Scientists develop easy, cost-effective way to produce hyperlens
POHANG, South Korea, April 21 (Yonhap) -- A group of South Korean scientists have developed a method to manufacture large scale hyperlens devices based on the direct pattern transfer technique, Pohang University of Science and Technology (POSTECH) said Friday.
Hyperlense is a super-resolution device, but they suffer from extremely small observation area. A hyperlens array has been considered to be a solution, but fabrication of such an array would be extremely difficult and expensive.
The team led by Rho Jun-suk at POSTECH in collaboration with a research team from Korea University said this obstacle has been overcome through a scalable and reliable fabrication process called nanoimprint lithography.
Rho anticipates that the research team's new cost-effective fabrication method can be used to proliferate practical real-time super-resolution imaging devices that can be widely used in optics and medical science, and other related interdisciplinary fields.
This research was supported by the National Research Foundation of Korea and was funded by the Ministry of Science, ICT and Future Planning. The findings were published in the journal "Scientific Reports."
