Biological, wound healing properties and molecular structures of chitosan, cellulose and alginate.

Biopolymer	Biological Properties	Molecular Structure	References
Chitosan	- Hemostatic agent due to positive charges that can bind to negative charges on red blood cells. - Antibacterial and anti-fungal. - Mucoadhesive properties - Wound healing acceleration and immune system stimulation.		[29]
Cellulose	- High water absorption and holding capacities. - Good wound exudates drainage capacity. - Support and enhance the growth and proliferation of cells.		[30]
Alginates	- Preserving a solid-like attribute at acidic conditions. - Hemostatic properties, which are useful for bleeding wounds. - Good mucoadhesive properties. - Barrier protects immobilized material toward physical stress.		[31]
