Abstract
BACKGROUND With the increasing diffusion of tattooing, the photolability of tattoo inks has become a critical issue, as available data indicated that several tattoo colorants are unstable under sunlight, generating potentially toxic photodegradation products. Therefore, it is desirable to enhance the photostability of coloring agents contained in tattoo inks. AIMS Lipid microparticles (LMs) highly loaded with Acid Red 87 (C.I. 45380), a colorant used in tattoo inks, were evaluated for their effect on the colorant photoinstability. In addition, the capacity of the LMs to retain the incorporated C.I. 45380 colorant after their intradermal administration in excised porcine skin was investigated. METHODS LMs loaded with C.I. 45380 were prepared using glyceryl tristearate as the lipidic material and phosphatidylcholine as the surfactant. Non-encapsulated C.I. 45380 or the colorant-loaded LMs were irradiated with a solar simulator for photodecomposition studies or introduced in the excised porcine skin mounted in Franz diffusion cells for stability evaluation in the dermal tissue. RESULTS AND CONCLUSION The colorant content of the microparticles was 17.7%, and their size ranged from 25 to 170 μm. The light-induced degradation of C.I. 45380 was significantly decreased by its incorporation in the LMs from 20.2 ± 5.8% to 1.9 ± 2.1%. Moreover, after intradermal injection of free or microencapsulated C.I. 45380 in the excised pig skin, the LMs reduced by 93.7% (from 24.6 to 1.5%) the quantity of the colorant diffused and hence lost in the Franz cell receptor fluid. Hence, the LM carrier efficiently retained the entrapped C.I. 45380 following incubation in the dermal region of the isolated porcine skin, which is in favor of a long-lasting tattoo. Based on these data, the incorporation of C.I. 45380 in the LMs could represent a potentially useful strategy to reduce the photodecomposition of the tattoo colorant and its harmful interactions with the skin tissue.

Abstract
Tattoo colorants decompose under solar radiation and when exposed to laser light for their removal, leading to the accumulation in the dermis of toxic products. Aim of this study was to develop lipid microparticles (LMs) loaded with the colorant, Acid Red 87 (C.I. 45380) used in tattoo inks, and to investigate the effect of this system on the photostability of the colorant under simulated sunlight or laser irradiation. LMs loaded with C.I. 45380 were prepared by melt emulsification using tristearin and phosphatidylcholine as excipients. They were characterized by optical microscopy, laser diffraction, X-ray diffraction and release studies. Free C.I. 45380 and the colorant-loaded LMs were irradiated with a solar simulator or a Q-switched laser. Irradiation with a solar simulator demonstrated that photodecomposition of C.I. 45380 was markedly reduced by incorporation of the dye in the LMs, from 20.5 ± 4.6% to 1.3 ± 1.8%. Conversely, the laser-induced degradation of the colorant (30.1 ± 6.6%) was not significantly influenced by encapsulation in the LMs (the encapsulated C.I. 45380 loss was 27.4 ± 5.5%). Incorporation of C.I. 45380 in lipid microparticles enhances the photostability under sunlight of tattoo inks containing this colorant, without affecting its laser-induced degradation and hence laser removal efficiency.

Abstract
Emerging pollutants are an essential class of recalcitrant contaminants that are not eliminated from water after conventional treatment. Here, a photocatalytic microporous membrane based on polyvinylidene difluoride-co-trifluoroethylene (PVDF-TrFE) with immobilised TiO2 nanoparticles, prepared by solvent casting, was tested against representative emerging pollutants. The structure and composition of these polymeric membranes were characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy, Fourier-transform infrared spectroscopy, porosimetry, and contact angle goniometry. The nanocomposites exhibited a porous structure with a uniform distribution of TiO2 nanoparticles. The addition of TiO2 did not change the structure of the polymeric matrix; however, it increased the wettability of the nanocomposite. The nanocomposites degraded 99% of methylene blue (MB), 95% of ciprofloxacin (CIP), and 48% of ibuprofen (IBP). The microporous nanocomposite exhibited no photocatalytic efficiency loss after four use cycles, corresponding to 20 h of UV irradiation. The reusability of this system confirms the promising nature of polymer nanocomposites as the basis for cost-effective and scalable treatments of emerging pollutants.

Abstract
Nanostructured photoanodes were prepared via a novel combination of titanium dioxide (TiO2) nanoparticles and mesoporous carbon (C). Four different photoanodes were synthesized by sol–gel spin coating onto a glassy substrate of fluorine-doped tin oxide. The photocatalytic activities of TiO2, TiO2/C/TiO2, TiO2/C/C/TiO2, and TiO2/C/TiO2/C/TiO2 photoanodes were evaluated by exposing the synthesized photoanodes to UV–visible light. The photocurrent density observed in these photoanodes confirmed that an additional layer of mesoporous carbon could successfully increase the photocurrent density. The highest photocurrent density of ~1.022 mA cm−2 at 1 V/saturated calomel electrode was achieved with TiO2/C/C/TiO2 under an illumination intensity of 100 mW cm−2 from a solar simulator. The highest value of surface roughness was measured for a TiO2/C/C/TiO2 combination owing to the presence of two continuous layers of mesoporous carbon. The resulting films had a thickness ranging from 1.605 µm to 5.165 µm after the calcination process. The presence of double-layer mesoporous carbon resulted in a 20% increase in the photocurrent density compared with the TiO2/C/TiO2 combination when only a single mesoporous carbon layer was employed. The improved performance of these photoanodes can be attributed to the enhanced porosity and increased void space due to the presence of mesoporous carbon. For the first time, it has been demonstrated here that the photoelectrochemical performance of TiO2 can be improved by integrating several layers of mesoporous carbon. Comparison of the rate of removal of humic acid by the prepared photoanodes showed that the highest performance from TiO2/C/C/TiO2 was due to the highest photocurrent density generated. Therefore, this study showed that optimizing the sequence of mesoporous carbon layers can be a viable and inexpensive method for enhanced humic acid removal.
