  • Publication number: 20210214718
    Abstract: The present invention relates to a method of enriching pathogens and extracting nucleic acids using diatomaceous earth functionalized with amines and dimethyl suberimidate as a crosslinking agent, wherein negatively charged pathogens are electrically absorbed on the surface of positively charged diatomaceous earth by the crosslinking agent, and nucleic acid released after cell lysis can be immobilized and separated on the diatomaceous earth through reversible crosslinking with amine groups of diatomaceous earth. The above method can be used as a point-of-care testing because it is possible to concentrate pathogens and extract nucleic acids at the same time as an all-in-one device without the use of special equipment and electricity (electric power), and it is superior in time and cost savings than the conventional method, and the extracted nucleic acid has an advantage that can be usefully used for diagnosis and treatment of the diseases.

  • Publication number: 20210184062
    Abstract: Disclosed herein is an automotive solar cell roof panel which may be manufactured by adjusting the width and number of cells according to a transparent part and an opaque part in one solar cell module, thus improving output and simplifying a structure. The first and second solar cells include a plurality of transparent-part cells and a plurality of opaque-part cells whose widths and numbers are adjusted according to a current density and a voltage ratio. As such, it is unnecessary to array different kinds of solar cells with different voltage or current ranges, thus maximizing output in one solar cell module, and an additional wiring structure for individually controlling output power, an additional converter, and additional control for voltage matching may not be required, thus simplifying a process.
