In this paper, we designed a multifunctional wound dressing based on silicone gel.

This ensures prolonged and controlled drug release, achieving effective analgesia and wound protection. We used positron emission tomography/computed tomography (PET/CT) scanning to compare pain levels in rats, and favorable results were obtained in animal experiments. The PET/CT results showed a significant decrease in pain indicators in the experimental group compared to the control group, confirming that the analgesic function of the dressing designed in this study is effective.
