Laser-Driven Nanobubbles Noninvasively Detect Malaria
HOUSTON, Jan. 2, 2014 — A noninvasive, laser scanner “vapor nanobubble” technology using no dyes or diagnostic chemicals can detect even a single malaria-infected cell among a million normal cells, with zero false-positive readings. The transdermal diagnostic method, which recently completed its first preclinical tests at Rice University, takes advantage of the optical properties and nanosize of hemozoin, a nanoparticle produced by a malaria parasite inside infected red blood cells. The technology uses...
A BOLD idea for handling big data
HOUSTON – An optical network in development will help streamline demanding, data-intensive computations in a customized, energy-efficient way. The new network, BOLD (Big Data and Optical Lightpaths-Driven Networked Systems Research Infrastructure), will use...
More Funding Brings Daylight Solutions’ Imager Closer to Market
SAN DIEGO, Oct. 1, 2013 — Daylight Solutions Inc. has been awarded additional funding from the National Science Foundation (NSF) to accelerate the transition of its mid-infrared hyperspectral imaging platform into commercial markets, the company announced Monday. Daylight...
Photodetector discerns polarized light intrinsically
HOUSTON, and LIVERMORE, Calif. – Few photodetector materials can discern polarized light directly without a grate or a filter, but a newly created carbon-based broadband photodetector demonstrates intrinsic polarimetry. A team from Rice University and Sandia National Laboratories...
A BOLD Idea for Handling ‘Big Data’
HOUSTON, Sept. 23, 2013 — A new optical network being developed at Rice University will help streamline demanding, data-intensive computations in a customized, energy-efficient way. The new network, BOLD — short for Big Data and Optical Lightpaths-Driven Networked...
Nonlinear media controls light with light
HOUSTON – A variety of nonlinear media, each with tailored optical properties, could be produced using a gold-disk patterning method to perform four-wave mixing. Developed at Rice University, the method is the first to produce materials that can achieve...
Solar Steam Sterilizes with Sunlight
HOUSTON, July 24, 2013 — A “solar steam” sterilization system that uses light-harvesting nanoparticles to convert as much as 80 percent of sunlight energy into germ-killing heat could be a boon for more than 2.5 billion people who lack adequate sanitation.
Photodetector Discerns Polarized Light Intrinsically
HOUSTON & LIVERMORE, Calif., July 18, 2013 — Few photodetector materials can discern polarized light — individual electromagnetic waves oscillating parallel to one another — directly without the use of a grate or a filter. For a newly created carbon-based broadband photodetector, however,...
Future Looks Sunny for Organic Polymers
HOUSTON, and UNIVERSITY PARK, Pa., May 30, 2013 — Solar cells based on block copolymers, self-assembling organic materials that arrange themselves in distinct layers, could pave the way for a new class of solar energy devices.
Controlling Light … with Light
HOUSTON, May 22, 2013 — Gold nanoparticles arranged into geometric patterns can control incoming light with light via a four-wave mixing process, transforming its output into a different color, Rice University theoretical and applied physicists say. The technique could be...
Carbon nanotube detector works in the infrared at room temperature
HOUSTON – A photodetector that uses carbon nanotube films of varying widths can gather light in and beyond visible wavelengths, a finding that promises to make possible a unique set of optoelectronic devices, solar cells and maybe even specialized cameras....
Thermal Imaging Helps Nab Bombing Suspect
WATERTOWN, Mass., April 22, 2013 — The photonic technology of thermal imaging was literally in the spotlight on the evening of April 19 as law enforcement officials used it to monitor and capture suspected Boston Marathon bomber Dzhokhar Tsarnaev. On April 15, two bombs exploded in...
Nanotube Detector a Promising Optoelectronic Device
HOUSTON, Feb. 28, 2013 — A nanotube-based photodetector that gathers light in and beyond visible wavelengths promises to make possible a unique set of optoelectronic devices, solar cells and maybe even specialized cameras.
Lasers Tune Common Nanoparticles to Near-IR Wavelengths
HOUSTON, Jan. 4, 2013 — Diverse types of ordinary nanoparticles can be selectively heated on demand by short laser pulses at near-infrared wavelengths. The technique could advance the use of these particles in medical and industrial applications.
Nanobubbles Destroy Some Cells, Treat Others
HOUSTON, Dec. 4, 2012 — A single laser blast can activate plasmonic nanobubbles that selectively kill diseased cells while at the same time treating others, and leaving neighboring healthy cells untouched.
Antenna on a Chip Zips Through 3-D ‘Free Space’
HOUSTON, Nov. 21, 2012 — A new micron-scale spatial light modulator (SLM) works in 3-D “free space” and runs orders of magnitude faster than those used in sensing and imaging devices, and it holds great potential for imaging, display, holographic, measurement and remote...
Photonic Nanocrystals Convert Sunlight to Solar Steam
HOUSTON, Nov. 20, 2012 — Light-capturing nanoparticles so efficient at turning sunlight into heat have been shown to produce solar steam from nearly frozen water. Inventors of the new technology expect its first uses to be for sanitation and water purification in developing...
Plasmonics Promising for Optically Induced Electronics
HOUSTON, Oct. 12, 2012 — Nanoscale plasmonic antennas, or nonamers, attached to graphene could theoretically create on-demand electronic circuits by hitting them with light at particular frequencies.
Photonic Gel a Metamaterial with Myriad Uses
HOUSTON and CAMBRIDGE, Mass., Oct. 11, 2012 — Thin films that change color under certain conditions and are incredibly cheap to make may inform future multiband optical elements in laser-driven systems or high-contrast displays, among other applications.
Tkaczyk Wins Norman Edmund Inspiration Award
BARRINGTON, N.J., Oct. 10, 2012 — Tomasz Tkaczyk of Rice University has won the 2012 Norman Edmund Inspiration Award for his low-cost, portable optical system for global health applications, the optical components maker announced Wednesday.
Spectroscopy Optimizes Fluorescent Probes for DNA Study
HOUSTON, Sept. 7, 2012 — Time-resolved spectroscopy plus careful calculations can optimize photoluminescent probes for studying DNA, with results nearly twice as good as standard fluorescence spectroscopy for specific sequences, according to a new paper from Rice...
Plasmonic Chains Act Like Polymers
HOUSTON, July 16, 2012 — New research that seeks to establish points of reference between plasmonic particles and polymers might lead to smaller computer chips, better antennae and improvements in optical computing.
Fluorescing Paint Detects Stress, Strain
HOUSTON, June 25, 2012 — A new type of paint made with fluorescing carbon nanotubes can help detect structural stress and strain remotely, say scientists at Rice University.It provides a big advantage over conventional strain gauges, which must be physically connected to...
Texas A&M Hosting Bio-Optics Conference
COLLEGE STATION, Texas, May 18, 2012 — The inaugural BioMedOpTex Symposium will take place May 23-25 at the Annenberg Presidential Conference Center at the George Bush Presidential Library.
Hidden 3-D objects imaged
CAMBRIDGE, Mass. – A new ultrafast time-of-flight imaging technique uses reflections from a nonmirrored surface to recover 3-D shapes hidden from sight, essentially allowing the camera to capture images around corners. Scientists at MIT’s Media Lab...
