A development platform for autonomous biosensors

In our explanatory video we show you the principle of our interface and the possible applications of the technology - just have a look! (Language in video - german)

Breath is more and more becoming an attractive diagnostic medium - it allows non-invasive sampling and is unlimited in terms of volume and time. Analytes such as cytokines, proteins, bacteria, viruses and cell fractions are accessible via this aerosol. The newly developed functional surface enables contact-free breath gas analysis with potential applications in the early detection of diseases or in professional and amateur sports.


The present invention relates to a method for producing a cellulose layer for detecting at least one analyte, comprising (i) producing a cellulose layer by applying a stable dispersion of cellulose and/or a cellulose derivative to a suitable carrier, and (ii) immobilizing at least one ligand on the cellulose layer. The invention also relates to a cellulose layer produced according to said method. The present invention additionally relates to assosiated detection methods, devices, kits and uses.
