Studies in the Area of Applied Surface Science Reported from Seoul National University (Fabrication of nanopore on pyramid)

August 15, 2014



By a News Reporter-Staff News Editor at Science Letter -- Researchers detail new data in Science. According to news reporting originating from Seoul, South Korea, by NewsRx correspondents, research stated, "There have been tremendous interests about the fabrication of metallic nanopore due to the ultrafast genome sequencing biosensor capability. In this report, the fabrication of the nanopore on the Au coated SiO2 pyramid has been examined using various high energy electron beam irradiation and focused ion beam (FIB) milling techniques."

Our news editors obtained a quote from the research from Seoul National University, "The microfabricated Au nano-apertures on pyramid were irradiated with various high energy electron beam and FIB techniques. The formation of the nanopore dependent on the probe current was also examined using electron probe micro-analysis (EPMA). The nanopore on the Au coated SiO2 pyramid is found to be an Au Si mixture. The Au nanopore on the crater type hole was also fabricated using FIB Ga ion beam scanning."

According to the news editors, the research concluded: "The shrinking rate was found to be the fastest compared with those fabricated with the other electron beam techniques."
