An electrochemiluminescence immunosensor for the N-terminal brain natriuretic peptide based on the high quenching ability of polydopamine.
报道了一种用于检测N端脑钠肽前体(NT-proBNP)的夹心型电化学发光(ECL)免疫传感器。该传感器以类石墨碳氮化物(g-C3N4)为发光体,聚多巴胺(PDA)为纳米猝灭剂。二维g-C3N4原位生长于二氧化钛纳米花(TiO2 NFs)表面,纳米花的宏观多孔结构提高了g-C3N4的界面稳定性,并促进其与共反应剂发生ECL反应。金纳米...
