Nanoantenna arrays power a new generation of fluorescence-based sensors

Mon, 16 Oct 17 00:03:00 -0700

Researchers from the Universities of Bristol and Bedfordshire, in collaboration with multinational company ABB, have designed and tested a series of plasmonic nanoantenna arrays that could lead to the development of a new generation of ultrasensitive and low-cost fluorescence sensors that could be used to monitor water quality.

Nanoimprinted hyperlens array: Paving the way for practical super-resolution imaging

Fri, 21 Apr 17 00:06:40 -0700

Research conducted by Professor Junsuk Rho's team at POSTECH, South Korea, has demonstrated a scalable and reliable fabrication process of a large scale hyperlens device based on direct pattern transfer techniques. The research team's new cost-effective fabrication method can be used to proliferate practical far-field and real-time super-resolution imaging devices that can be widely used in optics, biology, medical science, nanotechnology, and other related interdisciplinary fields. This achievement has been published in Scientific Reports.

With simple process, UW-Madison engineers fabricate fastest flexible silicon transistor

Wed, 20 Apr 16 00:08:20 -0700

One secret to creating the world's fastest silicon-based flexible transistors: a very, very tiny knife. Working in collaboration with colleagues around the country, University of Wisconsin-Madison engineers have pioneered a unique method that could allow manufacturers to easily and cheaply fabricate high-performance transistors with wireless capabilities on huge rolls of flexible plastic.

Insect wings inspire antibacterial surfaces for corneal transplants, other medical devices
Someday, cicadas and dragonflies might save your sight. The key to this power lies in their wings, which are coated with a forest of tiny pointed pillars that impale and kill bacterial cells unlucky enough to land on them. Now, scientists report they have replicated these antibacterial nanopillars on synthetic polymers that are being developed to restore vision. The researchers present their work at the 251st National Meeting
