Classification and property of nanomaterials.

Classification	Name	Property
Inorganic nanomaterials	Selenium nanoparticles	With good water solubility and fast degradation
	Mesoporous silica	With adjustable aperture, which is easy for synthesis and modification
	Quantum dots	At low production cost, of small size, with photothermal response
Organic nanomaterials	Liposomes	With controlled particle size, membrane-alike structure, and low cytotoxicity
	Graphene oxide	It has a large number of modification sites, diverse functions and strong extensibility, good dispersion, strong stability, and it can extend the cycle time
	Metal-organic frame
