FORMING METHOD OF SURFACE OF SYNTHESISED NANOPARTICLES Russian patent published in 2009 - IPC B22F9/24 B82B3/00 

FIELD: nanotechnology.

SUBSTANCE: invention relates to nanotechnology and can be used for effective change of physicochemical properties of formed on nanoparticles surface inorganic nature of ligand envelope. For receiving of nanoparticles solution with ligand envelope into solution of metal salt in water or organic vehicle is successively introduced stabiliser solution, consisting ligands, and solution of reducer. After it is changed charge sign of ligand envelope by means of one-sided diffusion of substance molecules, changing charge sign of ligand envelope through the semipermeable membrane, into solution of nanoparticles. Additionally it is used membrane, allowing pores size less than size of nanoparticles, but more than size of substance molecules, changing charge sign of ligand envelope. In the capacity of stabiliser it is used substance, molecules' size of which less than size of semipermeable membrane pores.

EFFECT: it is provided receiving of nanoparticles with ligand envelope with specified properties.
