The crystallization of lysozyme and ribonucleaseA was induced using photochemical reactions triggered by surface plasmon resonance of gold nanostructures. The tryptophan residues of the protein are radicalized by the enhanced electric field induced b

The photo-induced side effects of photodynamic therapy of cancer can be suppressed using pH-activatable porphyrin derivatives, which have been developed using an aniline moiety as a pH-responsive quencher. The acid dissociation coefficient of a pH-ac

The photochemical reaction of triplet benzophenone (3BP) induces the crystallization of hen egg-white lysozyme by producing a BP ketyl radical and a counter amino acid radical in lysozyme, resulting in lysozyme dimerization. Crystallization was induc

This work examined the mechanism involved in photoinduced crystallization of a lysozyme, focusing on the structure of the photoproducts that lead to crystal growth. It was determined that dimers formed via linking of tryptophan (Trp) residues are pre

To achieve highly selective tumor therapy and diagnosis, we have developed a novel low-pH-activatable photosensitizer, AI4P, which is a porphyrin derivative possessing four 5-diethylaminoindole units. These 5-diethylaminoindole units enhance internal
