    摘要: A method for controlling a focus of an optical system. The method includes providing a pair of incident light beams to a conjugate lens. The incident light beams are directed by the lens to converge toward a focal region. The method also includes reflecting the incident light beams with an object positioned proximate to the focal region. The reflected light beams return to and propagate through the lens. The method also includes determining relative separation measured between the reflected light beams and determining a degree-of-focus of the optical system with respect to the sample based upon the relative separation.

    摘要: 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.

    摘要: A flow cell for use in a microfluidic detection system is provided. The flow cell includes a flow cell body having a channel that is configured to convey a solution through the flow cell body. The flow cell also includes a bottom surface and a top surface. The bottom surface is configured to be removably held by the detection system, and the top surface is transparent and permits light to pass therethrough. The flow cell body also includes fluidic inlet and outlet ports that are in fluid communication with the channel. A pump cavity is also provided in the flow cell body. The pump cavity fluidly communicates with, and is interposed between, an end of the channel and one of the fluidic inlet and outlet ports. An electroosmotic (EO) pump is held in the pump cavity. The EO pump induces flow of the solution through the EO pump and channel between the fluidic inlet and outlet ports.

    摘要: A system and method for imaging biological samples on multiple surfaces of a support structure are disclosed. The support structure may be a flow cell through which a reagent fluid is allowed to flow and interact with the biological samples. Excitation radiation from at least one radiation source may be used to excite the biological samples on multiple surfaces. In this manner, fluorescent emission radiation may be generated from the biological samples and subsequently captured and detected by detection optics and at least one detector. The detected fluorescent emission radiation may then be used to generate image data. This imaging of multiple surfaces may be accomplished either sequentially or simultaneously. In addition, the techniques of the present invention may be used with any type of imaging system. For instance, both epifluorescent and total internal reflection methods may benefit from the techniques of the present invention.
