A MICROFLUIDIC DEVICE FOR CONTROLLED MOVEMENT OF MATERIAL AND A METHOD FOR DELIVERING A MATERIAL FROM A MICROFLUIDIC DEVICE

摘要

A microfluidic device for controllably moving a material of interest includes a holding cavity configured to hold the material of interest and at least one actuator configured to induce an activation material to expand or contract. Expansion of the activation material decreases the size of the holding cavity to cause the material of interest to be released from the holding cavity and contraction of the activation material increases the size of the holding cavity to cause the material of interest to be received into the holding cavity. The at least one actuator is operable at multiple levels between a zero induction level to a maximum induction level on the activation material to thereby controllably expand or contract the holding cavity to release or receive a specified volume of the material of interest.
