Research Abstract

Novel functional photomolecule-protein nanocomposites using the laser ablation method have been established. The photochemical properties of their nanocomposites and photoinduced electron transfer have been investigated with the use of spectroscopic techniques such as laser-induced transient absorption and time-reolved fluorescence in detail.
