To create a new wound-care gel, researchers used a common hydrogel, Gel-MA, and created several combinations infused with platelet-rich blood plasma (PRP) and polylysine (PL). To test the gel’s ability to battle bacteria, they added E. coli and S. aureus, the bacterium that causes staph infection, and used scanning electron microscopy and plate counts to determine the best combination.
