Impedimetric aptasensing of the breast cancer biomarker HER2 using a glassy carbon electrode modified with gold nanoparticles in a composite consisting of electrochemically reduced graphene oxide and single-walled carbon nanotubes.
本文报道了一种用于电化学检测乳腺癌生物标志物HER2的阻抗法适配体传感器。以玻璃碳电极(GCE)为基底,先滴涂氧化石墨烯-单壁碳纳米管(GO-SWCNT)复合材料,再经电化学还原得到还原氧化石墨烯-单壁碳纳米管(ErGO-SWCNT)层,并在其表面电化学沉积金纳米颗粒(AuNPs)。随后将5'-巯基抗HER2 DNA适配体(APT)...
