摘要:
Microfluidic devices and in particular microfluidic devices incorporating a cascading valve arrangement for selectively controlling the flow of a fluid within the microfluidic device are described. Specific examples of a microfluidic device comprising a sacrificial valve (210) whose opening is triggered by the opening of a second valve (220), causing a retraction of a fluid spacer (213) thus bringing liquid (214) into contact with the dissolvable valve membrane (210).
