Serum‐Integrated Dopamine–Hyaluronic Acid Hydrogels for Injectable Soft‐Tissue Microenvironment Modulation
Hyaluronic acid (HA) hydrogels are widely used as injectable fillers for soft‐tissue augmentation; however, most currently available formulations primarily provide structural support with limited biological activity. This work establishes design principles for integrating autologous biological components into catechol‐...
