in the present study, we have reported the biological synthesis of silver nanoparticles (agnps) using aqueous leaf extract prepared by hot percolation treatment of wheat varities (pbw343, triticum durum and aegilops tauschii )for the reduction of silver ions to silver nanoparticles. bioreduction of ag+ to ag0 was observed when aqueous extract augmented with silver nitrate (agno3) was incubated ...

Capping silver nanoparticles with LL37 peptide eradicates the antiproliferative effect of silver on primary skin cells, but retains the bactericidal properties of silver nanoparticles with activities comparable to silver nitrate or silver sulfadiazine. In addition, LL37 capped silver nanoparticles have anti-biofilm formation activity.

Silver nanoparticles were synthesized by an enzyme-induced growth process on solid substrates. In order to customize the enzymatically grown nanoparticles (EGNP) for analytical applications in biomolecular research, a detailed study was carried out concerning the time evolution of the formation of the silver nanoparticles, their morphology, and their chemical composition. Therefore, silver-nano...

BACKGROUND Antibiotic resistance is a global issue that threatens public health. The excessive use of antibiotics contributes to this problem as the genes of antibiotic resistance can be transferred between the bacteria in humans, animals and aquatic organisms. Metallic nanoparticles could serve as future substitutes for some conventional antibiotics because of their antimicrobial activity. The...

extracellular extract for the synthesis of silver nanoparticles using AgNO3. The formation of nanoparticles was confirmed by different methods, such as UV-Vis absorption spectroscopy, XRD, FTIR, EDX, and TEM analysis. The formation of silver nanoparticles (AgNPs) was confirmed by the change in color from light yellow to dark brown. The absorbance peak obtained at 430 nm confirmed the presence o...

the antimicrobial effect of metal nanoparticles such as zinc oxide and silver nanoparticles has been taken into great consideration separately during recent years. the useful application of these nanoparticles in the areas of medicine, biotechnology, and professional prevention of microbes motivated us. the aim of this study was to evaluate antibacterial activity properties of silver doped zinc...

background silver has been used from ancient times by humans, and recently nanoparticles of silver have been used in many aspects of human life including as a potent antibacterial agent. objectives in the current study a completely green method to prepare silver nanoparticles is reported. two types of starches (potato and corn starches) were used to produce and stabilize silver nanoparticles. a...

objective(s): this study was aimed at investigating the synergy effects of aloe vera gel and silver nanoparticles on the healing rate of the cutting wounds. materials and methods: in order to determine the concentration of silver nanoparticles in aloe vera gel, the mbc methods were applied on the most common bacteria infecting wounds, staphylococcus aureus, escherichia coli, pseudomonas aerugin...

A simple and inexpensive, single step synthesis of silver nanoparticles was achieved using sodium citrate both as a reducing and capping agent. Silver nanoparticles were synthesized by injecting sodium citrate solution into the solution of silver nitrate at high temperature. The synthetic process was carried out in aqueous solution, making the method versatile and ecofriendly. The synthesized s...
