  • Patent number: 9005852
    Abstract: During a calculation technique, a modification to a reflective photo-mask is calculated. In particular, using information specifying a defect associated with a location on a top surface of the reflective photo-mask, the modification to the reflective photo-mask is calculated. For example, the calculation may involve an inverse optical calculation in which a difference between a pattern associated with the reflective photo-mask at an image plane in a photo-lithographic process and a reference pattern at the image plane in the photo-lithographic process is used to calculate the modification at an object plane in the photo-lithographic process. Note that the modification includes a material added to the top surface of the reflective photo-mask using an additive fabrication process. Moreover, the modification is proximate to the location.

  • Patent number: 9005854
    Abstract: A conductive pattern is formed using a reactive polymer comprising pendant tertiary alkyl ester groups, a compound that provides an acid upon exposure to radiation, and a crosslinking agent. A polymeric layer is patternwise exposed to form first exposed regions with a polymer comprising carboxylic acid groups that are contacted with electroless seed metal ions, and then contacted with a halide to form corresponding electroless seed metal halide. Another exposure converts electroless seed metal halide to electroless seed metal nuclei and forms second exposed regions. A reducing agent is used to develop the electroless seed metal nuclei in the second exposed regions, or to develop the electroless seed metal halide in the first exposed regions. Fixing is used to remove any remaining electroless seed metal halide. The electroless seed metal nuclei are then electrolessly plated in various exposed regions.

  • Patent number: 9005887
    Abstract: There is provided mechanisms for the detection of an analyte in a sample. The mechanisms utilize at least a first measurement channel comprising a detection reactant corresponding to the analyte to be detected, and at least a microstructure associated with the first measurement channel. When the mechanisms are in use, the sample is introduced into the first measurement channel and propagated by way of the first measurement channel towards the microstructure. If the analyte is present in the sample, the analyte interacts with the detection reactant to form a networked product, and the microstructure is configured to filter the networked product.

  • Patent number: 9005888
    Abstract: The invention relates to compositions and methods for isolation of microvesicles produced by mammalian cells. These microvesicles, known as extracellular microvesicles or circulating microvesicles, are isolated from sample materials such as body fluids, or from cell culture media that has been used to culture and maintain mammalian cells in vitro. The isolation of microvesicles as described herein results in purification and concentration of the microvesicles. The invention also provides related methods for producing blood serum and/or blood plasma that is free of detectable microvesicles, largely depleted of microvesicles, or has reduced concentration of microvesicles compared to the blood serum or blood plasma starting material (collectively termed “microvesicle-depleted”).

  • Patent number: 9005890
    Abstract: Metal enhanced luminescence using alloy nanoparticles offers additional degrees of freedom for tuning their optical properties by altering atomic composition and atomic arrangement when compared to pure metal nanoparticles such as gold and silver. Surface plasmon resonance wavelengths of silver-copper nanoparticles were tuned in the visible and near infrared region by changing annealing temperature. Strong emission enhancement of luminophores at the vicinity of the Ag—Cu nanoparticles was shown when the SPR spectrum was tuned to produce maximum spectral overlap. As the SPR spectrum can be easily tailored, this platform can be effectively used to enhance luminescence of different luminophores.

    Abstract: We disclose a method comprising: (a) providing an embryonic stem (ES) cell; and (b) establishing a progenitor cell line from the embryonic stem cell; in which the progenitor cell line is selected based on its ability to self-renew. Preferably, the method selects against somatic cells based on their inability to self-renew. Preferably, the progenitor cell line is derived or established in the absence of co-culture, preferably in the absence of feeder cells, which preferably selects against embryonic stem cells. Optionally, the method comprises (d) deriving a differentiated cell from the progenitor cell line.
