A New Standard in Medical Biomaterials

For decades, cellulose-based materials have played a vital role in wound care and medical applications. From cotton gauze dressings in World War I to modern hydrocolloid and alginate dressings, cellulose has continuously evolved to meet clinical needs. Now, with the advent of nanocellulose technology, a new generation of biocompatible, functional wound dressings and medical implants is emerging.

Cellulose Use in Wound Care: Evolution Over Time

• World War I (Early 20th Century): Cellulose-based materials, such as cotton gauze, were widely used to dress wounds. Cotton, a natural source of cellulose, provided high absorbency and was effective in managing wound exudate. While absorbent, these materials lacked moisture control and wound healing properties.

• 20th Century – Introduction of Specialized Cellulose Dressings: Researchers began developing advanced cellulose-based dressings to improve wound care outcomes. These dressings were designed to maintain a moist healing environment, prevent infections, and facilitate tissue repair.

• 1960s – Hydrocolloid Dressings: Hydrocolloid dressings, containing cellulose derivatives, were introduced.These semi-occlusive dressings helped manage wounds by absorbing exudate while creating a protective barrier over the wound. The gel-like consistency formed when in contact with wound fluid improved healing and reduced dressing changes.

• 1970s – Alginate Dressings: Derived from seaweed-based cellulose, alginate dressings became a breakthrough for managing heavily exuding wounds.These dressings offered superior absorbency while conforming to the wound bed, making them ideal for burns, chronic wounds, and surgical sites.Their ability to form a gel-like barrier while maintaining moisture balance improved healing efficiency.

• Present Day – Cellulose and Use of NFC in Wound Care: Cellulose nanofibers are now being explored for their unique properties in wound healing. NFC has a high surface area, allowing for enhanced moisture retention and optimal cell growth conditions. As seen in FibDex® (the first CE-marked nanocellulose wound dressing), NFC provides improved wound healing with minimal scarring, better adherence without synthetic binders and a sustainable, biocompatible highly effective alternative to traditional dressings.

The evolution of cellulose in wound care reflects the continuous advancement of materials from basic cotton dressings to high-performance nanocellulose dressings, transforming patient recovery and medical treatments.

These superior properties position NFC as a next-generation biomaterial for wound care, tissue engineering, and medical device development.

Competitive Advantages of NFC vs. Current Solutions

NFC stands out as a superior alternative to conventional synthetic hydrogels and polymer-based materials, offering key competitive advantages:

• Unique in the Market: Unlike most hydrogels, NFC is one of the few non-degradable options available without synthetic polymers, making it a distinct choice for long-term medical applications.
• Extended Effect with Fewer Injections: NFC provides a long-lasting impact, reducing the need for frequent reapplications or injections, thereby improving patient compliance and comfort.
• No Foreign Body Reactions: Unlike polyacrylamide (PAA), polymethyl methacrylate (PMMA), and polydimethylsiloxane (PDMS), NFC does not cause immune or foreign body reactions, ensuring better integration with biological tissues.
• Cost-Effective and Scalable: NFC can be produced in large volumes, making it a cost-efficient solution for medical and industrial applications.
• Regulatory Compliance: NFC can be classified and regulated as a medical device, making it an attractive biocompatible material for implantable and therapeutic use.

These competitive advantages make NFC an excellent choice for medical professionals, researchers, and manufacturers looking for a safer, long-lasting, and more sustainable alternative to synthetic biomaterials.

The unique properties of nanocellulose—biocompatibility, tunability, and mechanical stability—underpin its integration into the medical device sector. From wound healing to drug delivery systems, nanocellulose offers diverse solutions to long-standing challenges in healthcare. In particular, when NFC is processed into a hydrogel, it is temperature stable, has shear-thinning properties, and is easy to inject, making it ideal for non-invasive delivery into the body. Plant-derived nanocellulose-based hydrogels that have no additional components added also show good biocompatibility in pre-clinical trials with minimal risk of inducing systemic toxicity or fibrotic capsule formation. 

Wound Healing

Nanocellulose-based hydrogels have been successfully used as wound dressings, particularly for donor site treatments. The reconstituted hydrogel in the dressing promotes healing by maintaining a moist environment, reducing inflammation and the need for dressing changes. This makes them ideal for treating burns and surgical wounds as they provide an effective barrier while accelerating tissue regeneration.

Beyond passive dressings, research is exploring the use of nanocellulose for active wound care. The material’s tunability allows researchers to incorporate antimicrobial agents or growth factors. For example, hydrogels infused with these additional active components are being developed to enhance healing in chronic wounds, such as diabetic ulcers.

Orthopedic Implants

Nanocellulose’s mechanical strength and stability make it suitable for orthopedic applications. The rigidity of nanocellulose fibers, combined with their injectability, can enhance the longevity and performance of implants. It offers the potential for long-term durability for load-bearing devices.

Implantable Scaffolds

Tissue engineering presents one of the most exciting frontiers for nanocellulose in medical applications. Its structure mimics the extracellular matrix, fostering an ideal environment for cell growth and differentiation. For example, in cartilage regeneration, nanocellulose scaffolds can replicate the natural supportive framework of cartilage tissue. This not only improves cell adhesion and proliferation but also paves the way for regenerative solutions in areas with limited healing capacity, such as the knee. Such advancements hold immense promise for treating osteoarthritis and other degenerative conditions.

Drug Delivery Systems

Nanocellulose excels as a drug delivery medium, thanks to its capacity for controlled therapeutic release. By adjusting the material’s concentration or form, researchers can fine-tune how quickly or slowly drugs are released into the body. This offers designers an alternative to conventional carriers, which often decompose too quickly or create byproducts harmful to the patient. Furthermore, nanocellulose hydrogels can encapsulate sensitive drug compounds, safeguarding their efficacy throughout the delivery process. This makes them particularly effective for localized treatments, where precision is critical. 

Currently, nanocellulose is well-suited for topical use and as permanent drug delivery implants, however, in vivo data also shows great promise for nanocellulose for short-term drug delivery. In this case, further development and clinical validation of enzyme mixes is still required. Whether used as a wound dressing, implantable scaffold, or drug carrier, nanocellulose can significantly improve patient outcomes. The material’s stability reduces the need for repeated interventions, lowering overall healthcare costs. The biocompatibility of animal-free nanocellulose minimizes the risk of adverse immune reactions, reducing patient complications and hospital readmission rates. For healthcare systems facing increasing economic and regulatory pressures, nanocellulose represents an adaptable, cost-effective solution.
