Who is Samir Mitragotri?

Samir Mitragotri is a Professor at University of California, Santa Barbara, an inventor and an entrepreneur. He is a researcher in the field of drug delivery and biomaterials.

Mitragotri’s key inventions include technologies that make it possible to deliver medicines into the body without using needles. Many modern medicines including vaccines and insulin are delivered by needles, which cause pain, non-compliance and infections arising from their misuse. Mitragotri has developed technologies to deliver such medicines through skin patches, topical gels or oral pills. Most vaccines and medicines cannot enter the body by simply rubbing onto the skin or swallowing because the skin and the gut are designed to serve as a barrier for entry. Mitragotri’s technologies are helping overcome this barrier. He developed ultrasound devices that can be placed on the skin to increase its porosity so that vaccines can enter the body and needle-free jet devices that can directly push the medicine into body. He also designed technologies to optimize topical formulations to safely deliver medicines into the body and invented a new class of peptides that can facilitate entry of medicines into skin cells. Collectively, Mitragotri’s inventions are making it possible to deliver medicines into the body in a painless way and offer a better alternative to needle injections for the treatment of various diseases including diabetes, infectious diseases and various dermatological conditions.
