystals as chromogens, and nanocatalysts in the place of enzyme. Apart from ultralow detection limitup to 10 molecules of human Immunoglobulin G (2.5 × 10−18 g/1.68 × 10−19 M), we exhibit very broad dynamic range cove...
