摘要
The development of covalent organic framework nanosheet (COF NS) is becoming a vitally important research field by reason of its high permeability, ordered structure, high utilization of functional site, favourable dispersability and large aspect ratio, resulting in their widespread applications in separation, catalysis, sensing and optical device. In this work, a Tp-Bpy COF NS was prepared via an interfacial synthesis of 2,4,6-triformylphloroglucinol (Tp) and 5,5'-diamino-2,2'-bipyridine (Bpy), which has film morphology, high surface area, large pore, excellent stability and various functional site. It was utilized as a functional material to immobilize aptamers for constructing a sensitive electrochemical aptasensor. Compared with bulk Tp-Bpy COF, Tp-Bpy COF NS can significantly enhance the biosensing performance toward ultra-trace tobramycin. This work is benefit for the exploration of COF NSs and their electrochemical aptasensors in biosensing applications.
