In recent years

with the development of regenerative medicine technique

there has been a heated attention and research about reconstruction of human organs by means of tissue engineering. One important factor of accelerate wound repair by designed dressing materials

which has significant impact on the structure and nature of regeneration tissue. Natural polymer chitosan (CS) has broad-spectrum antibacterial activity and powerful hemostatic function

non-harmful degradation products

has good biological compatibility

bioactivity and bio-degradability

which can effectively promote wound healing and tissue repair and regeneration in the field of biomedical dressing has broad application prospects. This article mainly reviewed in recent years

chitosan wound dressing design molding methods

and discuss the dressing performance and usage of different molding processes and antibacterial agents. It may contribute us to effectively design and develop new types of chitosan-based antimicrobial wound repair material.
