The development of advanced materials for biomedical applications has been a central focus of scientific research for decades. Hydrogels are one such class of materials that have gained significant attention because of their unique physicochemical properties. Hydrogels are three-dimensional networks of hydrophilic polymers that can absorb large amounts of water, leading to a swelling effect. They have been extensively studied for their potential use in drug delivery systems, tissue engineering, wound healing, and other biomedical applications. Among the various hydrogel polymers, Carboxy Methyl Cellulose-based hydrogels (CMC hydrogels) have garnered significant interest due to their biocompatibility, biodegradability, and versatility.

This review article aims to provide an overview of the recent developments in CMC hydrogels for biomedical applications. The article explores the synthesis, physicochemical properties, and various biomedical applications of CMC hydrogels.


Carboxy Methyl Cellulose (CMC) is derived from natural cellulose, which is the most abundant polymer on earth. CMC is a water-soluble derivative of cellulose and is made by the chemical modification of cellulose using carboxymethylation. CMC hydrogels are synthesized using various cross-linkers such as glutaraldehyde, bisacrylamide, and polyethylene glycol. These cross-linkers create a 3D network of CMC, which enhances the mechanical properties, swelling capacity, and biocompatibility of these hydrogels.

Physicochemical Properties

The physicochemical properties of CMC hydrogels can be tuned by adjusting the degree of crosslinking, the molecular weight of the polymer, and the pH of the solution. CMC hydrogels are highly biocompatible due to their natural origin and low toxicity. They exhibit excellent swelling behavior, which makes them ideal for drug delivery systems and wound dressings. CMC hydrogels also possess good mechanical strength, which is crucial for their use in tissue engineering applications.

Biomedical Applications

CMC hydrogels have been extensively studied for a range of biomedical applications. Some of the key applications of CMC hydrogels are discussed below.

Drug delivery systems: CMC hydrogels have been used as drug delivery systems due to their excellent swelling behavior and biocompatibility. They can be loaded with various drugs and release them in a controlled manner, providing a sustained release profile.

Wound healing: CMC hydrogels have been used as wound dressings due to their excellent biocompatibility and swelling behavior. They can absorb excess exudate from the wound and provide a moist environment for faster healing.

Tissue engineering: CMC hydrogels have been used as scaffolds for tissue engineering applications due to their excellent mechanical strength and biocompatibility. They can support cell growth and differentiation, leading to the formation of new tissues.


In conclusion, CMC hydrogels are a promising class of materials for a range of biomedical applications. They possess excellent physicochemical properties, including biocompatibility, biodegradability, and versatility. CMC hydrogels can be synthesized using various cross-linkers, which can be adjusted to tune their physicochemical properties. They have been extensively studied for drug delivery systems, wound healing, and tissue engineering applications. Further research is needed to explore their full potential in these and other biomedical applications.
