      Safety and storage

      ✅ Biocompatibility: Cytotoxicity is much lower than traditional initiators (NIH/3T3 cell survival rate>95%)

      ❄️ Storage conditions: 2-8℃, dry and away from light, dry powder is stable for>1 year; solution must be used within 2 weeks

      Application scenarios and solutions

      1. 3D bioprinting and tissue engineering

      Cell encapsulation hydrogel: 0.03-0.5% concentration achieves second-level curing, supporting cartilage repair scaffolds and skin tissue regeneration.

      2. Medical device coating

      Antibacterial hydrogel dressing: synergistic collagen (such as PureCol® #5005), the curing speed is increased by 30%, and the infection rate is reduced.

      3. Intelligent material development

      Photoresponsive drug carrier: Precisely control the drug release rate (tumor targeted therapy efficiency ↑40%).
