Porous silicon nanoparticles are promising for the development of innovative methods of cancer therapy due to their proven properties of biocompatibility and biodegradability. Nanoparticles can accumulate in tumor tissues in passive mode by being attached with receptors that are specific for certain tumors. We report aqueous suspensions of porous silicon nanoparticles as sonosensitizers of hyperthermia and cavitation effects under ultrasound radiation of therapeutic frequencies and intensities.
