ABSTRACT
Over the past several years, treatment of infectious diseases and immunization has undergone aparadigm shift. Stemming from the nanobiotechnology research, not only a large number of diseasespecificbiologicals have been developed, but also enormous efforts have been made to effectivelydeliver these biologicals. Non-ionic surfactant vesicles (or niosomes) are now widely studied asalternates to liposomes. Different novel approaches used for delivering these drugs include liposomes,Microspheres, nanotechnology, micro emulsions, antibody-loaded drug delivery, magneticMicrocapsules, implantable pumps and niosomes. Niosomes and liposomes are equiactive In drugdelivery potential and both increase drug efficacy as compared with that of free Drug. Niosomes arepreferred over liposomes because the former exhibit high chemical Stability and economy. Niosomes areself assembled vesicles composed primarily of synthetic surfactants and cholesterol. They are analogousin structure to the more widely studied liposomes formed from biologically derived phospholipids.Niosomes represent an emerging class of novel vesicular systems. Niosome formation requires thepresence of a particular class of amphiphile and aqueous solvent. In recent years a comprehensiveresearch carried over niosome as a drug carrier. Various drugs are enlisted and tried in niosomesurfactant vesicles. Niosome appears to be a Well preferred drug delivery system over liposome asniosome being stable and economic. Also niosomes have great drug delivery potential for targeteddelivery of anti-cancer, Anti-infective agents. Drug delivery potential of niosome can enhance by usingnovel Concepts like proniosomes, discomes and aspasome. Niosomes also serve better aid in diagnosticimaging and as a vaccine adjuvant.
