Fidget Spinner (IMAGE)
Caption
(A) Photographs of a fidget spinner toy (left) and a diagnostic-fidget spinner (right). (B) Bacterial load detection by color changes. Orange color shows high bacterial cell load. (C) Fluid Assisted Separation Technology (FAST) enables rapid and robust enrichment of bacteria. (C-a) Cross-sectional view of the device depicting sample bacterial enrichment through the filter membrane in the conventional (upper) and FAST (lower) setups. (C-b) Images showing effective filtration during rotation and fluorescence images of bacterial cells enriched on the membrane for (1 and 3) conventional and (2 and 4) FAST filtration. Scale bar: 2 mm / 0.1 mm. (C-c) Flow volume of Dx-FS estimated at ω_max. (C-d) Number of spins by 10 independent subjects who spun Dx-FS. The angular velocities were measured, and the number of spins to elute 1 mL of liquid was estimated. (C-e) Measurements from (d) plotted for each subject. Red lines, dashed red lines, and gray and red boxes over the measurements (gray dots) denote the mean, median, standard error of mean, and standard deviation. The gray areas indicate the number of spins in (d).
