Nanosilver is a nanoparticle known for its good antifungal ability. This study aims to determine the synthesis process and characterization of nanosilver produced and the antifungal activity of nanosilver in body lotion preparations. Body lotion in this study was made using a body lotion base which includes stearic acid, cetyl alcohol, TEA, glycerin, olive oil and distilled water. F1, F2, and F3 have nanosilver content of 10%, 15% and 20%, respectively. F4, as the positive control, contained methylparaben and F5 as a negative control. The body lotion produced in this study has a colour, aroma and texture that panellists prefer. The body lotion produced does not irritate the skin, is homogeneous, has good spreadability and has a pH value of 7. Nanosilver in this study was synthesized using a chemical reduction method with sodium citrate as a reducer and stabilizer. The synthesized nanosilver was characterized using a Transmission electron Microscope (TEM) and UV-Vis spectrophotometer to determine the nanosilver’s shape, size and stability. The nanosilver produced has a round shape with an average particle diameter of 34.793 nm and has good stability because it has a wavelength absorption peak that is not large. Namely, at week-0, nanosilver has an absorption peak at a wavelength of 415.20 nm, and week-8 has an absorption peak at a wavelength of 423 nm. The antifungal activity test using the direct microscope count (DMC) method was conducted for eight weeks. Until week 8, it showed that each formulation experienced an increase in fungal hyphae, reaching 34.4% for F1, 21.2% for F2, 19.8% for F3, 16.8% for F4 and 46% for F5. From the results of this study, it can be seen that nanosilver can suppress fungal activity in body lotion preparations.

Biosynthetic metals have attracted global attention because of their safety, affordability, and environmental friendliness. As a consequence, the cell-free filtrate (CFF) of Dill leaf-derived endophytic fungus Aspergillus luchuensis was employed for the extracellularly synthesis silver nanoparticles (AgNPs). A reddish-brown color shift confirmed that AgNPs were successfully produced. The obtained AgNPs were characterized by UV–Vis (ultraviolet–visible spectroscopy), Transmission electron microscopy (TEM), FTIR, EDX, and zeta potential. Results demonstrated the creation of crystalline AgNPs with a spherical shape at 427.81 nm in the UV–Vis spectrum, and size ranged from 16 to 18 nm as observed by TEM. Additionally, the biogenic AgNPs had a promising antibacterial activity versus multidrug-resistant bacteria, notably, S. aureus, E. coli, and S. typhi. The highest growth reduction was recorded in the case of E. coli. Furthermore, the biosynthesized AgNPs demonstrated potent antifungal potential versus a variety of harmful fungi. The maximum growth inhibition was evaluated from A. brasinsilles, followed by C. albicans as compared to cell-free extract and AgNO3. In addition, data revealed that AgNPs possess powerful antioxidant activity, and their ability to scavenge radicals increased from 33.0 to 85.1% with an increment in their concentration from 3.9 to 1,000 μg/mL. Furthermore, data showed that AgNPs displayed high catalytic activity of safranin under light irradiation. The maximum decolorization percentage (100%) was observed after 6 h. Besides, the biosynthesized AgNPs showed high insecticidal potential against 3rd larval instar of Culex pipiens. Taken together, data suggested that endophytic fungus, A. luchuensis, is an attractive candidate as an environmentally sustainable and friendly fungal nanofactory.
