Abstract:
Researchers at Aalto University have succeeded in developing a durable and affordable nanofibrillar cellulose film platform to support medical testing. New environmentally friendly, reliable nanofibrillar cellulose (NFC) platforms are more diverse than plastic films.

Nanofibrillar cellulose film to ease performing medical tests

Helsinki, Finland | Posted on October 23rd, 2012

New film can be made, for instance, hydrophobic, hydrophilic and the electric charge can be changed. This will enhance the possibility of conducting thousands of different medical tests at home or in physicians' receptions instead of waiting for results from laboratories.

A platform is coated with the new film in the factory. The film is injected with substances that will react to the tested substance. At the place of testing, blood, water or another test material will be applied on to the film. The antibody injected onto the film will absorb the sample, depending on whether it contains substances causing allergic reactions, or bacteria, for example. Then the test result is visualised with the help of colour‑changing chemistry, for example.

Thanks to the new film, various tests can be conducted faster without compromising reliability. It will now be easier to detect microbes that cause illnesses in the physician's reception, or to monitor allergens at home. In addition to medical diagnostics, the film can be utilised to study water purity, for example, says doctoral candidate Hannes Orelma at Aalto University.

Previous attempts to produce a nanofibrillar cellulose platform have failed when the porous plate absorbed part of the sample. Now researchers have developed a method of producing a water‑proof nanofibrillar cellulose gel that will not absorb samples. They have also made great efforts to ensure sufficient film durability.

The article Surface Functionalized Nanofibrillar Cellulose (NFC) Film as a Platform for Immunoassays and Diagnostics was published in Biointephases journal. North Carolina State University participated in the study in addition to Aalto University. The research project was funded by Tekes - Finnish Funding Agency for Technology and Innovation.

About Aalto University
Established in 2010, the Aalto University is a new university with centuries of experience. The Aalto University was created from the merger of three Finnish universities: The Helsinki School of Economics, Helsinki University of Technology and The University of Art and Design Helsinki. Aalto University School of Science and Technology has been divided into four new schools starting from 1st of January 2011. The six schools of Aalto University are all leading and renowned institutions in their respective fields and in their own right.

The combination of six schools opens up new possibilities for strong multi-disciplinary education and research. The new university's ambitious goal is to be one of the leading institutions in the world in terms of research and education in its own specialized disciplines.
