“…The diffraction pattern of supported nanoparticles showed peaks at 2θ of 38.08°, 44.27°, 64.38°, 77.34° and 81.43°. These observed peaks were assigned to face-centered cubic (fcc) crystal structure of metallic Ag nanoparticles (ICDD card no 00-004-0783) corresponding to (111), (200), (220), (311) and (222) planes [ 24 ]. These observations confirm the reduction of Ag + to the metallic form.…”

“…Compared with physiochemical methods, biosynthesis methods have advantages such as low cost, eco-friendly and easy availability ( Olga et al, 2022 ). Many biological substances such as polysaccharides, polyphenols, proteins and extracts from plants or animal tissues are considered suitable capping agents and stabilizers ( Sivaramasamy et al, 2016 ; Kharissova et al, 2019 ; Jian et al, 2020 ; Dhar et al, 2021 ). The AVH-AgNPs used in the present study had been biosynthesized using abalone viscera hydrolysates obtained through primary enzymatic hydrolysis, and showed low toxicity, high dispersion stability and antimicrobial properties ( Zhang et al, 2022 ).…”

Silver nanoparticles (AgNPs) have the potential to be used in aquaculture, but their influence on the growth and health of aquatic organisms has not been extensively investigated. In this study, the abalone viscera hydrolysates decorated AgNPs (AVH-AgNPs) were dispersed into aquaculture water at different concentrations (0, 6, 9, and 18 μg/l) to evaluate the biological effects on zebrafish (Danio rerio). The results showed that the AVH-AgNPs treatments of 6 and 9 μg/l promoted the growth and did not cause obvious damage to the gills, intestines, and livers of zebrafish. All the treatments induced catalase (CAT) and superoxide dismutase (SOD) activities and increased glutathione (GSH) content in the livers and upregulated the expression of immune related genes. The effects of 9 and 18 μg/l AVH-AgNPs treatments were more obvious. After AVH-AgNPs treatment, the abundances of some potential pathogens, such as species Plesimonas shigelloides and Pseudomonas alcaligenes and genus Flavobacterium decreased significantly. In contrast, the abundance of some beneficial bacteria that can degrade pollutants and toxins (e.g., Rhodococcus erythropolis) increased significantly. Thus, the application of low concentrations (6 ~ 18 μg/l) of AVH-AgNPs in aquaculture water is relatively safe and has a positive effect on zebrafish farming.

“…P. emblica is a tropical fruit that is pervasively planted in the countries of Southeast Asia, such as China, India, Vietnam, and Thailand, where people have had the edible fruit over thousands of years. With considerable nutritional value and an abundance of tannins (33% of its dry weight), vitamins (especially vitamin C), amino acids, minerals, phenolic acid, and flavonoids, the fruit are fatigue-, oxidation-, and inflammation-resistant, and can prevent tumors and diabetes [ 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. Because of the presence of vitamin C and excellent oxidation resistance, P. emblica shows potential for melanin-confining and oxidation-resistant cosmetics.…”

PVP/CS/Phyllanthus emblica Nanofiber Membranes for Dry Facial Masks: Manufacturing Process and Evaluations

et al. 2022

In the wake of increasing demands on skin health, we propose simple, natural, and safe dry facial masks that restrict melanin synthesis. Phyllanthus emblica (P. emblica) is made into powders via a low-temperature extraction and freeze-drying process to serve as a natural agent. Next, it is added to mixtures containing Polyvinylpyrrolidone (PVP) and Chitosan (CS), after which the blends are electrospun into PVP/CS/P. emblica nanofiber membrane dry facial masks using the electrospinning technique. The dry facial masks are evaluated using the calibration analysis method, extraction rate test, scanning electron microscopy (SEM), release rate test, tyrosinase inhibition assay, biocompatibility test, and anti-inflammatory capacity test. Test results indicate that when the electrospinning mixture contains 29.0% P. emblica, the nanofibers have a diameter of ≤214.27 ± 74.51 nm and a water contact angle of 77.25 ± 2.21. P. emblica is completely released in twenty minutes, and the tyrosinase inhibition rate reaches 99.53 ± 0.45% and the cell activity ≥82.60 ± 1.30%. Moreover, the anti-inflammatory capacity test results suggest that dry facial masks confine inflammatory factors. PVP/CS/P. emblica nanofiber dry facial masks demonstrate excellent tyrosinase inhibition and are hydrophilic, biocompatible, and inflammation-free. The dry facial masks are a suitable material that is worthwhile exploring and applying to the cosmetic field.
