Method for preparing magnetic/fluorescent/temperature-sensitive colloidal crystal microspheres through microfluidics and product thereof

The invention relates to a method for preparing magnetic/fluorescent/temperature-sensitive colloidal crystal microspheres by microfluidics and a product thereof, and belongs to the technical field of preparation of photonic crystal microspheres. According to the invention, magnetic/fluorescent/temperature-sensitive nanospheres prepared by soap-free emulsion polymerization are used as a dispersion phase, silicone oil is used as a continuous phase, and the magnetic/fluorescent/temperature-sensitive colloidal crystal microspheres are prepared by microfluidics. According to the preparation method disclosed by the invention, comonomers (Eu (AA) 3Phen and NIPAM) are introduced, so that the product is endowed with fluorescence property and temperature-sensitive property; meanwhile, the magnetic/fluorescent/temperature-sensitive nanospheres are taken as elements, and the magnetic/fluorescent/temperature-sensitive colloidal crystal microspheres are finally prepared by adopting a microfluidic droplet template technolog
