In this study, silver-silica (Ag/SiO2) was synthesized using the sol-gel method by silica from rice husks. Silica derived from rice husk waste was previously synthesized using the sol gel method. In addition, the Ag material used in this study was also performed into silver nanoparticles (AgNPs). This method was chosen to obtain an Ag/SiO2 composite with nano size and high purity. AgNPs were synthesized using silver nitrate (AgNO3) by reduction method at 90 °C. The reducing agent and stabilizer used is trisodium citrate. UV-Vis, FTIR, XRD, and SEM-EDX were used for the analysis Ag/SiO2 composites. Uv-Vis analysis results Ag/SiO2 has an absorption peak at a wavelength of 412 nm with a bandgap energy of 2.25 eV. These peaks indicate that AgNPs have formed in the SiO2 membrane. The FTIR results revealed the Si-O-Si bonds which indicated the presence of silica and the Ag-O functional group, and the presence of AgNPs. The results of XRD analysis showed that the silica structure formed was cristobalite and silver crystals in the face center cubic (fcc) shape. The results of the SEM-EDX morphological analysis showed that the Ag/SiO2 nanocomposite was shaped like sharp stone chips and the presence of small granules (granules) with different particle sizes and shapes, slightly porous and the composition of the compounds in the Ag/SiO2 nanocomposite indicated the presence of various chemical elements in the sample, including carbon, oxygen, sodium, silica, and silver.

“…Saxena and Ayushi [29] have reported the fungicidal characteristics of AgNPs synthesized even from the plant pathogenic fugal strain S. sclerotiorum MTCC 8785 against the T. harzianum strain. Findings of Zamana et al [30] demonstrated that AgNPs were more effective antibacterials than conventional rifampicin as they obtained comparatively modest inhibition zones against gram-positive and gram-negative bacteria than those achieved by conventional rifampicin. Revathi et al [31] and Arsene et al [32] found that papaya's extracts are very effective reducing agents for the biogenic production of AgNPs; later, they further explained that AgNPs that are synthesized biologically using seed and root extract exhibit notable antibacterial as well as antibiofilm capabilities [32].…”

Metallic nanoparticles are very useful, effective, and usually synthesized by toxic and expensive chemicals. Silver nanoparticles (AgNPs), measuring less than 100 nm, have shown promising impact in several biomedical investigations. These can inhibit microbial growth and aid in medicine administration. Six substrates of Carica papaya were used to synthesize silver nanoparticles that can limit the growth of bacteria and fungi. In this article, we report the synthesis of AgNPs from the leaf, seed, callus, peel, fruit juice, and bark of Carica papaya. AgNPs synthesized from callus showed the most promising results when tested against the growth of bacteria like Xanthomonas campestris, Erwinia carotovera, Bacillus subtilis, and fungi (Aspergillus niger and Fusarium oxysporum) when compared with other extracts’ efficacy, and the callus was regenerated from petiole and midrib explants of Carica papaya in MS basal media supplemented with NAA and Kinetin (1 + 0.5 mg/L). A ratio of 1:20 of substrate extract to 1 mM AgNO3 produced the most effective nanoparticles in terms of capping, quality, and stability when tested through surface plasmon resonance (SPR) within the 400–435 nm range. The nanoparticle sizes of all six types were measured using Image J software on micrographs of SEM at 200 nm resolution. The average diameters were analyzed through Origin software, and the finest AgNPs were observed to be synthesized from callus extract, i.e., 18.91 nm with rod-like morphology. Energy dispersive X-ray (EDX) at 2.6 keV revealed 43.38, 75.39, 70.611, 36.54, 58.57, and 45.94 percent elemental silver in AgNPs formed from the leaf, callus, juice, seed, bark, and peel extract, respectively. Silver nanoparticles synthesized from callus extract were smaller and exhibited the most effective antimicrobial potential, with the highest inhibitory zone of 19 mm against Xanthomonas campestris bacterium and up to 14 mm against Aspergillus niger fungus. Furthermore, the percentage of elemental Ag (measured through EDX) was found to be highest in the nanoparticles synthesized from callus compared to those synthesized from the leaf, seed, peel, fruit juice, and bark of Carica papaya. Hence, the callus extract is the most suitable substrate for the reduction of silver nitrate solution in 1:20 to form the finest silver nanoparticles in an effective biogenic way.

“…Chemical reduction is the most frequently applied method for synthesizing silver nanoparticles as a stable colloidal dispersion in water or organic solvents [18]. In this nanosilver synthesis, sodium citrate is used as a reducing agent and stabilizer [19]. Research [20] said that synthesizing nanosilver using sodium citrate as a reducing agent and stabilizer will produce nanosilver particles with a spherical shape with particle sizes ranging from 30-60 nm.…”

Serum is one of the cosmetic products that people often use today. Along with the times and technological developments, innovations in serum products are also increasing with the addition of active ingredients. Nanosilver is one of the nanotechnology findings and is known as a good antifungal. In this study, serum products were made with the addition of nanosilver as an antifungal, with variations in the acquisition of 20 ppm nanosilver by 5, 10, and 15%. This study aims to determine the characteristics of nanosilver synthesized using UV-Vis Spectrophotometer and TEM, determine the physical and chemical characteristics of nanosilver serum preparations, and determine the antifungal activity of nanosilver in serum cosmetic preparations. In this study, the synthesis of nanosilver using a chemical reduction method with sodium citrate as a reducing agent and stabilizer. Characterization of nanosilver with UV-Vis Spectrophotometer showed that the synthesized nanosilver was relatively stable, and the results of description with TEM showed that the nanosilver produced was on the nanoscale with an average diameter of 35.075 nm and spherical shape. The physical and chemical characteristics of the serum preparation carried out by organoleptic testing showed that the five samples were homogeneous, non-irritating, and had a pH of 6. Testing of nanosilver antifungal activity was carried out by the DMC (Direct Microscopic Count) method with direct counting techniques under a microscope for eight weeks. Based on the calculation results, from week 0 to week 8, it shows that the serum preparation with the addition of nanosilver can inhibit fungi with the growth of the number of hyphae in F1, F2, F3, F4, F5 respectively 24.25; 22.25; 3.25; 3; and 2.75%.
