(a) Standard deviation of each resonance frequency with various concentrations of FB cells at the same temperature and measurement setup. Each set of measurements is repeated 10 times. (b) Resonance frequency corresponding to fibroblast cell concentration (cells/μL) is plotted with the fitting curve of y = 2.24 × 10−5x + 13.4607 in GHz. Limit of detection is calculated using slope of calibration equation and standard deviation of blank response (resonance frequency corresponding to a sample without FB cells).
