Description

Material Composition

• Gelatin-derived biopolymer functionalized with methacryloyl groups
• Retains intrinsic cell-interactive peptide sequences (e.g., RGD motifs)
• Designed for formation of hydrated, covalently crosslinked polymer networks

Physical & Chemical Properties

• Forms soft, elastic hydrogel networks upon light activation
• Tunable mechanical properties via concentration and crosslinking conditions
• High water content (>90%), enabling efficient nutrient and molecular diffusion
• Optically transparent, suitable for imaging-based analysis
• Thermally reversible sol–gel transition prior to crosslinking

Crosslinking Behavior

• Photopolymerization via UV (365 nm) or visible light systems
• Compatible with standard photoinitiators (e.g., LAP, Irgacure 2959)
• Rapid gelation kinetics with uniform network formation
• Enables spatial and temporal control over matrix formation

Handling & Preparation

• Supplied as lyophilized powder
• Reconstitution recommended at 37–50°C
• Photoinitiator added prior to light exposure
• Sensitive to light after activation—handle under controlled conditions
• Avoid repeated freeze–thaw cycles to maintain material integrity

Performance Characteristics

• Consistent crosslinking response across batches
• Reproducible mechanical tuning across experimental setups
• Stable hydrogel formation with minimal structural variability
• Supports formation of well-defined 3D hydrated structures
