Abstract

As adsorbents directly interact with the biological fluid, they can induce normal physiological mechanisms for repairing body functionality. As a result, biopolymers are widely used as natural and biocompatible alternatives to synthetic adsorbents for establishing body homeostasis in medical treatment. In this regard, relevant properties of carbohydrate-based bioactive adsorbents can be tailored to contribute to the design of safer coatings surfaces for implant devices. This review explores the most common polysaccharide-based polymers applicable in blood-contacting devices for treating degenerative diseases, wound healing, and developing anti-thrombogenic surfaces. Furthermore, challenges and limitations of blood-contacting devices that must still be tackled and strategies to enhance their hemocompatibility are described to encourage their prospective use.
