Liposomes vs. Niosomes: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 16, 2024
Liposomes are microscopic vesicles made of lipid bilayers, used for drug delivery; niosomes are similar vesicles made of non-ionic surfactants, offering stability advantages.

Key Differences

Liposomes are tiny spherical vesicles created from cholesterol and natural non-toxic phospholipids, used primarily in drug delivery systems. Niosomes are structurally similar to liposomes but are made from non-ionic surfactants, which can make them more stable.

The primary use of liposomes is to encapsulate drugs, enhancing the delivery of substances to target areas in the body. Niosomes serve a similar purpose but are often considered more stable and less prone to oxidation than liposomes.

Liposomes can merge with cell membranes, facilitating the transfer of their encapsulated materials into cells. Niosomes, with their unique composition, also effectively deliver contents but with potentially different interaction dynamics with cell membranes.

The stability of liposomes can be affected by environmental conditions like temperature and pH. Niosomes, on the other hand, offer greater stability across a range of environmental conditions due to their synthetic surfactant composition.

Liposomes are biocompatible and biodegradable, making them suitable for medical applications. Niosomes also share these characteristics but may offer extended shelf-life and enhanced control over the release of their contents.
