Optical trapping of porous silicon nanoparticles / M. G., D., M. A., M., Faggio, G., L., D.S., P. H., J., P. G., G., O. M., M.. - In: NANOTECHNOLOGY. - ISSN 0957-4484. - 22:50(2011), p. 505704.
Abstract:
Silicon nanoparticles obtained by ball-milling of a 50% porosity silicon layer have been
optically trapped when dispersed in a water–surfactant environment. We measured the optical
force constants using linearly and radially polarized trapping beams finding a reshaping of the
optical potential and an enhanced axial spring constant for the latter. These measurements open
perspectives for the control and handling of silicon nanoparticles as labeling agents in
biological analysis and fluorescence imaging techniques.
