University of Illinois at Urbana-Champaign News
Low-Power Nanotweezers May Benefit Cell Studies
URBANA-CHAMPAIGN, Ill., Oct. 1, 2012 — Low-power optical tweezers can trap, manipulate and analyze nanoparticles — including delicate biological samples — new work demonstrates.
Special optoelectronic properties make 3-D photonic crystals shine
CHAMPAIGN, Ill. – A newly demonstrated 3-D photonic crystal with exceptional optical and electrical properties will open new avenues for solar cells, metamaterials, lasers and more. “For many years, people have demonstrated 3-D photonic crystals with...
Synchrotron enables faster, better tissue imaging
MILWAUKEE – A synchrotron-based imaging technique delivers intensity a million times brighter than sunlight – and offers high-resolution pictures of the molecular composition of tissues with high speed and quality. A team of researchers from the...
Synchrotron-Based Tissue Imaging
MILWAUKEE, March 28, 2011 — With intensity a million times brighter than sunlight, a new synchrotron-based imaging technique offers high-resolution pictures of the molecular composition of tissues with unprecedented speed and quality. Carol Hirschmugl, a physicist at the...
DTU, UIUC Collaborating on Fiber Lasers
LYNGBY, Denmark, Oct. 20, 2010 — DTU Fotonik Department of Photonics Engineering at the Technical University of Denmark and the University of Illinois at Urbana-Champaign (UIUC) are partnering to develop a multicolor femtosecond all-fiber laser for biophotonics applications.
A Leap for Lasers and Photodetectors
TEMPE, Ariz., Aug. 10, 2010 — A team of Arizona State University researchers will get support from the US Department of Defense to aid development of the next generations of lasers and infrared photodetectors. The technology is widely employed in sensing and imaging for an...
Edible Optics, Implantable Electronics
MEDFORD, Mass., Aug. 11, 2010 — A decade of research has yielded new uses for an ancient material – silk fibers. Thanks to their amazing mechanical properties as well as their looks, silk fibers have been important materials in textiles, medical sutures, and even armor for...
Nanocircuit Created on Graphene
ATLANTA, Ga., June 16, 2010 — Scientists have made a breakthrough toward creating nanocircuitry on graphene, which is widely regarded as the most promising candidate to replace silicon as the building block of transistors. The group has devised a simple and quick one-step...
Optical microrings boost cancer detection
URBANA-CHAMPAIGN, Ill. – Sensitive detection of biomolecules is of great interest for applications such as drug development, virus detection, environmental monitoring and medical diagnostics. In contrast to optical biosensors based on surface plasmon resonance,...
Self-Assembled Nanowires
CHAMPAIGN, Ill., April 21, 2009 – Researchers at the University of Illinois created the first metal-semiconductor field-effect transistor fabricated with a self-assembled, planar gallium-arsenide nanowire channel to make such transistors smaller and faster.
Bright Quantum Dot Record Set
CHAMPAIGN, Ill., Sept. 25, 2007 -- Enhanced fluorescence intensity has been demonstrated by a factor of up to 108 by placing quantum dots on a specially designed photonic crystal. Potential applications include high-brightness LEDs, optical switches and personalized, high-sensitivity...
Algorithms Accelerate CAT Scans
May 19, 2005 — URBANA, Ill., May 19 -- Researchers at InstaRecon said computed tomography (CT) scanning systems will get a big boost in accuracy and speed thanks to mathematical methods it developed that can provide nearly instantaneous, real-time reconstruction...
Single-Bubble Cavitation Spectra Indicate Plasma Formation
Apr 1, 2005 — Experimental investigations into the spectra of sonoluminescence have offered evidence to support the existence of a plasma core during the implosive collapse of bubbles in liquids irradiated with ultrasound. Kenneth S. Suslick and David J....
DARPA Funds Photonics Center
Jun 22, 2004 — CHAMPAIGN, Ill., June 22 -- The University of Illinois (UI) at Urbana-Champaign has received a grant from the Defense Advanced Research Projects Agency (DARPA) to create a photonics research center to develop ultrafast light sources for high-speed...
