Nanoparticle injection to single animal cells using femtosecond laser-induced impulsive force
- 145 Downloads
An impulsive force, which was generated by focusing tightly a femtosecond laser into a cell culture medium, was applied to inject nanoparticles into local areas of a single mouse fibroblast NIH3T3 cell. When the impulsive force was induced near the cell, the nanoparticles adhering on the cell membrane were introduced, which was directly confirmed by confocal fluorescence microscopy.
