Biosensor for the detection of analytes in biological samples

Portable diagnostic device for the detection of analytes in biological samples. The biosensor allows a label-free quantitative detection. Simple use, no qualified personnel needed.

Market need: In the last years, different in situ diagnostic systems that allow early and simple detection of disease marker analytes have been developed. In this way, medical treatments can be implemented early, facilitating the recover of patients and reducing the costs for the health system.
The devices for qualitative detection are user-friendly, but don’t quantify the analyte and need to label the analyte to detect it, which increase the complexity of the device.
Quantitative devices need complex procedures that must be done by qualified personnel.

Proposed solution: A new electronic biosensor that allows quantitative detection of label-free analytes in a simple procedure.
The new device combines the use of an absorbent material that receives and transports the sample to be analysed, and sensor media that produces variable electric current according to the quantity of analyte present in the sample.

Competitive advantages
