Biocontractile microfluidic channels for peristaltic pumping.

Bio-actuated micro-pumps do not need any external power source and pose no risk of electrical or heat shock for the biological materials in lab-on-chip systems. Several different designs of bio-actuated micro-pumps based on the use of the contractile force of cultured cardiomyocites have been proposed earlier. Here we present a novel type of a bio-actuated micro-pump representing a microfluidic channel with a contractile wall.
