Abstract
Latex material disposed in a solvent is injected into a sheath fluid into which the solvent is soluble, but the latex is not. The solvent being jetted from a vibrating nozzle forms droplets within the flowing sheath, which is then delivered onto an inclined hydrophobic surface reposing at a low angle to the jet. As the droplet containing stream strikes and flows down the surface, its velocity is taken up as the phase separation process for forming microparticles begins.
