Precision DLP Printing of Multifunctional SilMA Hydrogels Enabled by Sepia Melanin for On-Demand Wound Therapy

evaluations confirmed that the scaffold effectively controls infection (nearly 98% antibacterial rate), mitigates oxidative stress, increases the polarization of M2 macrophages, and accelerates wound closure through enhanced collagen deposition and neovascularization. This work establishes a unified strategy that seamlessly integrates high-resolution printability, intrinsic bioactivity, and on-demand responsiveness into a single biocompatible platform, offering a versatile and generalizable approach for advanced tissue regeneration in infection-compromised environments.
