Why use AlgMA?
Alginate is widely used in biomaterials due to its stability and biocompatibility. By modifying it into AlgMA, researchers gain more control over gel formation and structure.
Compared to traditional alginate gels, AlgMA offers:
- More uniform and reproducible hydrogel formation
- Light-controlled crosslinking instead of ionic curing
- Better control over structure and shape
- Functional groups for further modification
It’s commonly used for:
- 3D cell encapsulation
- Tissue engineering scaffolds
- 3D bioprinting
- Drug delivery and release systems
Available AlgMA Hydrogel Options
Smart MCs offers Alginate Methacryloyl (AlgMA) hydrogel in two molecular weight options. Each product is supplied as a set with LAP photoinitiator included.
AlgMA-50K Set
Includes:
- 0.5 g AlgMA-50K hydrogel
- LAP photoinitiator included
AlgMA-50K has a molecular weight range of approximately 50–100 kDa. It has medium viscosity and is suitable for applications requiring easier handling, higher stiffness, and good structural definition.
AlgMA-300K Set
Includes:
- 0.2 g AlgMA-300K hydrogel
- LAP photoinitiator included
AlgMA-300K has a molecular weight range of approximately 250–350 kDa. It has higher viscosity and forms softer, more flexible hydrogels, making it suitable for cell encapsulation and soft tissue models.
Both options are supplied as white, sponge-like materials and can be used alone or combined with hydrogels such as GelMA or HAMA.
Performance
AlgMA is designed for consistent performance across different applications.
- Rapid gelation under light (typically within ~20 seconds)
- Tunable mechanical properties depending on formulation
- Wide stiffness range from soft to more structured gels
- Good printability and shape retention for 3D constructs
Detailed characterisation data is available on request.
Custom options
We can modify AlgMA depending on your application, including:
- Peptide-functionalised hydrogels
- Composite hydrogels (e.g. AlgMA + GelMA systems)
- Tailored mechanical or structural properties
