Bioimaging by Two-Photon Absorbing Chromophores and Nanoparticles
Jin Sun Park, Jin-Kyung Park, Prem Prabhakaran and Kwang-Sup Lee
In this contribution we present an overview of two-photon sensitized bioimaging in the perspective of the materials. This review is primarily meant to be used by a chemist to gain an overview of the scope and challenges of this rapidly growing field of science. We look at the spectrum of two-photon active organic, organic-inorganic hybrid materials that have been studied for this application. Two-photon imaging is being used extensively in the study of cancerous cells. In this context we have also looked at different strategies of material design for targeting cancer cells.
