  • Patent number: 12216981
    Abstract: A system (for generating a layout diagram of a wire routing arrangement) includes a processor and memory including computer program code for one or more programs, the system generating the layout diagram including: placing, relative to a given one of masks in a multi-patterning context, a given cut pattern at a first candidate location over a corresponding portion of a given conductive pattern in a metallization layer; determining that the first candidate location results in an intra-row non-circular group of a given row which violates a design rule, the intra-row non-circular group including first and second cut patterns which abut a same boundary of the given row, and a total number of cut patterns in the being an even number; and temporarily preventing placement of the given cut pattern in the metallization layer at the first candidate location until a correction is made which avoids violating the design rule.

  • Patent number: 11214840
    Abstract: Provided herein are aptamers that bind specifically to the surface proteins of periodontal pathogens. Also provided herein are methods for detecting and treating periodontal disease in a subject. The method comprises detecting bacteria associated with periodontal disease by use of the present aptamers to analyze a sample taken from a gum pocket of a tooth of the subject; and treating the periodontal disease of the subject by administering to the gum pocket of the tooth a bactericide or an anti-microbial phototherapy to eradicate the bacteria associated with periodontal disease.

  • Publication number: 20080299047
    Abstract: The present invention relates to a process for preparing water-soluble and dispersed iron oxide (Fe3O4) nanoparticles and application thereof, characterized in which two-stage additions of protective agent and chemical co-precipitation are employed in the process. In the first stage, Fe3O4 nanoparticles are obtained using absorbent-reactant coexistence technology. In the second stage, proper amount of adherent is added to cover the nanoparticle surface entirely. The resulting water-soluble and dispersed Fe3O4 nanoparticles can easily bind with thiols or biomolecules, such as nucleic acid and peptide. The Fe3O4 nanoparticles of the present invention may be used as magnetic resonance imaging contrast agent and used in magnetic guiding related biomolecular technologies for clinical testing, diagnosis and treatment.
