The recent emphasis on nanocarrier development for drug delivery stems from the need to target specific diseased areas while sparing healthy tissues. Effective and safe drug administration has long posed challenges in medicine. Over the past decade, the emergence of vesicles as a means to enhance drug delivery has captivated researchers in the field of drug delivery systems. Among vesicular systems, niosomes have gained attention due to their nonionic features. Unlike liposomes, niosomes offer superior stability, making them a preferred choice. Non-ionic in nature niosomes offer unique advantages in drug delivery providing a versatile platform for encapsulating various drugs to enhance bioavailability and ensure controlled release. Understanding preparation techniques enables tailored applications from oral to transdermal delivery. Characterization methods such as morphology and particles size are pivotal in ensuring the stability and effectiveness of niosomes. Applications span cancer therapy, diagnostic imaging, and vaccination adjuvants, showcasing niosomes versatility. Ongoing research reflects dynamic efforts to enhance capabilities, emphasizing their pivotal role in evolving drug delivery systems. In this comprehensive review, we aim to encapsulate fundamental aspects of niosomes, encompassing diverse preparation methods, various niosomal types, methods for characterization and the advancements witnessed in niosomal research over the past decade, drawing insights from a literature review.
