abstract = {Numerous sensitive nanobiosensors are reported for various
bioassay applications as a result of the development of
materials science and nanotechnology. Among these sensors,
nanowire (NW) field‐effect transistors (FETs) represent
one of the most promising practical biosensors for
ultrasensitive clinical diagnostic tools. Most studies
mainly focus on how to achieve a lower detection limit but
pay less attention to the long settling time effect for the
detection of very small concentrations of molecules in a
solution. In this study, single silicon NW FETs with
long‐term stability is fabricated to investigate the
settling time process at small concentrations of cardiac
biomarkers relevant to myocardial diseases. It is found that
the settling time strongly depends on the type of molecule,
its charge state and analyte concentrations. For low
concentrations, the time for measurement signals to settle
down is relatively long. Therefore, it is essential to
understand the settling time effect in Si NW FET‐based
biosensing processes to ensure the accuracy and reliability
of the detection signal. An alternative approach is
demonstrated to circumvent the long measurement time by
utilizing reaction kinetics parameters for the fast
determination of low‐concentration detection, which also
benefits the optimal balance between suitable detection time
and reliable detection results.},
