Nanoparticles that can deliver messenger RNA are a fascinating topic of interest currently due to the development of COVID vaccines. My lab is working on developing better drug delivery systems. Transcript: "I think the most fascinating topic that people are interested in now are nanoparticles that can deliver things like messenger RNA. And I mean, a great example of that are the COVID vaccines, that if it wasn't for the drug delivery systems, we wouldn't have those vaccines. And I think people are interested in making better and better ones over time. We're doing a lot of work on that in our lab ourselves."
