l-Cysteine induced hemin/G-quadruplex concatemers electrocatalytic amplification with Pt–Pd supported on fullerene as a nanocarrier for sensing the spore wall protein of Nosema bombycis

Abstract

This work described a pseudobienzyme electrocatalytically amplified immunosensor for sensing the spore wall protein of Nosema bombycis by adopting L-cysteine as the electrocatalytic substance to generate H₂O₂in situ with the aid of hemin/G-quadruplex concatemers loaded onto C₆₀@Pt–Pd. The hemin/G-quadruplex here is also acting as the probe for electrochemical signal output.
