摘要
Graphene oxide (GO) was introduced in the process of systematic evolution of ligands by exponential enrichment (SELEX) to screen ofloxacin-specific single-stranded DNA aptamers. Four sequences with high homology, ap1, ap3, ap4 and ap5 were picked out. Their secondary structures were simulated, and the dissociation constants (K-d) were measured, which were 251.3, 130.1, 159.1 and 304.4 nM, respectively. The specificity of the aptamers was also evaluated.
