Ultrasensitive electrochemical biosensor based on reduced graphene oxide-tetraethylene pentamine-BMIMPF6 hybrids for the detection of α2,6-sialylated glycans in human serum.
本文报道了一种基于还原氧化石墨烯-四乙烯五胺-1-丁基-3-甲基咪唑六氟磷酸盐(rGO-TEPA-BMIMPF6)杂化材料的简单、超灵敏、无标记电化学生物传感器,用于检测人血清中的α2,6-唾液酸化糖链。rGO-TEPA富含氨基,BMIMPF6通过静电作用使双金属金铂合金纳米粒子(AuPtNPs)密集吸附于纳米复合材料表面,形成大表...
