This invention relates to the technical field of nanomedical technologies, namely to the fabrication of nanocarriers of drugs for antitumor chemotherapy. The technical effects of the invention consistof increasing the efficiency of antitumor chemotherapy by increasing the activity of the cell absorption of nanocontainers loaded with an antitumor drug, avoiding of the nanocontainer toxicity for cells due to the use of dispersed boron nitride nanoparticles of 50-300 nm in diameter with a well-developed outer surface. The technical effects are achieved as follows. The method of boron nitride nanoparticles fabrication for antitumor drug delivery to tumor cells includes synthesis of spherical boron nitride nanoparticles of 50-300 nm in diameter with a well-developed outer surface by chemical vapor deposition using ammonia reaction gas, argon transport gas and powder mixture composed of amorphous boron and oxidizing reactants. Chemical deposition is carried out under the following conditions: 1000<=T<=1430, and 1.2<= Xi<=8, wherein T is the temperature of the powder mixture, the Xi is the ratio of the specific flows FAr / FNH3, the FAr is the specific flow of the transport gas and the FNH3 is the specific flow of the reactant gas. The ultrasonic treatment of BN nanoparticles agglomeration is realized followed by saturation of nanoparticles with antitumor drug by sorption and washing in distilled water.

The invention provides novel nanoscale delivery vehicles and composite nanoassemblies built from distinct nanoassembly units (e.g., block copolymer micelles and nanogels) with stoichiometric control. These intelligent composite nanoassemblies independently retain the key features of the nanoassembly units and greatly expand the potential functional features attainable based on the surface functionalization. The invention provides a novel approach to constructing nano-vehicles with controllable morphology based on combination of cooperative releasing mechanisms (e.g., redox sensitive nanogels and pH sensitive micelles). Two kinds of guests can be seperately and stably encapsulated in the composite nanocontainers, and then released sequentially under the stimulation of pH change and reduced glutathione.
