Bio-for-engineering : modeling of Bragg resonators.

In order to achieve in-vivo bio-lasing, there is a need for the design and study of an organic Bragg resonator. Notably, phospholipids are organic in nature, nontoxic and biocompatible with the living cells. In addition, they have the ability to self-assemble and encapsulate different aqueous sol...
