Scientists in Finland develop bioactive sprays and surgical dressings with berry extracts and nanocellulose

Berry extracts, rich in antioxidant and antimicrobial compounds, are combined with nanocellulose to create thin films that protect the skin and promote healing.

Researchers from the Finnish center VTT Technical Research Centre of Finland have developed innovative bioactive sprays and surgical dressings using berry extracts and nanocellulose, with promising applications for dermatology and regenerative medicine.

Berry extracts, rich in antioxidant and antimicrobial compounds, are combined with nanocellulose to create thin films that protect the skin and promote healing.

Nanocellulose, a natural material extracted from wood, provides a nanometric structure capable of forming flexible and resistant films. This biopolymer is highly compatible with the human body and, combined with bioactive extracts from berries, it works synergistically to enhance skin protection and regeneration.

Panu Lahtinen, Senior Scientist at VTT, explains: "The fast-acting surgical spray and effective dressing are based on a manufacturing process we have developed, in which the surface and pores of a nanocellulose film are impregnated with berry extract, preventing the antimicrobial compounds from being trapped in the fiber network. VTT has more than 15 years of experience in lab-scale and pilot-scale manufacturing of nanocellulose gels and films."

Technology has applications both in the treatment of surgical wounds and in advanced dermatological products, such as skin care sprays, capable of acting as protective barriers and promoting the healing of minor wounds.

BERRIES AND THEIR ANTI-INFLAMMATORY PROPERTY.

This advancement has significant implications in biomedicine, as the use of natural and biodegradable materials allows for the development of more sustainable and environmentally-friendly solutions. Additionally, these products are highly versatile, opening the door to new applications in both the medical sector and the cosmetics industry.

The use of berry extracts is especially relevant in the context of bioactive products, as these fruits contain large amounts of polyphenols and other biochemical compounds with anti-inflammatory properties, which makes them an ideal source for products that aim not only to protect, but also to improve skin health.

This is how the associate professor and senior advisor at VTT, Kirsi-Marja Oksman-Caldentey, explains it, "our research has identified antimicrobial compounds in various wild berries, including sea buckthorn, blueberry, strawberry, cloudberry, cranberry and raspberry. Large-scale production is easier with the raspberry, as there is enough raw material. To process the seeds, it is necessary to find a company with experience in this task within the value chain".

The VTT research team continues to explore new ways to integrate bioactive components and nanomaterials for cutting-edge health applications, ensuring that future developments continue to positively impact both medicine and the cosmetics industry.
