In the next year, they also fabricated the biosensor instrument using a silicon nanowire field effect transistor (SiNW FET) for cardiac troponin I (cTnI) in acute myocardial infarction (AMI) and the cTnI monoclonal antibody (mAb-cTnI) was used as the BREs [8]. Here, TNNI3 is linked to myocardial infarction.
