WebCrystallisation in hanging droplets with 0.7–2 M NaCl and 50–100 mg mL−1 lysozyme was performed with one and two air bubbles and without an air bubble. The population densities of the crystals were increased up to 1.5 times in the droplets with an air bubble than the bubble-free droplets. WebBubble formation: (a) flow-focusing configuration and (b) T-configuration. (6.22) where μ is the viscosity of the liquid phase. The formation process does not depend on the surface tension. In a T-configuration, the two formation regimes are determined by the gap g between the bubble and the top channel wall.
