Application of chitosan/Fe₃O₄ microsphere-graphene composite modified carbon ionic liquid electrode for the electrochemical detection of the PCR product of soybean Lectin gene sequence.
本文以碳离子液体电极(CILE)为基底,构建壳聚糖(CTS)/四氧化三铁微球(Fe3O4)–石墨烯(GR)纳米复合修饰的电化学DNA生物传感器。单链DNA探针直接固定于CTS/Fe3O4–GR/CILE表面,在优化条件下与目标单链DNA杂交。以亚甲基蓝(MB)为电化学指示剂,通过差分脉冲伏安法测量MB还原峰电流研究杂交反应。Fe3O...
