Micrograph of monodisperse microbubbles
produced using a solution
containing 1 mg mL–1 oleosin and 10
mg mL–1 (PEO)78-(PPO)30-(PEO)78 and collected into a well in the PDMS device without the
use of plastic tubing. The inset shows the microbubble size distribution
for ∼500 microbubbles. μ, σ, and Cv in the inset represent the average
(in μm), standard deviation (in μm), and coefficient of
variation, respectively.
