Dripping shows a wide variety of characteristics from periodic to chaotic but has never been clearly connected with the physical properties of a system.

The invention can spray hundreds of different DNA sequences on a small plate, and researchers can then screen mixtures for the presence of the particular DNA they wish to study.
