23 Jul Process for preparing protein micropattern on surface of PET (polyethylene glycol terephthalate) base material
Abstract
The invention relates to a process for preparing protein micropattern on the surface of a PET (polyethylene glycol terephthalate) base material, which includes steps of firstly, preparing metal silver micropattern on the surface of the PET base material, soaking the PET base materials with the metal silver micropattern into SHPEG water solution so that a silver-plated area adsorbs SHPEG repelling protein and a non-silver-plated area reserves the property of the base material adsorbing protein, and accordingly, preparing the protein micropattern on the PET base material, and controlling selective adsorption of protein on the surface of the PET base material. The protein micropattern on the surface of the PET base material can be applied to surface biological diagnosis and manufacture of biosensors and biomedical devices and the like and creates a certain foundation for research of tissue engineering. Meanwhile, the protein micropattern on the surface of the PET base material is simple in preparation process, easy in control of preparation steps, low in cost and fine in fidelity and has excellent repeatability.
