Abstract:

Sequential use of electrochemical etching and picosecond laser ablation in ethanol and liquid nitrogen allows fabrication of silicon particles with size smaller than 100 nm and high level of crystallinity. Fabricated ensembles of nanoparticles exhibit effective photoluminescence with emission peaks located within biotissue optical transparency window, thus being promising as contrasting agents for bioimaging.
