Product Description

Advanced Biomatrix offers PhotoChitosan®, a purified and lyophilized methacrylated chitosan powder for photocrosslinkable hydrogels. PhotoChitosan® is a highly versatile solution designed for researchers and scientists seeking advanced materials for tissue engineering, drug delivery, and regenerative medicine applications. PhotoChitosan® provides 3D tunable gels with the unique attributes to be prepared at various concentrations and crosslinked to provide various gel stiffnesses.

PhotoChitosan® is offered in convenient kits that include a selected photoinitiator, provided separately as a powder. This allows for customization and precise control over the crosslinking process.


Catalog Number

Photoinitiator Included




PhotoChitosan with LAP


LAP (405nm)

PhotoChitosan with Ruthenium


Ruthenium (400-450nm)

PhotoChitosan with Irgacure
