Area of Science:

  • Biomaterials Science
  • Polymer Chemistry
  • Medical Applications

Background:

  • Chitin is a naturally occurring polysaccharide found in arthropod exoskeletons and fungal cell walls.
  • Chitosan, a derivative of chitin, is produced through deacetylation and possesses unique physicochemical properties.
  • Both chitin and chitosan are biocompatible, biodegradable, and exhibit antimicrobial activity, making them attractive for biomedical research.

Purpose of the Study:

  • To elucidate the scientific foundation for the use of chitin and chitosan as biomaterials.
  • To describe the inherent nature and key properties of chitin and chitosan.
  • To highlight the potential of these biopolymers in various medical fields.

Main Methods:

  • Literature review of scientific publications on chitin and chitosan.
  • Analysis of the chemical structures and physical characteristics of chitin and chitosan.
  • Synthesis of information regarding the biological interactions and medical applications of these polymers.

Main Results:

  • Chitin and chitosan exhibit versatile properties including biocompatibility, biodegradability, and mucoadhesion.
  • Their structural similarity to glycosaminoglycans facilitates interaction with biological systems.
  • Demonstrated potential in drug delivery, tissue engineering, wound healing, and antimicrobial therapies.

Conclusions:

  • Chitin and chitosan are highly promising natural biomaterials with a broad spectrum of potential medical applications.
  • Further research into their modification and clinical translation is warranted to fully harness their therapeutic benefits.
