A electrogenerated chemiluminescence biosensor for Ramos cancer cell using DNA encapsulated Ru(bpy)3Cl2 as signal probeBiosensors and Bioelectronics - Tập 26 - Trang 3887 - 2011
Hun Xu, Wang Wei, Chen Huaicheng
A label-free sensing technology for detection of Ramos cell was developed based on a signal probe Ru(bpy)3Cl2 (Ru) encapsulated by DNA. Gold electrode or magnetic bead as the sensing surface was firstly modified with long-strand DNA with five repeating units. Then two kinds of short-strand DNA are grafted onto the long-strand DNA to form DNA strands A and B (L-A and L-B) through the hybridization,...... hiện toàn bộ
