NanoInk of Chicago has received US Patent No. 7,762,638, "Methods and apparatus for ink delivery to nanolithographic probe systems." The patent claims an ink-delivery device for direct-write nanolithographic printing of inks with use of a tip or tip array. The tip array includes ink reservoirs, microfluidic channels connected to the ink reservoirs; and dipping wells connected to the microfluidic channels, where the dipping wells have a geometry for dipping the tip or tip array into the dipping wells. The patent also claims a method of creating an array of inked probes for performing direct-write nanolithographic printing.
Samsung Electronics has received US Patent No. 7,763,424, "Method of removing air bubbles from hybridization solution of microarray-coverslip assembly and microarray kit for the same." The patent claims method of removing air bubbles from a hybridization solution in a microarray. According to the patent, the method includes injecting a solution of magnetic particles between the coverslip and microarray, applying a magnetic field to the microarray-coverslip assembly, moving the magnetic particles, and removing air bubbles in the hybridization solution from a hybridization area of the microarray with the magnetic particles.
Northwestern University of Evanston, Ill., has received US Patent No. 7,764,361, "Systems and methods to analyze multiplexed bead-based assays using backscattered light." The patent describes an epifluorescence microscope-based optical system that is equipped with a tunable filter to localize microspheres in bead-based assays based on a back-scattered light image. According to the patent, a common optical path for reflected and emitted luminescence in conjunction with a tunable filter negates the requirement of an additional sensor employed in existing technologies for localizing microspheres based on light scatter measurements.
