Novel drug delivery systems (NDDS) delivered the active molecules to the target site in a defined manner for
produce the desired effects without disturbing the delicate bio-environment. Among many available colloidal drug delivery
systems, Liposomes (a class based on phospholipids) have attracted more attention than other systems due to many meritorious
features such as excellent chemical & biological stability, good solubilisation power, promote intracellular delivery
of bio-active molecules, reduce the uptake of macrophages and encapsulate both hydrophilic as well as lipophillic
drug molecule. In this review article, I try to give some basic knowledge about these carrier systems in tabular form,
which is more understandable concept as compared to simple text form.
