  • Publication number: 20140355179
    Abstract: A portable electronic device housing portion is applied to a cover glass. The cover glass is heated to generate ionic conductivity therein and the method includes anodic bonding the cover glass to the housing portion. Cooling the assembly induces compressive stress within the cover glass to increase its tensile strength. The process which seals the cover glass to the housing also strengthens the cover glass.

  • Patent number: 7687256
    Abstract: The present invention provides substrates having a plurality of micro-locations on its surface. Each micro-location has an effective dose of an ion beam treatment such that the plurality of the micro-locations exhibit an affinity to a compound that is different from the affinity of the remainder of the substrate surface to that compound. The substrates of the invention can be utilized to form microarrays of biological molecules, such as oligonucleotides or peptides. Such microarrays can find a variety of applications. For example, they can be employed in large scale hybridization assays in many genetic applications, such as mapping of genomes, monitoring of gene expression, DNA sequencing, genetic diagnosis, and genotyping of organisms.

  • Patent number: 6964948
    Abstract: The present invention relates generally to small peptide-based constructs, including derivatized constructs, and their therapeutic uses. The constructs and derivatized constructs can have at least one of heparin binding, heparin neutralizing, endothelial cell proliferation inhibiting, antiangiogenic, LPS binding, LPS neutralization, or antimicrobial properties. The sequences of these constructs are based on a reverse subsequence derived from Domain II of bactericidal/permeability-increasing protein (BPI).

  • Publication number: 20040101861
    Abstract: The present invention provides a microarray having a plurality of micro-locations for confining selected photophores, for example, biological molecules exhibiting fluorescence spectra. The microarray can further include an array of optoelectronic photodetectors each of which is optically coupled with at least one of the micro-locations to detect radiation, for example, fluorescence radiation, that is emitted from the photophores confined in that micro-location. Each photodetector includes a resonant cavity that is formed of a front reflector and/or a back reflector having distributed Bragg reflector structures and a photo-detecting element disposed in the resonant cavity. The microarray can utilize either external optical excitation sources, such as lasers, LEDs, or can contain its own excitation sources in an integrated structure containing both optical radiation emitters, such as, vertical cavity surface emitting lasers or resonant cavity LEDs, and resonant cavity photodetectors.
