Lipid based nanocapsules: a multitude of biomedical applications

Lipid nanocapsules with their unique composition represent a promising biocompatible drug delivery platform in nanometer range with narrow size distribution. They are highly stable in comparison to other nano-vectors and were found to impart very desirable characteristics to the therapeutic molecule being delivered within. The current review sheds the light on the methods of preparation of lipid nanocapsules, which are simple and easily scalable, in addition to providing examples of post insertion of some compounds for prolonging vascular circulation, protection, and targeting several diseases. In addition, the review discusses the vast in vitro and in vivo applications of lipid nanocapsules when administered via different routes such as oral, parenteral and transdermal routes. Promising use of nanocapsules in treatment of cancer, Alzheimer's disease, dermatological conditions and other miscellaneous applications are highlighted.
