Formulation and evaluation of novel collagen/ carboxymethylcellulose blend film wound dressing.

Films are thin, flexible, and transparent wound dressings. They can be prepared from both synthetic and natural materials. In practice, synthetic polyurethane dominates, but research is mainly focused on substances of natural origin.

Collagen in combination with the acid form of carboxymethylcellulose in the form of a nonwoven textile as a modern wound dressing - formulation, preparation and evaluation.

The acid form of carboxymethylcellulose (HCMC) is less known than its sodium salt (NaCMC). However, it is commonly used as a sorbent for chromatographic columns and has a number of valuable properties for its use in wound care. As a wound dressing in the form of hydrofibers, it is already commercially available on our market.

Preparation and evaluation of bilayer films based on collagen and carboxymethylcellulose for wound therapy.

Collagen is the most abundant protein of the human body and a widely used biomaterial across sectors due to its favourable properties resulting from its physiological proximity. It plays a key role in the process of wound healing and tissue repair and is therefore used in modern wound dressings in various forms, either alone or in combination with other materials. Collagen films also offer potential applications for these purposes, because collagen has good film-forming properties and is commonly used in the food industry.
