The created nanoparticles have a diameter of 200 nanometers and can be used to destroy cancer cells by heating them to high temperatures. The main advantage of the new method is that such nanoparticles successfully penetrate the tumor tissue, making it possible to use it in the human body.
Physicists have developed a method to produce hybrid nanoparticles composed of silicon and gold that absorb infrared radiation and release heat. This approach makes it possible not only to fight tumors, but also to create various sensors and optoelectronic devices, the press service noted.
Previous research has already shown that silicon nanoparticles with similar properties can be effective, but their sizes are difficult to control. Russian scientists managed to solve this problem using special porous silicon layers and laser radiation.
