These images represent material information necessary to improve drug delivery and health monitoring in the GI tract. 

We took this image of the fish surface to better understand how material structure plays a role when placing medical devices across hydrogels or simulated human tissue for intimate contact. 

The purpose of this research is to develop a universal device system as a drug and/or sensor loading platform for drug delivery and health monitoring in the gastrointestinal tract. 

The structure of the polyacrylamide gel has significantly smaller features, filled with bead-like fragile crosslinkers, facilitating the requirements in achieving intimate contact with soft and fragile substrates.
