Patents by Inventor Ravi Saxena

Ravi Saxena has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20130251592
    Abstract: An analytical assembly within a unified device structure for integration into an analytical system. The analytical assembly is scalable and includes a plurality of analytical devices, each of which includes a reaction cell, an optical sensor, and at least one optical element positioned in optical communication with both the reaction cell and the sensor and which delivers optical signals from the cell to the sensor. Additional elements are optionally integrated into the analytical assembly. Methods for forming and operating the analytical system are also disclosed.
    Type: Application

  • Publication number: 20130023039
    Abstract: Apparatus, systems and methods for use in analyzing discrete reactions at ultra high multiplex with reduced optical noise, and increased system flexibility. Apparatus include substrates having integrated optical components that increase multiplex capability by one or more of increasing density of reaction regions, improving transmission of light to or collection of light from discrete reactions regions. Integrated optical components include reflective optical elements which re-direct illumination light and light emitted from the discrete regions to more efficiently collect emitted light. Particularly preferred applications include single molecule reaction analysis, such as polymerase mediated template dependent nucleic acid synthesis and sequence determination.

  • Publication number: 20110183409
    Abstract: The invention provides environmental packages, instruments, and methods for sealing, protecting, and providing analysis chips for processing and analysis. The analysis chips are bonded directly or indirectly to chip carriers which are held within the chambers of an environmental packaging strip. The chambers are sealed with a sealing film such that the chip carriers can be extracted using a piercing tool and an extraction tool.
