Silicon nanoparticles of 1 to 5 nm size have received a great attention, as they combine size-dependent photoluminescence, the capacity for singlet oxygen generation and of reducing methyl viologen, and the richness of silicon surface chemistry. Remarkable properties of silicon based nanoparticles, when compared to other materials, are their biocompatibility, biodegradability and tunable surface derivatization for drug delivery and the fact that silicic acid administered to humans is efficiently excreted through the urine.
