Titanium Oxide Challenges Gold Standard Photoporation Method
TOYOHASHI, Japan, Jan. 27, 2021 — Researchers in the mechanical engineering department at Toyohashi University of Technology (TUT) have developed a low-cost photoporation method using titanium-oxide nanotubes. Photoporation is a technique that relies on focused light to perforate the cell membrane, creating an opening through which substances may enter the membrane. Because photoporation has in application traditionally used gold nanoparticles, which absorb pulsed light, the technique has often been expensive to practice.
Light-Emitting Nanosensors Track Chemical Signals in Plants
CAMBRIDGE, Mass., April 30, 2020 — An international research team led by Tedrick Lew and Michael Strano at the Massachusetts Institute of Technology have created a new device for observing variations in waves of hydrogen peroxide as they pass through the tissues of different species...
Color Superlensing Could Break Through Diffraction Barrier
KAZAN, Russia, Jan. 23, 2020 — Researcher Sergey Kharinstev and his team at Kazan Federal University recently published a paper in Optics Letters where they detail the design of a new type of metalens capable of imaging beyond the optical diffraction limit.
New Device Makes Better Use of Sunlight
CAMBRIDGE, Mass., Jan. 21, 2014 — A team at MIT has discovered a way to harvest solar energy more efficiently and potentially on demand.
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...
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,...
Nanotubes improve hologram projection
CAMBRIDGE, England – Holograms can be generated by harnessing the conductive and light-scattering qualities of carbon nanotubes, a development that could lead to crisper projections with a larger field of view. Many scientists believe that carbon nanotubes will be at...

CAMBRIDGE, UK – Holograms can be generated by harnessing the conductive and light-scattering qualities of carbon nanotubes, a development that could lead to crisper projections with a larger field of view. Many scientists believe that carbon nanotubes will be at...
Nanotubes Project Holograms
CAMBRIDGE, England, Sept. 25, 2012 — Holograms can be generated by harnessing the conductive and light-scattering qualities of carbon nanotubes, a development that could lead to crisper projections with a larger field of view.
Red-light-emitting carbon nanotubes could brighten OLEDs
WARSAW, Poland – Carbon nanotubes with light-emitting chemicals attached glow with red light when exposed to ultraviolet wavelengths. Inducing carbon nanotubes to emit light is difficult, as they are excellent electrical conductors and capture energy from...
Nanotubes Store Solar Energy Indefinitely
CAMBRIDGE, Mass., July 15, 2011 — Carbon nanotubes can be used to store solar energy and can be recharged when exposed to the sun. Storing the sun's heat in chemical form — rather than converting it to electricity or storing the heat itself in a heavily insulated...
Acoustical Waves Tapped for Metamaterials
LOS ALAMOS, N.M., April 7, 2011 — A very simple benchtop technique that uses the force of acoustical waves to create a variety of 3-D structures will benefit the rapidly expanding field of metamaterials and its myriad applications. Metamaterials are artificial materials...
Carbon nanotubes as optical antennae
ITHACA, N.Y. – Researchers at Cornell University have found that carbon nanotubes’ light transmission behaves as a scaled-down version of radio-frequency antennae found in walkie-talkies, except that the interaction is with light instead of radio waves. The...
Procedure Produces Sharper AFM Probes
JENA, Germany, Nov. 2, 2010 — Scientists from Friedrich-Schiller-University Jena were successful in improving a fabrication process for atomic force microscopy (AFM) probe tips. Stephanie Hoeppener is working with an atomic force microscope for which a Jena research team...
NanoIntegris Signs Contract with Kanto
CHICAGO, Oct. 27, 2010 — NanoIntegris Inc., a supplier of 99 percent pure semiconducting and metallic carbon nanotubes, announced its entrance into a distribution contract with Kanto Chemical Co. Inc. of Portland, Ore., a supplier of electronic materials to the...
“Greening” Your Flat-Screen TV
TEL AVIV, Israel, Sept. 7, 2010 — Researchers at Tel Aviv University developed an environmentally friendly organic LED light source for home electronics, medicine and clean energy. The new light source applies a discovery in nanotechnology, based on self-assembled peptide nanotubes,...
Nanotubes Cover Ultradark Detector
GAITHERSBURG, Md., Aug. 19, 2010 — Harnessing darkness for practical use, researchers at NIST have developed a laser power detector coated with the world’s darkest material — a forest of carbon nanotubes that reflects almost no light across the visible and part of the...
Nanotubes Create Atomic ‘Black Hole’
CAMBRIDGE, Mass., April 7, 2010 — Carbon nanotubes, long touted for applications in materials and electronics, may also be the stuff of atomic-scale black holes. Physicists at Harvard University have found that a high-voltage nanotube can cause cold atoms to spiral inward under...
ICALEO 2009 Leans Green
ORLANDO, Fla., Oct. 14, 2009 – Up-to-the-minute developments in carbon nanotubes and photovoltaics – technologies at the forefront of the growing “green” movement in energy and manufacturing – and the critical role lasers play in this global revolution will be presented during...
Carbon Design Receives Grant
Aug 12, 2009 — Carbon Design Innovations Inc., a carbon nanotube device manufacturer located in Burlingame, Calif., has received a $390,000 grant from the National Institutes of Health (NIH) Small Business Innovation Research (SBIR) Program. The grant will fund...
Heat Tracked in Nanotubes
YORKTOWN HEIGHTS, NY, March 2, 2009 – In a landmark study in the field of nanoelectronics, IBM Research scientists have announced the development and demonstration of techniques that measure the distribution of energy and heat in powered carbon nanotube devices. By employing these...
Optical Interferometry Measures the Deflection of Carbon-Based Nanosensors
Jun 1, 2008 — The reduction in size of modern electromechanical systems — from micro (MEMS) to nano (NEMS) — brings with it decreasing dimensions to be tested and characterized. Thus, the sensitivity requirements of the testing device and methodology are...
