英文摘要： Bio-adsorption forming is a new machining method to do the adsorption, handling, and arrangementoperation of the micro-particles by using microorganism with biological material and structure adsorption effect. By this way, it could achieve the complex structure forming based on the function of micro-particles and nano-particles, meet the demand of theoretical calculations research and efficient manufacturing of micro-nano devices and functional devices. In this project, the diatom with the complex micro-and nano-pore structure and the surface effect has been used as a research tool. Based on the reserach of the adsorption charecteristics of the different functional particles, biological particles adsorbed tool with excellent selective adsorption and desorption characteristics is been manufactured by the way of reasonable arrangement, connection, modification constructed of the diatom. It is a great scientific and technological challenge to the functional particles controllable and efficient arrangement forming by direct adsorption or external forces assisted adsorption. The goal of this project is initially established bio-adsorption forming process and theoretical system. By improving feature detection and characterization mathod the different physical and chemical properties of the diatoms, functionalized pa
