Two-photon absorption is an emerging discipline with numerous biomedical applications. The development of novel dyes with two-photon excitation properties is expected to refine and expand implementation of this photophysical process.
Two-photon absorption is employed in various cell biology applications including microscopic bio-imaging and photo-activated drugs, photodynamic therapy and 3D microfabrication of biomedical devices. Apart from specifically tailored dyes responsive to two-photon excitation, two-photon absorption also requires the use of optimised optical sources and instrumentation.
