Spectroscopic Characterization and Nanosafety of Ag-Modified Antibacterial Leather and Leatherette.

ABSTRACT: The development of antibacterial coatings is of great interest from both industry and the consumer's point of view. In this study, we characterized tanned leather and polyurethane leatherette, typically employed in the automotive and footwear industries, which were modified by photo-deposition of antibacterial silver nanoparticles (AgNPs). Material surface chemical composition was investigated in detail by X-ray photoelectron spectroscopy (XPS). The material's antibacterial capability was checked against Escherichia coli and Staphylococcus aureus, as representative microorganisms in cross transmissions. Due to the presence of silver in a nanostructured form, nanosafety issues were considered, as well. Ionic release in contact media, as well as whole nanoparticle release from treated materials, were quantitatively evaluated, thus providing specific information on potential product nanotoxicity, which was further investigated through cytocompatibility MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assays, also after surface abrasion of the materials. The proved negligible nanoparticle release, as well as the controlled release of antibacterial ions, shed light on the materials' potentialities, in terms of both high activity and safety.

Project description:Optical properties and fluorescence decay dynamics of a photoactive indole based antibacterial chromophore system, 2,3-distyrylindole (23DSI), were investigated using various spectroscopic characterization techniques. Experimental studies were done by utilizing steady-state UV-vis spectroscopy, steady-state fluorescence spectroscopy, time-resolved fluorescence upconversion spectroscopy, and time-correlated single-photon counting spectroscopy. Our studies show that the 23DSI molecule has a multiphoton absorption property as indicated by two- and three-photon absorption in the both the solution and the solid phases. The ultrafast time-resolved fluorescence upconversion studies show that this molecule undergoes a fast decay process with an average time constant of 34 ps, a single exponential decay, and an average fluorescence lifetime of 1 ns. The compound 23DSI did not show any signs of singlet oxygen production. The density functional theory (DFT) calculations showed that the 23DSI molecule has conjugated electron densities that are responsible for multiphoton absorption. The chlorine-substituted styryl groups, attached to the central indole ring facilitate the excellent electron delocalization within the molecule. This optimal electron delocalization, combined with the good electron conjugation in the 23DSI molecule is important for efficient multiphoton absorption and is in excellent agreement with experimental observations. Both the optical spectrum and emission spectrum using DFT calculations are also surprisingly well matched with the experimentally measured UV-vis spectrum and the emission spectrum, respectively. Combined experimental and theoretical studies suggest that excited electrons initially relax to the singlet state (S1) by internal conversion (IC) and subsequently relax back to their ground state by emitting absorbed energy as fluorescence emission. The outstanding multiphoton absorption capabilities of this 23DSI molecule support its potential application in both biological imaging and photodynamic inactivation (PDI).

Project description:This study bio-synthesized Ag@SeO2 bmNPs successfully, using turmeric ethanol extract, and characterized them using various techniques. The FT-IR analysis reveals the involvement of these plant-derived compounds, especially phenolics, in the reduction process by acting as electron donors and stabilizing/capping agents. Zeta potential analysis showed a slight negative surface charge for the stability of Ag@SeO2 NPs, where TEM revealed spherical nanoparticles with an average size of 20 nm. The XRD confirmed crystallinity and a core-shell structure, and EDX identified elements consistent with Ag@SeO2 and a 3 : 1 Ag/Se atomic ratio. Further, SEM supported the spherical shape and uniform size. These findings highlight the successful biosynthesis of Ag@SeO2 bmNPs with promising properties for diverse applications. Moreover, the Box-Behnken design (BBD) and artificial neural network (ANN) model were engaged to optimize Ag@SeO2 bmNP biosynthesis. BBD identified significant influences of pH, bioconversion temperature, time, and turmeric concentration on bmNP yield, with adjusted R2 and predictive R2 being 0.9075 and 0.8829, respectively. However, its limitations were revealed by a significant lack of fit. ANN modeling with a 3-5-7-1 topology showed superior predictive accuracy and identified optimal conditions for maximizing yield (pH 9.83, 51.7 °C, 1.0 h, 3.71 mg mL-1 turmeric). Validation experiments confirmed the model's reliability. Turmeric extract exhibited significantly higher amounts of phenolics, and flavonoids compared to the bmNPs, suggesting its potential for strong antioxidant activity. Both turmeric extract and bmNPs displayed antioxidant activity in ABTS and DPPH assays, with turmeric extract being the most potent due to its curcuminoid content. The potential activity of Ag@SeO2 bmNPs against S. aureus, K. pneumonia, E. coli, and B. cereus was investigated, with inhibition zones ranging from 22 to 32 mm. The MIC values of tested NPs towards pathogenic bacteria ranged from 165.625 and 331.25 μg mL-1.
