From: Electroporation on microchips: the harmful effects of pH changes and scaling down

The capacity of pH buffering.
(A) 100 μs pulse is applied 5 times and 20 times to the microchips, no color change is observed in modified buffer. (B) 500 μs and 1 ms pulse is applied 20 times. Bubbles are generated dramatically, whereas the color still not changes in modified buffer.
