The synthesis that is described in this study is for the preparation of silver nanoparticles of sizes ranging from 10 nm to 30 nm with a defined shape (globular), confirmed by UV-vis, SEM, STEM and DLS analysis. This simple and favorable one-step modified Tollens reaction does not require any special equipment or other stabilizing or reducing agent except for a solution of purified mesquite gum...

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 ...

BACKGROUND The discovery of new solutions with antibacterial activity as efficient and safe alternatives to common preservatives (such as parabens) and to combat emerging infections and drug-resistant bacterial pathogens is highly expected in cosmetics and pharmaceutics. Colloidal silver nanoparticles (NPs) are attracting interest as novel effective antimicrobial agents for the prevention of se...

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...

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...

Chitosan–silver (CS–Ag) nanocomposite materials were synthesized by a simple chemical method. The synthesized CS–Ag nanocomposite contains 20 wt% silver. Silver nanoparticles were synthesized by chemical reduction method as well. The CS–Ag nanocomposite was characterized using Field emission scanning electronic microscope (FESEM), X-ray diffraction (XRD) and Fourier transform infrared spectrosc...

BACKGROUND Gum ghatti is a proteinaceous edible, exudate tree gum of India and is also used in traditional medicine. A facile and ecofriendly green method has been developed for the synthesis of silver nanoparticles from silver nitrate using gum ghatti (Anogeissus latifolia) as a reducing and stabilizing agent. The influence of concentration of gum and reaction time on the synthesis of nanopart...

Nanotechnology has been a recent developed field of science. Several methods were employed to synthesize different types of nanoparticles. In the present study, we demonstrate the synthesis of silver nanomaterials from leaf and fruit aqueous extracts of Morinda coreia Buck., Ham. using the biological method. The silver nanoparticles formation was confirmed by the colour change of the mixture an...
