Preparation of Molecular Surface Imprinting Material and Its Identification Properties for Bilirubin
表面印迹法制备胆红素分子印迹材料及其识别性能

Polyethyleneimine(PEI) was grafted onto the surface of silica gel particles via the coupling effect of 3-methacryloxypropyl trimethoxysilane(MPS),and the grafted particle PEI/SiO2 was prepared.Then,the molecular imprint polyethyleneimine on the surface of silica gel,MIP-PEI/SiO2,was prepared with bilirubin as a template molecule and ethylene glycol diglycidyl ether(EGDE) as crosslinking agent by using novel molecular surface imprinting technique.Both static and dynamic methods were adopted to study the iden...
