Indocyanine green as a prospective sensitizer for photodynamic therapy of melanomas.
Spectroscopic, photochemical and biological properties of indocyanine green (ICG) are presented. Light over 800 nm is effectively absorbed by ICG. This property as well as photochemical behaviour of ICG make it a very suitable dye for photodynamic treatment of melanoma cells. Cytotoxicity of ICG itself and the effect of photodynamic therapy (PDT) were evaluated by following the growth of human ...
متن کاملTritolylporphyrin dimer as a new potent hydrophobic sensitizer for photodynamic therapy of melanoma.
We report the synthesis, photochemical and photophysical properties and preliminary studies on biological effect of a new tritolylporphyrin dimer (T-D). Absorption and emission properties of T-D suggest its possible use in photodynamic therapy. T-D is capable of singlet oxygen production with 0.8 quantum yield. It also has a high photostability. The photodynamic properties of the dimer were exa...
متن کاملImidazole-modified porphyrin as a pH-responsive sensitizer for cancer photodynamic therapy.
5,10,15,20-Tetrakis(N-(2-(1H-imidazol-4-yl)ethyl)benzamide)porphyrin produced twice as many singlet oxygen ((1)O(2)) molecules at pH 5.0 (quantum yield 0.53 ± 0.01) than at pH 7.4, whereas the (1)O(2) quenching rate was reduced by a factor of 2.5 for a pH change from 7.4 to 5.0.
متن کاملBiosynthesis of Srco3 nanostructures with honey as a green capping agent and reductant: photodynamic therapy
Objective (s): SrCO3 nanoparticles could be used as new biomedical sources in magnetic resonance imaging as a promising noninvasive imaging modality for the preoperative staging of breast cancer and monitoring of tumor response to therapy. The present study aimed to synthesize SrCO3 nanostructures using microwave irradiation in the presence of honey as a green capping agent and reductant. Mater...
متن کاملSusceptibility of Candida albicans to photodynamic therapy using methylene blue and toluidine blue as photosensitizing dyes.
The increased resistance of Candida albicans to antibiotic therapy indicates the need for alternative treatments for oral candidiasis. Photodynamic therapy (PDT) has been researched as an alternative tool to inactivate pathogenic microorganisms. It uses a combination of a photosensitizer and a visible light source. This study evaluated the susceptibility of C. albicans to PDT and compared the e...
