What is a silver nanoparticle (AgNP)?

Silver nanoparticles (AgNPs) (1–100 nm in size) are another type of metallic colloidal NP commonly used in manufacturing, biomedicine, and engineering. The inhaled ultrafine AgNPs can pass through the blood–lung barrier and enter the circulatory system.

What are silver nanoparticles used for?

Introduction Silver nanoparticles (AgNPs) are increasingly used in various fields, including medical, food, health care, consumer, and industrial purposes, due to their unique physical and chemical properties. These include optical, electrical, and thermal, high electrical conductivity, and biological properties [ 1, 2, 3 ].

Can silver nanoparticles be used in biomedical fields?

Drug Discov Today. 2015 May; 20 (5): 595–601. Silver nanoparticles (AgNPs) have been widely used in biomedical fields because of their intrinsic therapeutic properties. Here, we introduce methods of synthesizing AgNPs and discuss their physicochemical, localized surface plasmon resonance (LSPR) and toxicity properties.

Why are silver nanoparticles gaining attention?

It is gaining attention due to its cost effective, ecofriendly and large scale production possibilities. Silver nanoparticles (AgNPs) are one of the most vital and fascinating nanomaterials among several metallic nanoparticles that are involved in biomedical applications.

What are silver nanoparticles?

Silver nanoparticles are nanoparticles of silver of between 1 nm and 100 nm in size. While frequently described as being 'silver' some are composed of a large percentage of silver oxide due to their large ratio of surface to bulk silver atoms. Numerous shapes of nanoparticles can be constructed depending on the application at hand.

Can silver nanoparticles be used in biomedicine?

Theranostics. 2020; 10 (20): 8996–9031. Silver nanoparticles (AgNPs) have been one of the most attractive nanomaterials in biomedicine due to their unique physicochemical properties. In this paper, we review the state-of-the-art advances of AgNPs in the synthesis methods, medical applications and biosafety of AgNPs.

What is silver nanoparticles synthesis?

Silver nanoparticles synthesis: top-down approach and bottom-up approach, i.e. physical synthesis method, chemical and biological synthesis methods, separately.
