Periodic Reporting for period 1 - FOODSELFI (FOOD Safety monitoring by Electrochemical Lateral Flow Immunoassay)
Berichtszeitraum: 2017-09-01 bis 2018-08-31
BIOLAN, a European SME leader in the field of biosensors for the food industry, aims to disrupt the market with the commercialization of rapid, low cost, disposable and quantitative one-step inmunobiosensors based on the Electrochemical Lateral Flow Immunoassay (ELFI) analytical technology.
In FOODSELFI, BIOLAN combined traditional qualitative lateral flow technology with quantitative electrochemical detection. This was conducted through the mass producible ELFI concept formulation: screen printed electrodes in the same paper material substrate of the lateral flow immunoassay.
The FOODSELFI prototype combined screen printed electrodes and hydrophobic barriers on paper based substrates in order to produce a platform capable of in-situ immunological reactions and electrochemical detection. The prototype was developed using a typical antibody model (interleukin-6) and was capable of determining 0 - 20 µg mL-1 per antibody molecule (n = 3).
1) Plastic/semi-paper analytical platforms - Paper analytical platforms
2) Qualitative or semiquantitative paper-based lateral flow immunoassay - Fully paper-based quantitative immunoassays
3) Caffeine-quantification in beverages is time consuming (hours) and requires expensive laboratory equipment/skilled personnel. Official method is based on chromatographic methods with spectrophotometric detection - In situ detection, user-friendly solution
