Targeted microbubbles and attachment to cells Targesphere-SA microbubbles (Targeson) with a mean diameter of 1. To analyze the performance of the swirl flow microbubble generator, particle image velocimetry (PIV) was used to characterize the dimension and distribution of microbubbles. The faster dissolution of the smaller microbubbles and the loss in the total number of microbubbles occur due to the Oltwald ripening phenomena. ufacturing microbubbles involves high-shear mixing, such as sonication of the aqueous medium containing shell-forming materials. The potential was positive under strong acidic conditions, and the inorganic electrolytes decrease the potential by increasing the amount of counterions within the slipping plane. The antimicrobial water generator comprises at least a microbubble generation part generating microbubbles to make microbubble-containing water, a silver ion generation part contacting water or the microbubble-containing water to elute silver ions, and a light irradiation part irradiating microbubble-containing silver ion water containing the. 5 s, and (d) 2 s.
