 For me chemistry is fun, like you know you get to blow stuff up, you get things that change colors, you know you get stretchy things, you get slime, you know so and you know doing all those things is really, I think it's really fun and really enjoyable to do. In my lab we make nanoparticles, we're interested in particular inorganic solids as nanoparticles and the materials we make are based on silica so essentially it's glass micro beads, they're very small. We use them for some catalysis applications but we're also focused on drug delivery. So the nanoparticles that we make have a lot of internal surface area, they're really porous and that's good because we want to load them with things that we will then deliver say in a biological system and the surface area that they have is about a thousand meters squared per gram and that's 20% of the surface area of a football field. You have to really picture yourself on a football field and think about how big that really is and now take that amount of surface and picture compressing it down, crumpling it down like a piece of paper and then putting it inside a vial and this is what you would have really here. This is the same surface area as a football field, so 5000 meter squared per gram. It's a vehicle that you can put anything into which is kind of the exciting part, you can use it to treat any kind of cancer you want. You can put any antibody on the outside that you want, right? So to do all of that you first have to understand how to make that particle and that vehicle and that's what we're interested in my department.
