Description
The organic interfacial compounds are required as highly stable linker between bioprobe and 2D nanomaterial such as graphene. During the fabrication process of nanobiosensor via micro electromechanical system (MEMS) process, the covalent stable functionalization on large-scale graphene and less toxic chemical to humans are needed. Although, π-π interaction-based interfacial chemical such as 1-pyrenebutyric acid n-hydroxysuccinimide ester (PANHS) was utilized as linker in previous researches, which has a limitation, low binding energy, high bandgap open, steric hindrance. Herein, by introducing oligo(phenylene ethynylene)amine (OPE), highly stable interaction and efficient immobilization were acquired. The novel surface treatment technology demonstrated the selective and sensitive detection performance under various environmental condition.
