❄️ 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%).
