Silver nanoparticles AgNPs were synthesized using apple extract as a reducing agent and aqueous silver nitrate as the precursor. The AgNPs formation was observed as a color change of the mixture from colorless to dark-brownish. The X-ray diffraction pattern confirmed the presence of only Ag crystallites, and the dynamic light scattering estimates the average sizes of the AgNPs to be

Based on this, the extract of the plant was prepared and the synthesis of silver nanoparticles under different conditions were investigated. The best conditions for the synthesis of nanoparticles were 0. This is a preview of subscription content, access via your institution. Rent this article via DeepDyve. Gajjar, B. Pettee, D.

Nanoparticles of noble metals, especially the silver nanoparticles, have been widely used in different fields of science. Their unique properties, which can be incorporated into biosensor materials, composite fibers, cosmetic products, antimicrobial applications, conducting materials and electronic components, make them a very important subject to be studied by chemistry, biology, healthcare, electronic and other related branches. These unique properties depend upon size and shape of the silver nanoparticles. Different preparation methods have been reported for the synthesis of the silver nanoparticles, such as electron irradiation, laser ablation, chemical reduction, biological artificial methods, photochemical methods and microwave processing. This chapter aims to inform the synthesis methods of the silver nanoparticles. Silver Nanoparticles - Fabrication, Characterization and Applications. Silver has too much of modern industrial uses and is considered a store of wealth.

Silver nanoparticles NPs have been the subjects of researchers because of their unique properties e. A variety of preparation techniques have been reported for the synthesis of silver NPs; notable examples include, laser ablation, gamma irradiation, electron irradiation, chemical reduction, photochemical methods, microwave processing, and biological synthetic methods. This review presents an overview of silver nanoparticle preparation by physical, chemical, and biological synthesis. The aim of this review article is, therefore, to reflect on the current state and future prospects, especially the potentials and limitations of the above mentioned techniques for industries. Nanotechnology is an important field of modern research dealing with design, synthesis, and manipulation of particle structures ranging from approximately nm. Nanoparticles NPs have wide range of applications in areas such as health care, cosmetics, food and feed, environmental health, mechanics, optics, biomedical sciences, chemical industries, electronics, space industries, drug-gene delivery, energy science, optoelectronics, catalysis, single electron transistors, light emitters, nonlinear optical devices, and photo-electrochemical applications 1 , 2 , 3 , 4 , 5 , 6.

Green Synthesis of Silver Nanoparticles Using Apple Extract and Its Antibacterial Properties

Nanotechnology is a rapidly growing field due to its unique functionality and a wide range of applications. Nanomedicine explores the possibilities of applying the knowledge and tools of nanotechnology for the prevention, treatment, diagnosis and control of disease. The current paper reviews various types of physical, chemical and biological methods used in the production of silver nanoparticles. It also describes approaches employing silver nanoparticles as antimicrobial and antibiofilm agents, as antitumour agents, in dentistry and dental implants, as promoters of bone healing, in cardiovascular implants and as promoters of wound healing. The paper also explores the mechanism of action, synthesis methods and morphological characterisation of silver nanoparticles to examine their role in medical treatments and disease management.

Synthesis of Silver Nanoparticles

Беккер не шелохнулся. Что-то сказанное панком не давало ему покоя. Я прихожу сюда каждый вечер. А что, если этот парень способен ему помочь. - Прошу прощения, - сказал .

Колеса неистово вращались на рыхлой земле. Маломощный двигатель отчаянно выл, стараясь одолеть подъем. Беккер выжал из него все, что мог, и отчаянно боялся, что мотоцикл заглохнет в любую минуту. Нельзя было даже оглянуться: такси остановится в любой момент и снова начнется стрельба. Однако выстрелов не последовало. Мотоцикл каким-то чудом перевалил через гребень склона, и перед Беккером предстал центр города.

Беккер заморгал от неожиданности. Дело принимало дурной оборот. - Ты, часом, не шутишь? - Он был едва ли не на полметра выше этого панка и тяжелее килограммов на двадцать. - С чего это ты взял, что я шучу. Беккер промолчал.
