  • Publication number: 20210277048
    Abstract: The present invention relates to a method of preparing nucleic acid-inorganic hybrid nanoflowers, which comprises allowing a nucleic acid to react with a solution of a metal ion-containing compound at room temperature, thereby forming a complex between the metal ion and the nitrogen atom of an amide bond or amine group present in the nucleic acid. According to the present invention, organic-inorganic hybrid nanoflower structures may be synthesized using nucleic acid in a simple manner under an environmentally friendly condition without any toxic chemical substance. The produced organic-inorganic hybrid nanoflower structures show a high DNA encapsulation yield, have resistance against nuclease, and show significantly increased peroxidase activity. Thus, these nanoflower structures may be widely used as a gene therapy carrier and in biosensing technology.

  • Publication number: 20120322216
    Abstract: Disclosed is a method for reducing poly-depletion in a dual gate CMOS fabrication process. The method reduces the poly-depletion in a dual gate CMOS fabrication process by increasing the doping efficiency in a gate polysilicon film. In order to increase the doping efficiency, the method employs the following four technical principles. First, the doping efficiency is increased when the dose of N+ ion implantation is increased. Second, the doping efficiency is increased when the thickness of N+ polysilicon is reduced. Third, the increase of depletion caused by the reduction of the channel width is inhibited when the EFH is adjusted to be less than 0. Fourth, the overall doping efficiency is increased when each step of polysilicon deposition and ion implantation is divided into multiple steps.
