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. 

Similar to our investigation in image 2 and 3, we needed to examine the structure properties of the most hydrated substrate, which is the porous alginate hydrogel.
