Title: Photochemically crosslinked collagen scaffolds and methods for their preparation
Usefulness: Photochemically crosslinked collagen scaffolds and methods for their preparation
Summary: (M1) is useful for producing a crosslinked collagen and collagen composite scaffold (claimed), where the collagen scaffold is useful for tissue engineering (to repair or replace defective tissues including tendons, ligaments, intervertebral discs, nerves and blood vessels) and controlled drug delivery.
Novelty: Producing crosslinked collagen and collagen composite scaffold, by contacting three-dimensional extracellular collagen matrix with photosensitizing reagent, forming crosslinked scaffold by matrix irradiation, and dehydrating scaffold
