From: Optomechanical micro-rheology of complex fluids at ultra-high frequency
The mechanical response of miniature silicon disks of thickness h = 220 nm and radius varying between 3 µm and 12 µm, once immersed in liquid 1-Decanol. Quality factor (a) and normalized frequency shift (b) as function of frequency. Measured (red) and analytically calculated values, using a Newtonian model (green) and the non-Newtonian model discussed in the text (orange). The error bars represent the 95% confidence interval, with the mean as the measure of center. Contributions to errors are discussed in the Supplements.
