Abstract
The invention relates to the field of new material research and development. The invention discloses a micro-nano particle deposition device. The device comprises an injection pump, an infusion tube,cover glass, a protective layer, a micro-fluidic layer, a suspension bridge, a substrate, a displacement table and a microscope. The micro-fluid layer comprises a micro-pore diameter, a micro-channelgroup, a main channel and a liquid inlet. A microfluid structure is adopted and based on capillary action. Particle self-assembly is carried out by forming a suspension bridge containing particles tobe deposited between a micro-pore diameter and a movable substrate. The suspension liquid is supplied by adopting a specially designed microfluid structure, the suspension liquid can be continuously supplemented and the components of the suspended particles can be adjusted in the assembling process, the components of the suspended particles can be adjusted and the suspension liquid can be continuously supplemented in the particle self-assembling process, the operation is simple and convenient, and the cost is low.
Description
technical field [0001] The invention relates to the field of research and development of new materials, in particular to a micro-nano particle deposition device using a microfluidic structure and based on capillary action. Background technique [0002] Particle assembly based on capillary action is a bottom-up (bottom-up) particle self-assembly process technology, which uses a substrate with an ordered microstructure on the surface and a cover glass on top of the substrate, and confining a droplet of suspension containing particles to be deposited between the substrate and the cover glass, and then causing the cover glass to move slowly relative to the substrate to form an arcuate area close to the surface of the substrate, and then With the evaporation of water in the suspension, the concentration of the particles to be deposited in the arc surface area increases, and a part of the deposited particles are deposited on the substrate and assembled in an orderly manner. Defec...
