Nanoparticle-Laser Method Targets Chemo Drugs
HOUSTON, April 10, 2012 — A potential treatment method for drug-resistant cancer uses gold nanoparticles to convert laser energy into “plasmonic nanobubbles,” which allow chemotherapy drugs to enter single cells. Delivering chemotherapy with nanobubbles is 30 times more deadly than traditional drug treatment with less than one-tenth the clinical dose, a study out of Rice University has found.
Nanostars Seen as Superior for SERS
HOUSTON, March 29, 2012 — Synthesized starfruit-shaped gold nanorods could strengthen applications that rely on surface-enhanced Raman spectroscopy.
Laser-assisted Camera Images Around Corners
CAMBRIDGE, Mass., March 21, 2012 — Using reflections from a non-mirrored surface, a new ultrafast time-of-flight imaging technique recovers 3-D shapes hidden from sight, essentially allowing the camera to capture images around corners.

Light from Nanoparticles Controlled
HOUSTON, Oct. 3, 2011 — Rice University researchers have created a technique to control plasmonic scattering from gold nanoparticles using liquid crystals. The researchers use voltage to sensitively manipulate the alignment of liquid crystal molecules that alternately...
Hybrid graphene films could lead to flexible displays
HOUSTON – Graphene-based electrodes could revolutionize touch-screen displays, LED lighting and solar panels, bringing flexible, transparent electronics closer to reality. The thin films created in the lab of Rice University chemist James Tour combine a...
Dream Screens from Graphene
HOUSTON, Aug. 4, 2011 — Graphene-based electrodes developed by a team at Rice University could revolutionize touch-screen displays, solar panels and LED lighting, bringing flexible, transparent electronics closer to reality. Flexible, see-through video screens may be...
Laser Writes Storage into Graphite Sheets
HOUSTON, Aug. 4, 2011 — Using a CO2 laser, a Rice University team etched patterns of reduced graphite oxide (RGO) into thin sheets of graphite oxide (GO), effectively turning them into free-standing supercapacitors with the ability to store and release energy over...
Earthquake impact reverses NanoJapan plans
SENDAI, Japan, and HOUSTON – When it became clear that the effects of the March earthquake in Sendai were going to impede the undergraduate lab internship program known as NanoJapan, the program underwent a reversal: Instead of sending US students to Japan, students from...
Molecules 'Light Up' Alzheimer's Roots
HOUSTON, July 14, 2011 — A breakthrough in sensing at Rice University could make finding signs of Alzheimer's disease nearly as simple as switching on a light, and should help bring about better medications to treat the devastating disease. The lab of bioengineer...
Nanoantenna Enhances Plasmonic Sensing
BERKELEY, Calif., May 24, 2011 — An experimental demonstration of antenna-enhanced gas sensing at the single-particle level has been reported for the first time. By placing a palladium nanoparticle on the focusing tip of a gold nanoantenna, researchers with the US Department of...
Nanoantennas Hold Promise for IR Photovoltaics
HOUSTON, May 11, 2011 — A new device that can act as an optical antenna by collecting and focusing light, and as a photodiode by converting light into a current of electrons, has been developed by Rice University researchers. This nanoscale device, dubbed nanoantenna, has...
Imaging in the Ultrafast Lane
May 1, 2011 — For ultrafast imaging at wavelengths well below the visible, consider the work being done by a team led by professors Henry Kapteyn and Margaret Murnane. The married couple holds appointments in physics at the University of Colorado at Boulder and...
Team to Mimic Camouflage Skill of Cephalopods
WOODS HOLE, Mass., April 26, 2011 — Researchers at the Marine Biological Laboratory (MBL) are preparing to uncover the way in which cephalopods such as squids and octopi use light-sensing proteins in their skin to blend into their environment. What they find may lead to artificial...
Heat, Dissipation Measured at Molecular Level
HOUSTON, Dec. 29, 2010 — Researchers have figured out a way to determine the temperature of a molecule or flowing electrons by using Raman spectroscopy combined with an optical antenna. A new paper from the lab of Douglas Natelson, a Rice University professor of...
Metamaterials Research: ‘Project Squid Skin’
HOUSTON, Dec. 29, 2010 — Nanotechnologists, marine biologists and signal-processing experts from Rice University, the Marine Biological Laboratory in Woods Hole, Mass., and other US universities have won a $6 million grant from the Office of Naval Research to unlock the...
Doped Nanotubes Shine Brighter for Months
HOUSTON, Dec. 13, 2010 — Rice University researchers have discovered a simple way to make carbon nanotubes shine brighter. Bruce Weisman, a pioneer in nanotube spectroscopy and a researcher at Rice, found that adding tiny amounts of ozone to batches of single-walled...
Plasmonic antenna enhances spectroscopic studies
HOUSTON – The need for technologies that can detect molecules with high sensitivity is important in many fields. For applications ranging from industrial safety to homeland security, single-molecule sensitivity would be a highly valuable tool. Now an optical...
OSA Names 2011 VP
ROCHESTER, N.Y., Nov. 4, 2010 — The Optical Society of America (OSA) announced recently that its members have elected Donna T. Strickland as its 2011 vice president. In addition, three directors at large were also chosen at this year’s election, including Naomi J. Halas or...
Rebellion Photonics Wins Award for Chemical Imaging
HOUSTON, Nov. 1, 2010 — Rice University start-up, Rebellion Photonics, is this year’s grand prize recipient of the $50,000 Goradia Innovation Prize, an annual award given to a startup located in the Gulf Coast region with the most innovative technology, the best...
