Abstract
A new process is presented where the controlled coagulation of droplets is achieved through electrical forces. The charged droplets are produced by el ectrosprays operated in the cone-jet mode. The coagulation of oppositely ch arged droplets leads to the neutralization of the electrosprays. Furthermor e, this coagulation enables controlled mixing on a microscale and subsequen t chemical reactions inside the combined droplets. This process has many po tential applications in the production of "tailored" particles, particles o f uniform size and composition.
