Antibiotic resistance is a major threat to heath with the use of silver nanoparticles as possible approach; however, synthetic routes such nanomaterials are not environmentally friendly because chemicals required. In this work we approach both problems single solution that employs sunlight in visible spectrum prepare nanosilver on surface cotton fabrics soaked nitrate. Photoactivation leads act...

Silver salts and nanosilver (NS) are the common antimicrobial used in the treatment of chronic wounds, so they are important to assess their dermal toxicity. Therefore, in this study, the possible dermal toxicity of NS particles and silver nitrate (AgNO3), was tested by determining the serum level of transforming growth factor-β1(TGF-β1) and study on of mouse skin tissue. In this stu...

Sintering of nanosilver paste has been extensively studied as a lead-free die-attach solution for bonding semiconductor power chips, such as the power insulated gated bipolar transistor (IGBT). However, for the traditional method of bonding IGBT chips, an external pressure of a few MPa is reported necessary for the sintering time of ~1 h. In order to shorten the processing duration time, we dev...

Effects of heat-transferring property of silver nanoparticles were evaluated on two solid woods of poplar and fir and in combination with Borax. Nanosilver and Borax were applied in pressure vessel using Rueping method. The size range of silver nanoparticles was 20-80 nm. Specimens of 150×130×9 mm were prepared and five fire-retarding properties were measured using a newly designed slide fire t...

COVID-19 virus has spread almost all over the world, including Indonesia until now. in people with diabetes mellitus have a risk of exacerbating symptoms. Diabetes is disease caused by high blood sugar levels. Nanogold very strong anti-oxidant capability, while nanosilver anti-bacterial properties. In this research, nanogold-nanosilver was presented form health drinking water packaged 1 L bottl...

This article presents a proposed insight into the anti-viral potential of silver nanoparticles against novel coronavirus disease (COVID-19). Possible mechanisms influence on are considered. Models nanosilver complexes with spike protein amino acids were constructed using computer quantum-chemical modeling. The values electron density distribution, highest occupied molecular orbital, lowest unoc...

This paper describes a process of obtaining nanosilver and nanogold based on chemical reduction using substances contained in the aqueous extract of dog rose (Rosa canina). The resulting products were subjected to spectrophotometric analysis (UV-Vis), and testing of the nanoparticles' size and suspension stability was carried out by measuring the electrokinetic potential, ζ, via dynamic light s...
