CD Biosynsis uses our synthetic biology platform to help our customers explore the diversity and material properties of polysaccharides as a valuable source of bio-based materials and achieve their potential widespread applications. Our multidisciplinary team can offer their expertise in a wide range of fields such as synthetic biology, materials sciences, and synthetic chemistry to help our customers overcome the challenges in preparing polysaccharide-based materials with desirable or innovative properties.
Background
Polysaccharides are naturally occurring macromolecules that play an important role in structural support, energy storage, and cellular signal transduction. Polysaccharides have attracted great attention due to their excellent biological and physiochemical characteristics, such as biocompatibility, biodegradability, natural abundance, high bioavailability, and nontoxicity, making them ideal materials for a wide range of applications. Polysaccharide-based biomaterials, which are being extensively explored, are of high value for the discovery of new bio-based materials. Synthetic biology strategies offer attractive options for the sustainable and large-scale production of polysaccharide-based materials with desirable properties for industrial and medical applications, and are expected to be a promising alternative to the current production of polysaccharides from natural sources.

Applications of Polysaccharide-based Materials
CD Biosynsis helps our customers explore the potential of polysaccharides-based materials for different applications through the in-depth study of the composition, structure, physicochemical properties, and biological functions of polysaccharides.
- Medical applications. The antibacterial, antiadhesive, antioxidant, procoagulant and other biological properties of polysaccharide can be used in the development of materials for medical applications such as drug delivery, would healing, tissue engineering, regenerative medicines, vaccines, and diagnostics.
- Food applications. Polysaccharides can be used as food stabilizers and additives or as raw materials to produce materials for food packaging applications.
- Environmental applications. Possible environmental applications of polysaccharide-based materials include air filtration, wastewater treatment, environmental sensing, etc.
- Energy applications. Polysaccharides can be used as components in energy storage systems. For example, carboxymethyl cellulose (CMC)-based binders can be used in lithium-ion batteries.
