Vesicles prepared from self-assembly of hydrated non-ionic surfactants molecules are called niosomes. These types of vesicles were first reported in the cosmetic industries. Niosomes exhibit more chemical stability than liposomes (a phospholipids vesicle) as non-ionic surfactants are more stable than phospholipids. Non-ionic surfactants used in formation of niosomes are polyglyceryl alkyl ether, glucosyldialkyl ether, crown ether, polyoxyethylenealkyl ether, ester-linked surfactants, and steroid-linked surfactants and a spans, and tweens series. Niosomes preparation is affected by processes variables, nature of surfactants, and presence of membrane additives and nature of drug to be encapsulated. This review article presents an overview of theoretical concept of factors affecting niosome formation, techniques of noisome preparation, characterization of niosome, applications, limitations and market status of such delivery system.
Stable citrate-capped silver nanoparticles (AgNPs) were developed as a colorimetric sensing probe for selective detection of ampicillin in urine samples.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
