P2-3: Stretchable Ion Responsive Hydrogel with Controlled Response: Abhishek Pachauri1; Jeff Bates1; 1University of Utah
As a result of excellent biocompatibility and swelling abilities, hydrogels find enormous uses in biomedical devices and drug delivery. Here, an ion responsive hydrogel with improved toughness, mechanical strength and controlled response is synthesized. The hydrogel is designed to swell in Phosphate Buffer solution so that the volume of hydrogel will increase several times which can be translated to do the required sensing or actuation operation. The hydrogel is tested for its mechanical strength, toughness and viscoelastic properties and a comparison between these properties before and after swelling is performed. For the precise control of swelling and deswelling operation of hydrogel, swelling kinetics is studied.
P2-4: A Skin Testing Diagnostic Device: Anthony Annerino1; Pelagia-Iren Gouma1; 1The Ohio State University
The medical science has been aware of the diagnostic potential of the gaseous metabolites emitted from the human body for centuries, however even with the recent technological advances, this potential has not been fully realized. We present here a skin testing device is like a “magic wand” passing over one’s arm that reads the gaseous headspace above the skin for disease, creating the new era for non-invasive personalized medicine. We focus here on an electronic olfaction device based on gas sensing utilizing a small number, just four, of metal-oxide nanowire sensors that are specifically sensitive to the biomarkers of interest (isoprene, ammonia, acetone and NO). We have been testing the device performance using synthetic gas mixtures that simulate the headspace of skin gas emissions.
P2-6: Non-clinical Method For Diagnosing Cystic Fibrosis: Cassidy Holdeman1; 1University of Utah
Cystic Fibrosis (CF) is a genetic disorder, and it is important to identify early on to prevent serious health issues. Current methods of identifying Cystic Fibrosis using the sweat test are accurate but uncomfortable for children. This research looks into biosensors as a more comfortable and non-clinical alternative by using a polymer matrix, such as hydrogels, polyurethane, or carrageenan, to either suspend or hold chloride ionophore and polarity sensitive dye (PSD). Exposure to sweat shows a color change in response to elevated chloride ions present in the sweat of CF patients.
