Preventive cardiovascular disease diagnostics plays a vital role reducing the critical fatality rate by allowing to take timely necessary precautions. Here, we demonstrate the exceptional properties of aptamer modified graphenebased FET (GFET) for cardiac troponin I (cTnI) specific sensing in different bodily fluids. Concentration-dependent measurements made with cardiac troponin I (cTnI) on an aptamer/polyethylene glycol (PEG) modified GFET exhibited real-time detection of cTnI from 1-400 pg mL-1 in 0.01× phosphate-buffered saline (PBS) solution. The sensor performance is within the clinical important window of 10 pg mL-1 to 500 pg mL-1 , allowing the differentiation between healthy, and people with low and high risk for myocardial infraction (AMI). Even more important is the very reproducible shift and neglectable leakage current of the individual IDSVGS-curves upon contact with cTnI solutions. To further evaluate the applicability of the developed point of care device for troponin I sensing in serum, samples of 15 patients with different troponin levels were analysed for their troponin I levels. The 15 patients were groupedShow less >
