Structural and luminescence properties of silicon nanocrystals in colloidal solutions for bio applications
Original language description
Luminescent silicon nanoparticles are promising for biological and me-dical research as luminescent markers, for drug delivery or toxicity studies. For intracellular biological research, it is necessary to prepare water-based or isotonic colloidal solutions of na-noparticles which are stable and non-toxic. In this work, we compare structural and optical properties of silicon nanocrystals in colloidal solutions, obtained by two fundamentally different methods: A microplasma-based synthesis (a “bottom-up techni-que) and porous silicon prepared by electrochemical etching of a silicon wafer (a “top-down method). Low-pressure microwave plasma synthesis produces 5-8 nm large silicon nanocrystals while the porous siliconcontains clusters 60-70 nm in diameter, composed of nanometer-sized luminescent nanocrystals. We have attempted to stabilize the nanoparticles via modification of the their surface by methyl groups.n
