ИСТИНА

We have developed a drug container based on porous silicon coated with temperature responsive polymer, which can preserve the loaded drug inside the pores below the critical temperature of the polymer. Silicon nanoparticles were heated efficiently with infrared radiation while radiofrequency electromagnetic radiation was used to heat up the ambient medium of the nanoparticles. The temperature rise resulted in polymer chain collapse, pore opening and triggered drug release as the critical temperature was exceeded.
