We have succeeded in protein crystallization and processing by electrically-induced bubbles. The dispensed directional mono-dispersed micro-bubbles whose air-liquid interface tends to combine the ambient molecules due to by their stiction force on the surface of micro-bubbles. Electrically-induced bubble enables to generate mono-dispersed micro-bubbles by the electrolysis and local heat, and their generation speed was 30.8 kHz. These characteristics enable to agglomerate the protein molecule which brings to successful protein crystallization in the solution with low concentration. The rate of protein crystal-nucleation by electrically-induced mono-dispersed micro-bubble was much higher than that of control condition. The correlation between the number of bubbles and that of generated crystal was confirmed. Also, the crystallization of two different protein sample were successfully operated.
