Spherical particles having a size on the order of 0.1 to 100 microns in size are created by systems and devices of several types. The device includes a source of a stream of gas which is forced through a liquid held under pressure in a pressure chamber with an exit opening therein. The stream of gas surrounded by the liquid in the pressure chamber flows out of an exit orifice of the chamber into a liquid thereby creating a monodispersion of bubbles with substantially uniform diameter. The bubbles are small in size and produced with a relatively small amount of energy relative to comparable systems. Small particles of liquid may also be produced. Applications of the technology range from oxygenating sewage with monodispersions of bubbles to inhalation therapy with monodisperse aerosol dispersions of pharmaceutically active drugs.

[What is claimed is:] [1.]forcing a gas from a source opening into a first liquid; andmoving the first liquid, in a pressure chamber surrounding the source opening, out of an exit orifice in the pressure chamber wherein the gas is focused by the surrounding first liquid creating a stable cusp at the interface of the gas and the first liquid which cusp then creates a gas stream which flows out the exit orifice into a second liquid wherein the gas stream breaks up forming bubbles of the gas in the second liquid.
