Dye-sensitized photosynthesis: Eosin Y (EY), a dye photosensitizer, works efficiently as a molecular photoelectrode by catalyzing the visible-light-driven electron-transfer reaction for efficient regeneration of NADH through a photosensitizer-electron relay dyad. Injection of the photosensitized electron resulted in highly accelerated regeneration of NADH, which can be used by glutamate dehydro...

Photodynamic therapy (PDT) exploits light interactions and photosensitizers to induce cytotoxic reactive oxygen species. Photodynamic diagnosis (PDD) uses the phenomenon of photosensitizer emitting fluorescence to distinguish some tumors from normal tissue. The standard photosensitizer used for PDD is 5-aminolevulinic acid (5-ALA), although it is not entirely satisfactory. We previously reporte...

Introduction: Cutaneous leishmaniasis (CL) is a widespread disease that is epidemic in Iran, too. Photodynamic therapy (PDT) is an attractive modality to treat cancer and hyper proliferative diseases based on the use of a photosensitizer in the presence of oxygen and proper wavelength of light. In consideration of lesion location, lack of systemic involvement and inefficiency of current treatme...

Although introduced for the treatment of maculopathies, photodynamic therapy (PDT) is now largely used in some eye cancers treatment. The selective tissue damage with PDT is achieved by sequestration of the photosensitizer in the target tissue and focal activation of the photosensitizer by low energy directed light. In this way, it is possible to achieve the destruction of the tumor tissue by s...

Objective. Photodynamic therapy has been expanded for use in endodontic treatment. The aim of this study was to investigate the antimicrobial effects of diode laser irradiation on endodontic pathogens in periapical lesions using an in vitro apical lesion model. Study Design. Enterococcus faecalis in 0.5% semisolid agar with a photosensitizer was injected into apical lesion area of in vitro apic...

The work is devoted to the investigation of new nanostructural photosensitizer based on phthalocyanine derivative – zinc octa-4,5-decylthio-octa-3,6-chlorophthalocyanine with absorption maximum at 730 nm. Active substance was solubilized in micellar form based on non-ionic Pluronic-like surfactant. Nanostructural properties of dispersions were studied by means of correlation laser spectrometry....

In this article, we report metal-enhanced singlet oxygen generation (ME(1)O2). We demonstrate a direct relationship between the singlet oxygen yield of a common photosensitizer (Rose Bengal) and the theoretical electric field enhancement or enhanced absorption of the photosensitizer in proximity to metallic nanoparticles. Using a series of photosensitizers, sandwiched between silver island film...
