Abstract
Biophotonics is a new multidisciplinary frontier which utilizes light–matter interactions for bioimaging, sensing diagnostics and light activated as well as optically tracked therapies. This article is focused on use of nonlinear optical processes for bio imaging as well as for light induced therapy. Examples illustrating recent achievements in these research fields are provided from our work at the Institute for Lasers, Photonics and Biophotonics. We present our progress in multimodal bioimaging using a combination of nonlinear optical phenomena such as two-photon induced fluorescence, coherent anti-Stokes Raman scattering (CARS), second harmonic generation and sum frequency generation. Synergy of the techniques employing these phenomena in a multimodal imaging approach enables chemically selective imaging and probing of the local macro molecular content in biological specimens. We also provide examples of two-photon induced fluorescence microscopy and two-photon induced therapy using specially designed molecules and nanoparticles.
