"Hot Nanotechnology Papers 2012": Vesicular and Fibrillar Gels by Self-Assembly of Nanosized Oleanolic Acid

Title of the paper:  Vesicular and Fibrillar Gels by Self-Assembly of Nanosized Oleanolic Acid

Authors: Professor Braja Gopal Bag, Koushik Paul

University/Institute: Vidyasagar University


Gelling and encapsulation: Oleanolic acid (1) is a nanosized triterpenoid that self-assembles in different solvents to form nanosized vesicles. The vesicles formed can encapsulate fluorophores, including the well-known anitcancer drug doxorubicin, and 1 can also gelate many of the solvents tested. This strategy of gelation and encapsulation may be relevant to many other large triterpenoids.

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu
