Abstract

A microfluidics liquid dispensing unit comprises: a housing containing a liquid reservoir, the liquid reservoir having an ejection port. The liquid reservoir contains a test fluid in fluid contact with ejection port and further contains an expandable fluid or means for generating an expanding fluid. Activation of means for actively generating or expanding the expandable fluid, provides force generated by the expansion of expanded fluid which force is transmitted to dispensing fluid thereby ejecting and dispensing fluid through an ejection port.
