 Our eighth presenter is Sampada Acharya whose presentation is titled Nature-Inspired Pathogen Collection Device. Got to catch them all. I want everyone here to touch their closest surface and then rub their hands. You might have thought that this is a very simple gesture, very inconsequential and in fact you might be right. Over here, this very gesture doesn't really have any long-lasting negative impact. However, if you are in an infectious environment like hospitals, this very same innocuous gesture might in fact severely worsen your condition because of infections caused by pathogens present on surfaces. In fact, even today in the United States alone, one out of every 17 patients do not survive because of this. This is healthcare-associated infections. And clearly, this is not a problem that affects a small fraction of the population. This is something that can affect me, you, your loved ones, and every other human out there. So obviously, taking a sanitizer spray and spraying it on surfaces is not going to do the job. We have to actively and efficiently monitor hospital surfaces. A lot of work has been done in the field of pathogen detection. However, virtually no work has been done in the field of pathogen collection, which is extremely surprising. Pathogen collection materials like swabs and sponges are in fact known to be unreliable, inefficient, something that requires a very small amount of sample area, and also it is something that requires very close human interaction with the contaminated surface. This is exactly why my research involves creating smart, rapid, and scalable surface-level pathogen evaluation methodologies in order to mitigate these issues. I draw my inspiration from how the nanostructures on the feet of wall-climbing geckos allow them to climb on and stick to practically most surfaces on this earth. Based on these principles, I have designed, fabricated, and characterized several microstructures made of soft polymeric materials. As a proof of concept, I was able to demonstrate that my microstructured surfaces picked up significantly higher amount of particles comparable in size to pathogens as opposed to traditional sponges. And obviously, because this is CMU, I integrated my surfaces with a completely novel soft robot that allowed it to climb on various types of surfaces in both wet and dry conditions, and even on inclines that are especially hard. So now that I have these two components, I plan to integrate them onto a pathogen collection device that can successfully monitor infectious environments. If that will help us reduce the instances of healthcare-associated infections. This way, hospital visits can be the way they were meant to be, safe, and in order to make you feel better again. Thank you.
