Abstract

The invention relates to a micro-nano particle movement control method based on a data-driven ODEP kinematic model. The invention includes: making an ODEP chip, injecting a liquid sample with micro-nano particles; obtaining identified micro-nano particle information; drawing an optical pattern; The horizontal and vertical coordinate data information of the corresponding optical pattern; the horizontal and vertical coordinates of the optical pattern are used as the input, and the horizontal and vertical coordinates of the manipulated target micro-nano particles are used as the output to establish a model; Nanoparticle manipulation. The invention avoids the assumption conditions and the force simplification process of the existing method based on the calculation expression of ODEP force for operating micro-nano particles, and only needs to give a control input according to the established model, and then the corresponding control output can be obtained. The precision of ODEP technology to manipulate micro-nano particles.

Description

technical field [0001] The invention relates to the technical field of micro-nano operation and micro-nano device precision manufacturing, in particular to a micro-nano particle movement control method based on a data-driven ODEP kinematic model. Background technique [0002] Micro-nanoparticles can be widely used in the preparation of semiconductor materials and new materials, biotechnology research, medical industry and other fields. The essence of the application of micro-nano particles is to manipulate them through micro-nano technology to obtain target products, and the technology of manipulating micro-nano particles directly affects the quality and efficiency of products. [0003] Optically Induced Dielectrophoresis (ODEP) technology can be used to manipulate micro-nanoparticles. Its core is a chip based on a "sandwich" structure, which consists of two upper and lower layers of glass with indium tin oxide (ITO) on one side. , and a layer of hydrogenated amorphous sili...
