Highly sensitive sensors are now required to measure extremely low level of biomarkers and detect early stages of diseases.
Highly sensitive sensors are urgently required to measure extremely low level of markers and detect early stages of the disease, which will increase the survival rate of patients [10].
This approach enables researchers to measure extremely low levels of mutant that could in turn lead to the improved detection of minimal residual disease and less invasive diagnostics.
However, as MS technology advances, it will be possible to measure extremely low estrogen levels, in the femotogram range, and improve discrimination [ 26].
However, higher sampling rates or longer sampling times may be necessary to measure extremely low virus concentrations in ambient air, and both of these approaches have the potential to injure or destroy viruses and thus inhibit detection.
For measuring the extremely low deflections of the microcantilevers, a high precision optical readout approach based on a fiber optical reflective light intensity readout approach were presented.
Furthermore, due to a very small number of redox active molecules on the surface (in the range of hundreds of thousands only per measurement), measured currents are extremely low, in the picoampere range, the limit of our measuring abilities.
Since it is problematic to measure viscosity at extremely low temperatures such as − 47 °C, the initial viscosity measurement temperature was chosen as − 20 °C.
