Affecting Collagen Fiber Diameter and Pore Size
08/26/19
Abstract:
We utilized polymerization temperature (4–37°C) to manipulate collagen hydrogel fiber diameter, space-filling properties, and cross-link density. Multiphoton microscopy and scanning electron microscopy reveal that as polymerization temperature decreases:
- Fiber diameter increases
- Pore size increases
- Hydrogel storage modulus decreases
- Second harmonic generation decreases
