Nano-kinetics of probe-particles in solution visualized by a pin-fiber video scope.

چکیده
The nano-kinetics of colloidal particles and living cells with the colloidal particles were visualized by a newly developed video scope. The system of the new video scope has a feature of fine controlling the illumination conditions by using a single optical fiber. This characteristic enables one to obtain clear images of living cells and the motions of colloidal particles by light-scattering effects. In the experiments, RBL-2H3 cells and gold colloidal particles were observed. Scattering images with high contrast and a dark background like in dark-field observations could be attained. In the experiments, a pulsed laser was also applied. The results obtained in this study could validate the effectiveness and possibility of a new video scope for applications to biological and biomedical fields.
