COMPOSITE MATERIAL AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF

WIPO Patent Application WO/2021/109132

A1

The present invention provides a composite material. The composite material comprises nanoparticles and a flexible substrate, the nanoparticles comprise one or more of carbon nanotubes, graphene, gold nanoparticles, and polydopamine nanoparticles, the flexible substrate comprises one or more of thermosetting plastics such as polydimethylsiloxane and hydrogel, and the mass percentage of the nanoparticles in the composite material is 0-60‰. The composite material of the present invention is easy to prepare, has extremely strong light-to-heat conversion performance, and does not change the smooth surface of an original topological structure. Moreover, the composite material has universality and versatility for different cells, the delivery efficiency is close to 100%, and modified cells can be efficiently and non-destructively released and harvested by means of traditional trysinization, and the harvesting efficiency is more than 90%.
