  • Patent number: 11948951
    Abstract: The invention relates to a wide spectrum multi-band detection structure with selective absorption enhancement and its preparation method. The structure comprises a plurality of sub-pixel units capable of detecting incident light in different bands. Each sub-pixel unit is composed of a square well-shaped microstructure array and a metal lower electrode (2), a photosensitive layer (3) and an upper electrode (4) on the surface thereof. The size and array spacing of square well-shaped microstructures in different sub-pixel units are determined according to the detection bands of the sub-pixel units where they are located. The upper openings of the square well-shaped microstructures are hollow to form a resonant cavity, and the adjacent square well-shaped microstructures in the same sub-pixel unit form a resonant cavity, thus solving the problem that the detector structure in the prior art cannot simultaneously realize visible light-near infrared multi-band absorption enhancement detection.

  • Publication number: 20230332261
    Abstract: The present disclosure discloses a method for manufacturing an equal-hardness Cr5 back up roll. The method comprises the following steps: 1) preparing a steel raw material according to chemical components and weight percentage contents in a Cr5 back up roll material, and preparing a steel ingot according to a smelting procedure production process; 2) preparing a roller blank from the steel ingot according to a forging procedure production process; 3) performing thermal treatment on the roller blank; and 4) processing and detecting the roller blank to obtain an equal-hardness forged steel back up roll. The present disclosure solves problems that a hardness, an abrasion resistance, and a contact fatigue of a conventional forged steel back up roll are rapidly reduced in a middle and later use period, and prolongs a comprehensive use period and a service life of the back up roll.

  • Patent number: 8993242
    Abstract: Methods and kits are provided for testing the functional effect of methylating different cytosine residues, for testing patterns of DNA methylation on gene expression, and for site-specific methylation, as well as methylated DNA constructs. Methods are provided that include steps of denaturing a circular double-stranded DNA construct; hybridizing primers to separate strands of the denatured circular DNA construct; contacting the hybridized primers with a DNA polymerase, deoxynucleoside triphosphates, and copies of the primers; contacting nicked copies with a DNA ligase so as to form a copy of the circular DNA construct; contacting the copy of the circular DNA construct with a methyltransferase enzyme; transfecting a cell with C-5 methylated circular DNA construct; and quantifying expression of a gene of interest, thereby determining the effect of C-5 methylating cytosine nucleotide residues of DNA on expression of the gene of interest.

  • Patent number: 8846350
    Abstract: The present invention provides methods and kits for determining which microRNAs bind to a target mRNA where the methods comprise the steps of (a) creating a bait sequence from the target mRNA, where the bait sequence comprises a label that binds to a binding agent; (b) adding a mixture of microRNAs to the bait sequence; (c) separating the microRNAs that bind to the bait sequence from those microRNAs that do not bind; and (d) identifying the microRNAs that bind to the bait sequence, wherein the microRNAs identified are those that bind to the target mRNA.

  • Patent number: 7851154
    Abstract: The present invention relates to a tag-modified bisulfite genomic sequencing (tBGS) method developed for simplified evaluation of DNA methylation sites. The method employs direct cycle sequencing of PCR products at kilobase scale, without conventional DNA fragment cloning. The method entails subjecting bisulfite-modified genomic DNA to a second-round PCR amplification employing GC-tagged primers. The invention also relates to a method for identifying a patient at risk for lung cancer using the tBGS technique disclosed.
