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. 

Hitchhiking to a gourami fish is tough: gourami fish develop water tunnel structures at the center of their scales, which may function as biological sensors for detecting flow direction and hydrodynamic drag; intimate contact in this situation requires conformal locking with these bumpy and hollow structures
