英文摘要: The project intends to focus on wound healing and scar repair research after the cell layer is wounded, break through the current limitations in technology and methods to study healing and repairing,carry out the design and control of surface properties and structure based on the biochip,open up prospective applications of wound healing and anti-scarring after cell layer is wound in drug screening and the related fields. Based on the mechanism of healing and scar repairing in the organism, biochip used as the platform,the channel surface properties and structure used as the core, the micro/nano multi-level structures on the biochip are modified by use of physical processing or chemical modification,and the surfec properties are controlled by combining the physical with chemical surface modification techniques and methods, then the cell layer is cultured into biochip, the laminar flow phenomenon unique in the microchannel is used to injure cell layer to form a wound, study of wound healing and scar repairing,establish wound healing and scar repairing model,and selcet new drugs.The important points in the project focus on functional interface, micro/nano structures, regulation of cell growth; regulation of micro/nano structure and performance of surface,cell wound healing model,scar repairing model, effects of mul
