Nanocellulose – future of medical devices

By Otto Soidinsalo 16. January 2018

If you google the word medical device, you will get pictures of sophisticated hospital equipment and diagnostic devices. In practice, a term medical device is wider than just that and covers a range of different kinds of articles, starting from plasters and bandages to endosseous implants and implantable pacemakers, intended to be used for therapeutic purposes of humans or animals. We have previously written about the role of MFC in wound care products and today we are going to take a step deeper to the current status of nanocellulose in medical devices, especially topical and implantable ones.

Shifting paradigms: introducing alternative technologies

By Mats Hjørnevik 9. January 2018

This week’s blog post started its life when I attended a stakeholder forum which was organized by the Bio-Based Industries Joint Undertaking (BBIJU), a part of the EU H2020 initiative. I listened to a high number of innovators within several fields such as bio-fuels, bio-chemicals, as well as new and more sustainable materials. I started a line of thought, where the word paradigm occurred to me; I am part of a generation raised in the latter part of the 20th century where a majority of things we take for granted are based on technologies from the petroleum sector. The paradigm has given opportunities and challenges, but how does this paradigm affect us and our thoughts on innovation?

Research review: Paper-based electronics – the future of advanced electronics?

By Mats Hjørnevik 26. December 2017

I stumbled over an article the other day, grasping the opportunity that’s emerging in relation to making electronics based on cellulose sources. The world around us is in an exponential pace making innovations in electronics. So I asked myself the question after reading the article I in this blog post will refer to: can we make smarter electronics with paper-based versions?

What makes cellulose fibrils a good oxygen barrier

By Anni Karppinen 21. December 2017

Cellulose fibrils has shown great potential as an oxygen barrier in packaging. This has led to numerous research projects trying to utilize the potential in practice. But how does the fibrils actually create the barrier towards oxygen?

Water holding capacity - how cellulose fibrils does it

By Anni Karppinen 12. December 2017

Water holding capacity, or high water retention value, is often mentioned as a key property of cellulose fibrils. When it is dispersed into water, the fibrils trap water between them and do not release it easily. As a consequence, even rather low concentration of MFC in water has gel-like appearance since the water is not able to flow freely. What is behind this? Let’s try to find out.

Biodegradability of cellulose fibrils

By Anni Karppinen 5. December 2017

Plastic microparticles found in the environment have gotten a lot of attention lately. Many of the plastics are very durable and do not degrade in a reasonable time in the nature, although today there are also biodegradable plastics available. Small pieces of plastic can be found almost everywhere on the Earth and it is not fully understood what kind of consequences that could have for the human beings and environment. Therefore, replacing non-biodegradable plastics with biodegradable materials in packaging, clothes and cosmetics has high focus right now. Cellulose fibrils come from wood or other natural resources; are they biodegradable? Can they replace non-biodegradable plastic and reduce the amount of microplastics in the environment?
