Abstract

original image

Multiple emulsions are formed using poly(dimethylsiloxane) microfluidic devices. The single emulsions (see image, left) are formed using a single drop maker with uniform wettability. The double, triple, quadruple, and quintuple emulsions (right) are formed using linear sequences of drop makers with alternating wettability.
