Photoinitiator-free gelatin hydrogel microneedles for acute gouty arthritis treatment
Photo-crosslinked microneedles (MNs) are widely used in biomedical applications, but their dependence on exogenous photoinitiators continues to pose a fundamental challenge to their further advancement. Herein, we have developed a hydrogel MN system loaded with self-assembled nanoparticles (NPs). The NPs are composed o...
