Selenium nanoparticles (Se-NPs) has recently received great attention over owing to their superior optical properties and wide biol. and biomedical applications. Herein, crystallog. and dispersed spherical Se-NPs were green synthesized using endophytic fungal strain, Penicillium crustosum EP-1. The antimicrobial, anticancer, and catalytic activities of biosynthesized Se-NPs were investigated under dark and light (using Halogen tungsten lamp, 100 W, λ > 420 nm, and light intensity of 2.87 W m-2) conditions. The effect of Se-NPs was dose dependent and higher activities against Gram-pos. and Gram-neg. bacteria as well different Candida spp. were attained in the presence of light than obtained under dark conditions. Moreover, the viabilities of two cancer cells (T47D and HepG2) were highly decreased from 95.8 ± 2.9% and 93.4 ± 3.2% in dark than those of 84.8 ± 2.9% and 46.4 ± 3.3% under light-irradiation conditions, resp. Significant decreases in IC50 values of Se-NPs against T47D and HepG2 were obtained at 109.1 ± 3.8 and 70.4 ± 2.5μg mL-1, resp. in dark conditions than 19.7 ± 7.2 and 4.8 ± 4.2μg mL-1, resp. after exposure to light-irradiation The photoluminescence activity of Se-NPs revealed methylene blue degradation efficiency of 89.1 ± 2.1% after 210 min under UV-irradiation compared to 59.7 ± 0.2% and 68.1 ± 1.03% in dark and light conditions, resp. Moreover, superior stability and efficient MB degradation efficiency were successfully achieved for at least five cycles. In the experiment, the researchers used many compounds, for example, 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4Category: chlorides-buliding-blocks).
3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Category: chlorides-buliding-blocks
