Porous silicon nanoparticles as scavengers of hazardous
· We report that silicon nanoparticles (SiNPs) with typical sizes from 5 to 50 nm prepared by grinding of porous silicon can act as efficient scavengers of human immunodeficiency virus (HIV) and respiratory syncytial virus (RSV). In vitro studies have revealed a strong suppression of the viral activity in the presence of SiNPs with concentration above 0.1 and 0.01 mg/mL for HIV and RSV
