Figure 2. Microbiopsy channel width and velocity optimisation.

Figure 2.

Channel width and velocity were varied to optimise the microbiopsy device configuration. Total DNA was used as a surrogate for sample size. Panel ( a) shows the DNA extracted from device with varying channel width and that the maximum amount of DNA was collected with 0.15 mm channel width. Panel ( b) displays high resolution scanning electron microscopic images showing different channel widths of the microbiopsy device. Panel ( c) shows the level of pain volunteers reported when different channel width microbiopsies were used. Panel ( d) shows the varying velocity applied and that the maximum amount of DNA was collected when the device was applied at 16.6 m/s. Panel ( e) shows the level of pain volunteers reported when application velocity was varied.
