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.

Formulation and Evaluation of Novel Film Wound Dressing Based on Collagen/Microfibrillated Carboxymethylcellulose Blend.

Collagen is essential as a physiological material in wound healing, so it is often used in wound management, mainly as a lyophilisate. Collagen also has excellent film-forming properties; unfortunately, however, its utilisation as a film wound dressing is limited because of its weak mechanical properties, especially in its wet state. For this reason, modifications or combinations with different materials are investigated.

Films from poly-γ-glutamic acid and poly-ε-lysine as the potential wound dressings – formulation, preparation and evaluation.

Film wound dressings represent one of the options in wound therapy. Various polymers can be used for their production. Currently, research focuses on materials of natural origin, more friendly to the human body, which are in many cases able to participate actively in the wound healing process.

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.

Film wound dressing containing dexpanthenol - preparation and evaluation.

Currently, a wide variety of wound dressings of varying composition and effects is used to treat wounds. These include also film dressings where one of the promising materials for its preparation is sodium carboxymethylcellulose (NaCMC) as a material of natural origin with excellent film-forming properties. Its application is particularly in the field of absorbent dressings, films for wounds from this material are not used in practice yet.
