Abstract

In cell biology and regenerative medicine, there is a certain need to modify or manipulate cells, for example within the field of tissue engineering or gene therapy.

Laser radiation allows the precise manipulation and imaging of cells with subcellular resolution. However, high numerical aperture objectives have to be used, to achieve spatial localization and confinement of the laser radiation. Thereby, cell throughput is limited. A possible technology to achieve a similar confinement of laser radiation can be the employment of plasmonic resonances. Using noble metals so-called surface plasmons, being collective electron oscillations at the surface of nanostructures or nanoparticles, can be excited by the laser radiation. Within the near field of these plasmons, the high field intensities can be used to achieve manipulation or characterization of biological processes within a cell.
