FIG. 6.

EGT response⁴ in an inverter configuration to varying concentrations of ricin subunit B dissolved in phosphate buffered saline solution (PBS), milk, and orange juice, using a DNA aptamer¹¹⁰ for the capture agent. The control experiment uses the same device with bovine serum albumin (BSA) dissolved in PBS. The error bars correspond to the standard deviation between 3 and 5 devices.
