Abstract

We have succeeded in protein crystallization and processing by electrically-induced bubble knife. 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 knife 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. Furthermore, it was confirmed that cavitation induced by electrically-induced bubble knife enabled to curve protein crystal. It seemed that it has potential to contribute to more refined analysis.
