Expected to develop small medical sensor and light energy conversion materials
[January 6, 2015]
Mechanical Engineering Professor Byeon Jung-hoon (36, photo) developed a new light-reaction nano-substrate manufacturing process technology expected to be used for ultra-small medical sensors or energy conversion materials.
Professor Byeon became the first in the world to configure a light-reaction substrate composed of dots and rings with nano-meter sizes (nm, 1/1 billionth meter) using mechanical processing-based technologies in atmospheric pressure/room temperature conditions. Normally, nano-meter sized metal patterns are configured through a complex lithography process of vacuum conditions used in the semiconductor or display manufacturing process. However, Professor Byeon's study placed nano-particles that attract metal film through the gas flow and temperature control in atmospheric pressure on top of a silicon substrate and additionally induced generation of metal films in room temperature to configure light-reaction substrates patterned with 40 nano-meter level nanodots and nanorings.
The research results are evaluated to have suggested a new alternative to overcome the technological complexities of existing etching processes.
Professor Byeon said "Using the mechanical non-etching process that controls the heat and flow of gases, it was possible to configure light-reaction nano substrates having various properties through nano-particle matter changes and static electricity control of nano-particle surfaces that induce metal film generation." He added, "It will thus be possible to be used to developed ultra-small medical sensors that react to light or as energy conversion materials that change light into heat at small costs."
The results of this study were revealed on December 26 on the <Nanoscale (IF; impact factor 67.39)> website, which has the world's highest authority (top 7.6%) in the nano technology sector published by the Royal Society of Chemistry (RSC) of England under the title 'Aerosol-based soft lithography to fabricate nanoscale silver dots and rings for spectroscopic applications', and will be published this year.
Meanwhile, Professor Byeon has published over 60 studies such as 'gaseous nano particle liquification and substance synthesis', 'gas synthesis using aerosol catalysts', 'organic-inorganic nano complex materials', and 'nano-patterning' in SCI grade international academic journals. In addition to Nanoscale, he is also serving as a reviewer for over 20 international academic journals such as <Angewandte Chemie-International Edition, IF 11.336>, <Small, IF 7.514>, <Chemical Communications, IF 6.718>, etc.
