Abstract
The common medical polymer material to be used as cell culture substrate is treated through laser scanning to form micron/nanometer or submicon/nanometer channels before sterilization. Anchorage dependent cell in condition after trypsinization is inoculated homogeneously to the surface of the substrate for culture. Owing to the regulation and control of the surface channels, cell will grow and orient in the channel direction. The present invention has simple technological process and easy operation, and is suitable for the basic research in cell biology, making of biological sensor and functional device, research of medical implant, tissue engineering, etc.
