MP9 - A microfluidic system with integrated inkjet-printed capacitive sensors for biosensing applications

Résumé fourni par la source

This paper presents a novel microfluidic system integrating an inkjet-printed interdigitated capacitive biosensor, specifically targeting Tumor Necrosis Factor alpha.The system exploits an aptamer-based functional layer whose dielectric permittivity is affected by the target analyte.Low-cost, rapid prototyping technologies have been exploited for the device fabrication.Experimental results demonstrate good sensor performances, especially within the low detection range of TNFα.In particular, a sensor responsivity of 15.291 fF/pM in the range [0-1] pM has been estimated.
