Hydrophilic luminescent silicon nanoparticles in steric colloidal solutions: their size, agglomeration and toxicity

Original language description

Luminescent silicon nanoparticles are promising for in-tracellular biological research as luminescent probe for in vitro and in vivo studies. We prepared nanoclusters of hydrophilic highly porous silicon by electrochemical etching. Colloidal suspensions of the nanoparticles in steric organics (bovine serum albumin (BSA), glutamic acid, dextran and glycine) were prepared to attempt to stabilize the nanoparticles and prevent their further agglomeration. The zeta potential indicates good stability for BSA and glycine solutions, while the zeta potentials of water, dextran and glutamic acid show that nanoparticles tend to agglomerate. Strong orange luminescence of nanoparticles is situated between 600 and 700 nm and remains stable in all used organic colloidal solutions. Performed study of in vitro toxicity revealed that sterically stabilized silicon nanoparticles are cytotoxic only at the highest used concentration (500 µg/ml) of the silicon nanoparticles in water and BSA.n
