چکیده

Novel biomaterials based on hydrophilic polycaprolactone and polyurethane (Tecophilic®) nanofibers with an encapsulated 5,10,5,20-tetraphenylporphyrin photosensitizer were prepared by electrospinning. The doped nanofiber textiles efficiently photo-generate O(2)((1)Δ(g)), which oxidize external chemical and biological substrates/targets. Strong photo-virucidal effects toward non-enveloped polyomaviruses and enveloped baculoviruses were observed on the surface of these textiles. The photo-virucidal effect was confirmed by a decrease in virus infectivity. In contrast, no virucidal effect was detected in the absence of light and/or the encapsulated photosensitizer.

Photosensitized singlet oxygen and its applications

The study of singlet molecular oxygen production and reactivity has emerged as a rich and diverse area with implications in fields ranging from polymer science to cancer therapy. In this review, we address the photophysical properties of singlet oxygen and of the photosensitizers used in its generation. Photosensitizers based on organic molecules and coordination compounds are examined and comp...

Indirect EPR evidence for the production of singlet oxygen in the photosensitization of nucleic acid constituents by proflavine.

EPR spectroscopy is used to analyse the influence of D2O and NaN3 on the free radicals induced in frozen aqueous solutions of 5'-thymidine monophosphate photosensitized (lambda greater than 320 nm) by proflavine at 205 K. The results can be explained if the production of singlet oxygen during the process is assumed.

Singlet Oxygen Production Photosensitized by Fluorescein in Reversed Micellar Solutions

The quantum yield of singlet oxygen production was investigated in dodecylammonium propionate reversed micellar solutions containing 1,3-diphenylisobenzofuran and fluorescein as photosensitizer. The quantum yield was highly enhanced by the binding of fluorescein to reversed micelles, and increased with decreasing the solubilized water content in reversed micelles. Results obtained was discussed...

Subtle structural changes in octupolar merocyanine dyes influence the photosensitized production of singlet oxygen.

The photophysical properties of two indoline-based octupolar merocyanine dyes and of the corresponding quinoline-based dyes were examined. This seemingly subtle structural change in the chromophore of these molecules has an appreciable effect on the yields with which these respective compounds sensitize the production of singlet molecular oxygen, O2(a(1)Δg). The indoline-based dyes are reasonab...

Singlet oxygen emission at 1270 nm in protoporphyrin solution excited by argon laser.

The direct observation of dye-photosensitized 1270 nm emission of the 1 delta g leads to 3 sigma g transition of molecular oxygen in liquid solution is reported. Singlet oxygen was photosensitized by argon laser excitation of protoporphyrin in carbon tetrachloride.
