Glutamate volume per 100 ms injection (nL) versus applied voltage (V) characteristic of the EOF device found using the meniscus tracking method. Voltage pulses were applied for 100 cycles with a time-width of 100 ms at 1 Hz frequency. The plot obtained from three trials for each actuation voltage shows that higher glutamate injection volumes can be achieved by increasing the voltage amplitude.
