Highly sensitive IRS based biosensor for the determination of cytochrome c as a cancer marker by using nanoporous anodic alumina modified with trypsin.
检测人血清中细胞色素c(Cyt C)是评估癌症的常规医学检测。本文构建了基于干涉反射光谱(IRS)的生物传感器用于检测 Cyt C。首先制备纳米孔阳极氧化铝(NAA),随后用3-氨基丙基三甲氧基硅烷对 NAA 孔壁进行功能化得到 NAA-NH2,再将胰蛋白酶(Tryp)固定于 NAA 孔壁。该 IRS 传感器检测 Cyt C 的原理...
