A method of fabricating a microarray including the steps of: (a) contacting a substrate having wells with a reagent reactive with said substrate to produce a surface modification within said wells and a surface modification surrounding said wells; (b) polishing said substrate to produce a polished surface modification surrounding said wells, wherein said surface modification surrounding said wells is removed and said surface modification within said wells is retained, and (c) depositing a biopolymer onto said substrate, wherein different affinities of said surface modification within said wells and said polished surface facilitate localization of said biopolymer within said wells.

Microvessels, microparticles, and methods of manufacturing and using the same

Disclosed herein are methods of method of making a substrate for performing a chemical synthesis reaction.

Methods of forming and using a solid-phase support

An electroosmotic (EO) pump is provided that includes a housing having a pump cavity, a porous core medium and electrodes. The porous core medium is positioned within the pump cavity to form an exterior reservoir that extends at least partially about an exterior surface of the porous core medium. The porous core medium has an open inner chamber provided therein. The inner chamber represents an interior reservoir. The electrodes are positioned in the inner chamber and are positioned proximate the exterior surface. The electrodes induce flow of a fluid through the porous core medium between the interior and exterior reservoirs, wherein a gas is generated when the electrodes induce flow of the fluid. The housing has a fluid inlet to convey the fluid to one of the interior reservoir and the exterior reservoir. The housing has a fluid outlet to discharge the fluid from another of the interior reservoir and the exterior reservoir. The housing has a gas removal device to remove the gas from the pump cavity.

System or device for biochemical analysis having at least one electroosmotic pump

Described is a system and method for synthesizing polymeric molecules such as oligonucleotides and polypeptides. The system is capable of continuously synthesizing molecules by providing an array of reaction sites and an array of stations for carrying out synthetic manipulations. The reaction sites in the former array can be placed in a fixed order and at fixed intervals relative to each other. Similarly, the stations can be placed in a fixed order and at fixed intervals relative to each other. The two arrays can be moved relative to each other such that the stations carry out desired steps of a reaction scheme at each reaction site. The relative locations of the stations and the schedule for the relative movement can correlate with the order and duration of reaction steps in the reaction scheme such that once a reaction site has completed a cycle of interacting with the full array of stations then the reaction scheme is complete.
