This flexibility allows for qualified and controlled release of therapeutics, enhancing their efficacy while reducing Unwanted effects. In addition, the surface area of niosomes can be modified to accomplish unique targeting of drugs to sought after internet sites in the human body, So enhancing therapeutic results and cutting down systemic toxicity. Overall, niosomes maintain terrific assure while in the pharmaceutical marketplace and proceed to get a topic of powerful exploration for his or her opportunity applications in several fields together with most cancers therapy, gene delivery, and vaccine growth.
Niosomes are nanosized vesicles composed of nonionic surfactants and cholesterol that sort when these compounds are dispersed within an aqueous medium. These lipid-based mostly buildings are much like liposomes but vary inside their composition, as niosomes use nonionic surfactants in place of phospholipids.
