▎ 摘　　要

NOVELTY - The method involves introducing gas into a micro-fluidic chip to replace an injection of a liquid-fluidic chip, and forming a micro-reaction cavity in the micro-fluidic liquid in a form of a gas-coated type. Microparticles are provided with cells, cell clusters, microorganisms, microbial clusters, bacteriophages, exosome, micelles and artificial microspheres, where the artificial microsphere is provided with polyethylene glycol, polyacrylamide, polymethyl acrylic acid, polymethyl acrylate, polyvinyl alcohol, polyethylene, polystyrene, polyester, silicon dioxide and graphene microsphere. USE - Method for utilizing a micro-fluidic chip of a kit (all claimed). ADVANTAGE - The method is easy to operate, low in cost and strong in commonality. The method enables realizing quick exchange of fluid, high-efficiency separation of single particle and capturing. The method enables obtaining particle with high purity, avoiding chip blocking and realizing recycling and utilizing convenience. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a method for acquiring detection data; and (2) a computer program product comprising a set of instructions for acquiring detection data. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of a micro-fluidic chip.
