Abstract:
1. An apparatus for introducing particles into a microdevice conduit, comprising: a microdevice comprised of a substrate having a microchannel formed therein and a cover plate arranged over the substrate such that the cover plate in combination with the microchannel at least partially defines the conduit, wherein the conduit extends from an inlet to an outlet, and the inlet terminates at an opening located on an exterior surface of the microdevice; a dispenser containing fluid and having a dispensing orifice, wherein the dispensing orifice is sized to allow flow of the fluid therethrough without clogging; a means for positioning the dispensing orifice and the inlet in fluid-tight alignment with each other without extending the dispenser past the opening of the inlet; and a means for applying pressure to the fluid in the dispenser so as to transport the fluid into the conduit via the dispensing orifice and the inlet.
