The aim of this in vitro study was to analyze the effect of a blue light (λ = 420 – 480 nm), a single-walled carbon nanotube -OH, and their combination on the viability (cytotoxic or enhancement) of the skin cancer A431 cell line after 24 hours of incubation periods. Cell culture is the process of removing cells from living tissues and growing them in a laboratory setting until they are ready to be tested using photodynamic therapy and nanoparticles, which is known as direct irradiation in vitro. Skin cell plates (A431 cell line) grown in culture medium supplemented with 10% fetal bovine serum (FBS) were irradiated with blue light, treated with the nanoparticle, and treated with the combination of them, and plates were incubated for 24 hours. In all the experiments, a crystal violet assay was used to determine the viability of the cells, and the intensity of color was measured by a plate reader. The cells were kept at 37°C. Blue light results showed a considerable decrease (p≤0.001) at 240 seconds after 24 hours of incubation time in viability percent; nanoparticle results showed a considerable decrease in the viability percent (p≤0.001) for all concentrations; the most effective concentration was 200 µg/ml; and the combination results showed a significant decrease in cell viability percent (p≤0.001) for all concentrations as compared with the control group. The single-walled carbon nanotube- OH with a concentration of 200 µg/ml produced the greatest results when combined with a light exposure period of 240 seconds.

Initial production of the titanium dioxide nanoparticles TiO2 used the hydrothermal process. The onion peels and chitosan peel extracts, which are made using the Bio-synthesize approach. By using (UV-Vis) properties, the structural characteristics of TiO2 and TiO2 with extract from onion peels and chitosan peels were studied, and find the absorption edge of TiO2 NPs, TiO2 + onion peels and TiO2 + chitosan peels is around 236 nm, 244 nm and 237.5 nm respectively. The pattern of TiO2 for a number of peaks suggested a tetragonal rutile phase, according to X-ray diffraction (XRD) research. Energy dispersive X-ray, (EDX) was done for TiO2 NPs, TiO2 + onion peels and TiO2 + chitosan peels. Field emission scanning electron microscopy (FE-SEM) shows that the diameters ranging of TiO2 NPs, TiO2 + onion peels and TiO2 + chitosan peels from (43.32 nm to 47.77 nm), (34.11 nm to 62.77 nm) and (32.22 nm to 35.11 nm) respectively. Studying was done on the effect of TiO2 & TiO2 with extracts nanoparticles on bacterial growth, a variation was observed in the effect of the TiO2 & TiO2 with extracts on the growth of bacteria.

Thin film technology has helped offer an understanding of the crystalline structure of substances, further to the characteristics of electronic transitions and how they are used effectively in different applications. This research focused on the effect of the process of annealing on the structural and optical characteristics of tin sulfide (SnS) thin films. The technique of thermal evaporation was used to synthesize the film samples under a vacuum of about 10–7 mbar. The coated SnS thin films were annealed at 200 °C and the structural and optical characteristics parameters, such as absorbance and transmittance, as well as optical bandgap and band-tail energies in the range )300–1150( nm, were discussed. Under the influence of the annealing process, the average crystal size changed from 14 nm to 11 nm. The energy gap value increased from 1.53 eV to 1.85 eV, while Urbach energy was seen to reduce from 0.913 eV for fabricated samples to be 0.824 eV after the annealing process.

Nanocomposite films based on polymeric blend poly(vinyl alcohol) (PVA)/poly (ethylene glycol) (PEG) with 10 wt.% PEG in PVA and Ni2O3 at five different wt.% like 3, 4.5, 6, 7.5 , and 9 were fabricated. The analysis of FTIR spectra confirms the presence of functional groups belonging to the polymer systems. The surface images denote a good distribution of Ni2O3 particles and form a network of paths charge transfer within the polymeric blend. Above 300 nm, the transmittance curves of all samples showed a tendency towards saturation, and the value for blended polymer film was ~ 88% in the Vis and NIR areas of the spectrum, but it decreases almost gradually with increasing the weight reaching ~66% at 9 wt.% Ni2O3, which makes it suitable for different applications, (e.g. packaging for storage drugs regardless of cost or for solar cell applications). Optical band gaps of allowed transitions decreased from 4.385 to 2.22 eV. The values of the refractive index showed small increases from 2.45 to 2.68 with the increasing concentration of nanoparticles from 3 to 9 wt.%, where an increase in polarizability values upon loading of Ni2O3 NPs. The highest optical conductivity values appear in the UV region particularly in optimum incorporating amount of Ni2O3 NPs (9 and 7.5 wt.%). Other features under examination were also seen to be affected by the nano additive. Change of electrical parameters such as dielectric constant, dielectric loss, and A.C electrical conductivity for PVA-PEG/Ni2O3 as a function of Ni2O3 concentrations and applied electric field frequency makes it suitable for application in capacitors, transistors, and electronic circuits.
