Abstract
Polymer-based micro-cantilevers for depositing material onto a surface include, in one embodiment, a body portion, an elongated beam portion sized smaller than and extending from the body portion and having a length greater than about 500 microns. The body portion includes a reservoir and the elongated beam portion having a passageway disposed therein. The passageway has an inlet opening in fluid communication with the reservoir and an outlet opening at a distal end of the elongated beam portion. The passageway comprises a width greater than 10 microns to about 100 microns, and a height of about 25 microns to about 100 microns. Methods for delivering fluid and living cells using the polymer-based micro-cantilevers are also disclosed.
