Roche NimbleGen of Madison, Wis., has received US Patent No. 8,026,094, "Microarray synthesis instrument and method." During the illumination period of a monomer-addition cycle in synthesizing a DNA microarray, undesirable reflections may reduce the light-dark contrast and negatively affect the precision and resolution of the microarray synthesis, according to the inventors. This patent provides a flow cell that reduces the undesired reflections by constructing certain flow cell structures with materials that have similar refractive indexes as that of the solution that is in the oligomer synthesis chamber during the illumination period.

Roche NimbleGen has also received US Patent No. 8,030,056, "Substrate patterning using a digital optical chemistry micromirror imager." An apparatus for catalyzing a reaction on a substrate is claimed. It includes a light source, a micromirror positioned to redirect light from the light source toward a substrate, where the redirected light catalyzes a chemical reaction. A computer is also claimed that connects to and controls the positioning of mirrors within the micromirror to specifically redirect light to specific portions of a substrate. The substrate can be placed in a reaction chamber, where the light that is redirected by the micromirror catalyzes a chemical reaction.

Zbigniew Lesnikowski and Agnieszka Olejniczak of Lodz, Poland, have received US Patent No. 8,026,348, "Nucleoside derivative, modified oligonucleotide, method for their synthesis and applications thereof." Methods of preparing carboranes and metallacarboranes, both of which can be used as electrochemically active labels for biological compounds, are disclosed. Nucleic acid derivatives labeled with carborane or metallacarborane can be detected by electrochemical methods and can find several practical applications, such as materials for nanoconstruction, in DNA array technology or for the construction of biosensors, especially electrochemical biosensors, according to the inventors.

Tufts University of Medford, Mass., has received US Patent No. 8,030,094, "Self-encoding sensor with microspheres." A microsphere-based analytic chemistry system is described in which self-encoding microspheres having distinct optical response signatures to specific target analytes may be mixed together while the ability is retained to identify the sensor type and location of each sensor in a random dispersion of large numbers of such sensors in a sensor array using an optically interrogatable encoding scheme. An optical fiber bundle sensor is also disclosed in which individual microsphere sensors are disposed in microwells at a distal end of the fiber bundle and are optically coupled to discrete fibers or groups of fibers within the bundle. The identities of the individual sensors in the array are self-encoded by exposing the array to a reference analyte while illuminating the array with excitation light energy. A single sensor array may carry thousands of discrete sensing elements whose combined signal provides for substantial improvements in sensor detection limits, response times, and signal-to-noise ratios, according to the inventors.
