Geometry and surface-assisted micro flow discretization [PDF]
Journal of Micromechanics and Microengineering, 2006 This paper presents a micro flow discretization system that autonomously digitizes continuous liquid flow into nanoliter segments. Powered by the interactions between liquid flow and micro-channels, the discretization process does not consume any electricity or require any external control.
