A method and apparatus for imaging a sample are provided. An electromagnetic radiation source generates excitation radiation which is sized by excitation optics to a line. The line is directed at a sample resting on a support and excites a plurality of regions on the sample. Collection optics collect response radiation reflected from the sample I and image the reflected radiation. A detector senses the reflected radiation and is positioned to permit discrimination between radiation reflected from a certain focal plane in the sample and certain other planes within the sample.

The present invention provides an array of polymers and methods of forming arrays of polymers by providing a substrate having a first layer including one or more dielectric coatings on a solid support and a second layer including a plurality of polymers disposed on the first layer. The invention also provides methods for forming an array of polymers on a substrate using light-directed synthesis by providing a substrate having a first layer including one or more dielectric coatings on a solid support; derivatizing the first layer by contacting the first layer with a silanation reagent, and a second layer disposed on said first layer wherein the second layer includes functional groups protected with a photolabile protecting group.
摘要:
The present invention provides methods to reduce bleed-over of transmitted light through a photolithographic mask during photolysis by reducing the gap between the mask and the substrate upon which photolithography is being performed. In a preferred embodiment of the invention, a leveling method in combination with a compressed gas is used to significantly reduce the gap during the photolithography process and to provide increased photolithographic contrast and resolution.

In accordance with various embodiments of the invention, an apparatus is provided for hybridizing a nucleic acid microarray immobilized on a surface of a solid substrate. The apparatus comprises at least one assembly for securing the solid substrate during hybridization, the assembly comprising a carrier and a cover having a surface facing the carrier. The carrier and the cover can be dimensioned to receive the solid substrate between the carrier and the surface of the cover so that the surfaces of the cover and the solid substrate define a cavity. In some embodiments, the apparatus can include a fluid control module comprising a manifold, at least one liquid reservoir, at least one waste container, and a vacuum source in fluid communication with the waste container. The manifold can provide fluid communication between the liquid reservoir and the cavity and between the cavity and the waste container, and the vacuum source can provide a pressure difference between the liquid reservoir and the waste container. The apparatus can further include at least one thermal management module for controlling temperature of the nucleic acid microarray immobilized on the surface of the solid substrate, and the thermal management module thermally can contact the assembly; and a pulse valve in fluid communication with the cavity, the pulse valve adapted to agitate fluid within the cavity.
