Abstract

<p>An approach to clarify the effect mechanism of microbubbles in various fields is shown. Fluorescence and absorption measurements were carried out on solutions of bovine serum albumin and hemoglobin. The fluorescence intensities of the proteins in a semipermeable membrane were observed in the absence and presence of air-, O2-, or N2-microbubbles. The microbubbles were not diffused through the semipermeable membrane from an outside to an inside solution. The air-microbubble system showed a significant decrease in the fluorescence intensity with respect to the bubbling time. This study raises the possibility that NO is produced from the reaction of nitrogen and oxygen gas in the air during crushing of microbubbles.</p>
