New NFC-film can be made waterproof or change its electrical charge.
Aalto University researchers have developed an inexpensive and environmentally friendly film from nanotsellyulozy for medical tests. New invention makes it possible to perform tests at home or in a doctor’s office, instead of the usual laboratory.
Nanofibrotsellyuloznaya film (short film of NFC-English name nanofibrillated cellulose / cellulose nanofibrillirovannaya) has a more versatile use than traditional plastic film. On top of NFC-film is more environmentally friendly.
In the manufacture of the film at the plant, the material added components that react with the test substance. The test film can put a drop of blood, water or other substance to be analyzed. Already on film antibodies react with the sample and will show whether it, for example, allergens or bacteria. After that, the color of the sample may change if there are those substances, the presence of which tried to identify with the analysis.
? Thanks to the new film, you can do a variety of tests much faster, while not losing any quality. Right on the doctor can identify the microbes that cause disease patient, and in his home a person can control the presence of allergens. The films will be used not only for medical purposes, for example, they can be used to determine the purity of the water, – says on the site, Professor Hannes Orelma Aalto University, which trains future physicians.
Initially, the creation of the film nanotsellyuloznoy suffered a fiasco, as the material is absorbed part of the test sample. A newly developed method of coating material nanovoloknistym special cellulose gel film made more environmentally friendly, water-proof and resistant to the absorption of the test sample.
The research project, funded by the Finnish Foundation for Technology and Innovation Tekes, Aalto University in addition to specialists, attended by their colleagues from the University of North Carolina. The scientific article on the current study has been published in October 2012 in the journal «Biointerphases».
