“…Furthermore, the phenolic content in the leaves of Pucuk Idat has been proven to be used as a bioreduction in synthesising silver nanoparticles [14]. Some plants that have been used to synthesize silver nanoparticles are Tristaniopsis merguensis [15], Dilenia indica [16], Jatropha curcas [17], and tiger grass (Lantana camara L.) [18].…”

In this study, green synthesis of silver nanoparticles via Cratoxylum glaucum leaf extracts loaded with polyvinyl alcohol and its bacterial activity were tested. Nanosilver from ‘Pucuk Idat’ leaves has a non-uniform size and tends to agglomerate, making the nanoparticle size unstable and challenging to apply further. Therefore, so that nanoparticles do not aggregate, efforts are made to add stabilizers. Polyvinyl alcohol (PVA) is a polymer that can be used as a stabilizer because it can prevent unwanted aggregation and oxidation processes. UV-Vis analysis results show that PVA as a stabilizer can avoid an increase in wavelength shift. Based on the results of this XRD analysis, it can be concluded that in this research sample, the silver nanoparticle is formed with a cubic crystal system, and it can be observed that the smallest average particle size is in the 0.75% Ag/PVA sample of 10.32 nm. Furthermore, based on the antibacterial test against E. coli and S. aureus, it can be explained that the 0.75% PVA-modified nanosilver sample showed weak to medium antibacterial activity..

“…However, it is necessary to add other compounds as antibacterial to support hydroxyapatite to be of maximum benefit, such as silver nanoparticles (nano silver). Nano silver has antimicrobial properties so it is applied in the medical field as wound dressings, cotton fibers, and antiseptic mixtures to inhibit bacterial growth as well as an air sterilizer [8]. Synthesis of nano silver was carried out by various methods, namely physical, chemical, and biological methods.…”

Dental caries is a disease caused by the bacteria Streptococcus mutans and Lactobacillus, and affects everyone regardless of age. One way to overcome dental caries is to clean the teeth with a toothpaste made from hydroxyapatite-nano silver-clove extract. Hydroxyapatite is a biomaterial that has biocompatibility, bioactivity, and osteoconductive so that it can remineralize teeth. Nano silver is an antibacterial component that is able to kill microorganisms that cause dental caries. The addition of clove extract as an antimicrobial and aromatic compound can increase the attractiveness of the product. This study aims to determine the physical and chemical characteristics of the hydroxyapatite-nano silver-clove extract gel formulation with varying concentrations of hydroxyapatite 1%, 2%, and 3%, and nano silver concentrations of 1 ppm, 5 ppm, and 10 ppm. The results of the homogeneity test, pH level, dispersion, and adhesion showed that the gel was in accordance with the test standard. The results of organoleptic tests and statistical analysis showed that variations in the concentration of hydroxyapatite and nano silver affected the color and aroma (P < 0.05), but did not affect the texture (P > 0.05) of the gel. FTIR spectrophotometric analysis showed that the formulation already contained OH, CO32-, PO43- groups derived from hydroxyapatite, C=O derived from nano silver, and OCH, CH3, C-C, =C-H derived from clove extract.

“…PVA is a polymer that is able to overcome the occurrence of agglomeration as a stabilizing agent. The occurrence of agglomeration is caused by the unstable sample used causing the particle size to become larger so that the resulting nanoparticles are unstable [3]. The addition of PVA to the synthesis of silver nanoparticles can affect the particle size.…”

Synthesis of silver nanoparticles using a bioreductant of simpur leaf extract to minimize the use of inorganic materials that are harmful and not environmentally friendly. Silver nanoparticles with the bioreduction method, the bioreductant solution was mixed with AgNO3 precursor and the addition of PVA concentrations was 0%, 0.75%, 1.5% and 3%. The purpose of this study was to determine the effect of PVA on the characteristics of silver nanoparticles on antibacterial activity. Analysis of functional groups in simpur leaf extract and Ag/PVA 0.75% using FTIR Spectrophotometer showed wave numbers 3443 cm-1 and 3441 cm-1 the presence of -OH groups and at wave numbers 1640 cm-1 and 1638 cm-1 the presence of C=O groups. UV-Vis analysis showed the optimum wavelength in the 3% PVA variation absorption region showed an absorbance value of 429 nm with an average size of 8.19 nm silver nanoparticles. Inhibition of silver nanoparticles against bacterial growth Escherichia coli and Staphylococcus aureus the highest concentration was at 100% with an inhibition zone diameter of 10.33 mm and 11.58 mm in the strong category.
