Applied Biosystems has received US Patent No. 7,547,096, "Apparatus and methods of depositing fluid." The patent claims a printing device for depositing fluid for chemical and biological analysis on a support. The device includes: a) a number of adjoining plates, where each plate includes a first surface and a second surface; b) a number of channels that intersect the first and second surface of each plate; c) and a number of deposition units formed from a solid material designed to produce an array of positionally distinguishable areas.

The Van Andel Research Institute of Grand Rapids, Mich., has received US Patent No. 7,547,424, "Method and apparatus for making partitioned slides." The patent describes an apparatus for placing a hydrophobic barrier on an examination slide. The apparatus includes a vessel, a printer block capable of forming a hydrophobic barrier on the examination slide in a specified pattern, a slide holder, and a reversible actuator. A method for placing a hydrophobic barrier on an examination slide in a specified pattern is also claimed.

Purdue Research Foundation of West Lafayette, Ind., has received US Patent No. 7,547,526, "Cell concentration and pathogen recovery." The patent claims a method for the concentration and recovery of viable microorganisms from a sample. The method includes: a) providing a microorganism-containing sample with a liquid component; (b) providing a hollow fiber filter; c) reducing the liquid component by applying the sample to the hollow fiber filter; d) back flushing the microorganisms from the hollow fiber filter in a buffer; e) delivering the microorganisms to a biochip device; and f) detecting their presence.

The Massachusetts Institute of Technology has received US Patent No. 7,547,556, "Methods for filling a sample array by droplet dragging." The patent claims a method and an array filling system for loading disparate sample containers. According to the patent abstract, each receptacle is characterized by a hydrophilic surface, and the receptacles are separated by a hydrophobic surface. The system has a liquid transfer device capable of holding liquid and adapted for motion to cause sequential communication of the liquid held with the successive receptacles of the array by dragging the liquid across the hydrophobic surface, according to the abstract.

Enzo Life Sciences of Farmingdale, NY, has received US Patent No. 7,547,772, "Chimeric nucleic acid constructs and compositions comprising sets of nucleic acid constructs." The patent provides compositions for use in real-time nucleic acid detection processes. These processes are carried out with energy transfer elements attached to nucleic acid primers, nucleotides, nucleic acid probes, or nucleic-acid-binding agents. Real-time nucleic acid detection allows for the qualitative or quantitative detection or determination of single-stranded or double-stranded nucleic acids of interest in a sample, according to the patent abstract.
