Název v původním jazyce

Stabilization of silicon nanoparticles in colloidal solutions

Popis výsledku v původním jazyce

Silicon nanoparticles, apart from their potential use in op-toelectronics or photovoltaics, are very promising also for biological applications. Typical requirements for such nanoparticles used in biological research are to prepare aqueous or isotonic (such as phosphate buffered saline - PBS) colloidal solutions of stable, uniform and strongly luminescing nanoparticles, with sizes suitable for the process of cell endocytosis, ideally in the range of tens to hundreds of nanometers.nWe have prepared colloidal solutions of luminescing porous silicon nanoparticles (size around 100 nm) obtained by electrochemical etching of silicon wafers. Adding hydrogen peroxide to the etching bath results in oxidized nanoparticle surface and hydrophilic behavior. However, the as-prepared samples agglomerate. The first attempt to steric stabilization by bovine serum albumin, glycine, glutamic acid and dextran is presented, where the increased stability was observed in the glycine- terminated samples.n
