20090004754 | MULTI-WELL RESERVOIR PLATE AND METHODS OF USING SAME - The present disclosure generally relates to a multi-well reservoir plate and methods of using the same. The multi-well reservoir plate includes a frame portion coupled to a plate portion, where a number of receptacles are formed in the plate portion. The receptacles or wells are sized to receive and support a substance without permitting the substance to leak or discharge from a passage formed in a lower portion of the well and in fluid communication with an upper portion of the well where the substances is supported. In one embodiment, the wells are at least partially filled with a substance, the substance is supported the in the wells for an amount of time, and then the substance is discharged from the wells by applying a force to the substance. By way of example, the force may be a pressure applied to an upper surface of the substance, a pressure (e.g., vacuum) applied to a lower surface of the substance, and/or an inertial force generated by an acceleration of the substance. | 01-01-2009 |

20080261045 | Composite and layered particles for efficient delivery of polyelectrolytes - The invention provides a method of making composite particles for efficient delivery of polyelectrolytes to a target. Composite particles are made by two methods: 1) by first forming disperse polyelectrolyte condensates, by mixing the polyelectrolyte with a condensing agent, and then combining the disperse polyelectrolyte condensates with particles so that the disperse polyelectrolyte condensates bind to the surfaces of the particles or 2) combining particles with opposite charge polyelectrolyte to form a polyelectrolyte coated particles followed by a subsequent polyelectrolyte of opposite charge to form a composite particle. The invention includes composite particles, where each composite particle is comprised of a particle with the polyelectrolyte from one or more polyelectrolyte condensates bound to that particle. One advantage of these composite particles is that they permit more efficient and increased amounts of polyelectrolytes to be delivered to a target, in comparison to the prior art. Delivery methods include but are not limited to methods whereby the particles are accelerated to a velocity sufficient to penetrate or reach the surface of the target by pneumatic, hydraulic, transferred impulse, macro projectile, centripetal force, explosive, electric discharge, mechanical vibration, magnetic, gravimetric, or electric field. | 10-23-2008 |
