Top view of the 3D printed sensing gate plate showing the gold-plated circular areas and the paths to the contact pads. The plate is divided into 6 areas each one assigned to the sensing of the fluid of one patient. The colour codes identify the gates (in triplicates) that are biofunctionalized with the capturing antibodies against MUC1 and CD55 or the probes to bind KRASmut. Each patient fluid is also exposed to 7 gates that are biofunctionalized with BSA for the negative-control experiments.
