Chronic wound healing can be seriously impeded by the formation of biofilms, infections, peri-wound edema, hematoma, osteomyelitis, and the formation of reactive oxidative species (ROS). We hypothesize that a scaffold created from Silver-Doped Nanoceria (AgCNP) embedding silk can be beneficial to aid the wound healing process, inhibit inflammation and prevent microorganisms from forming a biofilm over the wound. Current wound healing methods such as intradermal injections are not advantageous to use since they can cause unwanted responses elsewhere in the body other than the wound site. Silk, however, has a positive impact on the wound healing effect and can be used as an alternative delivery method to deliver the drugs to the target site rather than intradermal injections since its degradability is controllable and it is bioresorbable, therefore it can get absorbed by the body and degrade safely without causing bodily harm. AgCNPs are used as they have antimicrobial/antioxidant properties to scavenge harmful ROS species at the wound site and can also modify silk for UV protection. As silk's degradability can be controlled, our experiment will involve collecting data on release studies conducted in vitro to see how long it takes for the silk patch to release the drugs. Our goal is to ensure the drug is not released immediately but rather over a longer controlled time manner to protect the wound while healing.
