 So, in Chicago at Northwestern University, I work on regenerative medicine, and I work on the nanotechnology of regenerative medicine. Our group was a proponent of the use of nanotechnology in regenerative medicine starting about fifteen, sixteen years ago, during the early phases of nanotechnology. I was going to say that was towards the beginning of this. Yes, that was the beginning. So, can you explain to people what nanotechnology means? So, nanotechnology means designing matter, designing materials and devices with sizes that are on the scale of nanometers. And so, a nanometer is a dimension that is equivalent to taking a hair and dividing it about a hundred thousand times, a single hair strand. So, that's a very, very small dimension. So, that's one nanometer. And so, I work creating structures that have dimensions of ten nanometers, perhaps fifteen nanometers, chemically, molecularly designed to have function and regenerative medicine. So, for example, we can customize structures that will grow bone or will regenerate the spinal cord or will regenerate cartilage or muscle or blood vessels where they are needed. And so, it's a very exciting activity, very exciting research. This afternoon, I told the audience about three recent stories on our work. And one of them was a project of the last few years which was just published in a top journal in nanotechnology called Nature Nanotechnology. And it was about designing nanostructures that have sugar molecules on their surfaces. So, not the sugar that you eat or that you put in your coffee, but sugars in a very specific structure. And these sugar molecules on the surfaces of fiber-like nanostructures, they make bone grow like crazy in an unprecedented way. And the reason that they do that is because the presence of those sugar molecules on our structures mimics a biological process whereby proteins in biology that are specific to grow bone, they attach to sugar molecules. And this way, they are in the best position to signal cells to make bone. So we were able to imitate or to mimic this natural environment in our nanostructures using our nanotechnology. And we actually tested this in vivo and it worked. And we're very excited about now translating this into the clinic. So when you say translate to the clinic, what would that look like for somebody that's coming in the door? What would you use this for? Well, for example, right here in Vail, you have the famous Dr. Philippon who does fantastic work as a surgeon and he's interested in cartilage regeneration in the hip, which solves a lot of problems. So in thinking about clinical translation, I would see Dr. Philippon loading our materials in some kind of syringe and actually using that material which looks like toothpaste, actually, if you look at it, looks like the toothpaste you use to brush your teeth every morning. And but it is composed of these tiny structures that we talked about designed to in this case to grow cartilage. And so he's actually seen the material and he thinks it would be really fantastic to be able to use it because it would be very easy to deliver it to the patient right at the site where the patient needs the cartilage to be regenerated. What I bring with me after this weekend is just the thought that I want to keep interacting with the folks here in Vail, with these brilliant surgeons and work closely with them to facilitate the translation to the clinic. It is indeed a very exciting prospect. I mean, what I learned this weekend and have also learned it in the past and other occasions when I have been here is the fact that nothing can replace the knowledge that surgeons have and the experience they have in understanding what can be translated and what cannot be translated into the clinic. I think that they are definitely aware through their experience on what is the best way to do that. And so I have the great privilege to be working with them. And I owe this to Mike Shannon and Mary Sue Shannon who are sponsored some of our work. And Mike Shannon was, in fact, the person that put me in contact with everybody here in Vail. And so it's very exciting indeed. Thank you so much.
