Paper Abstract

ZnO nanoparticles are notoriously difficult to use as optical probes due to the energy required for excitation. Nonlinear properties give a way around the high energy necessary for excitation. By using second harmonic generation, SHG, and multiphoton excitation, MPE, it is possible to use NIR light to generate intense coherent light that does not lead to heating of the cell or noncoherent light that also leads to sudden heating of the cell and cell destruction.
