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.
Optical Nanosensor Detects, Monitors Arsenic Level in Plants
SINGAPORE, Dec. 9, 2020 — A novel plant nanobionic optical sensor, capable of both detecting and, in real time, monitoring levels of arsenic in underground environments, exhibits changes in fluorescence intensity to indicate the presence and quantity of the metal. Scientists...
Uses Broaden for Wonky Nanotubes
USURBIL, Spain, Nov. 1, 2013 — A light emitter based on boron nitride nanotubes emits light across much of the electromagnetic spectrum, and can easily be incorporated into current microelectronics technology and used to develop high-efficiency optoelectronic devices, new...
Laser Imaging System Screens Nanotubes
WEST LAFAYETTE, Ind., Nov. 22, 2010 — Researchers have demonstrated a new imaging tool for rapidly screening structures called single-wall carbon nanotubes, possibly hastening their use in creating a faster and more energy-efficient class of computers and electronics. The semiconducting...
Solid-state Sensor Combines Optics, Electronics
PITTSBURGH, Nov. 17, 2010 — University of Pittsburgh researchers have created a nanoscale light sensor that can be combined with near-atomic-size electronic circuitry to produce hybrid optic and electronic devices with new functionality. The team, which also involved...

Cambridge NanoTech Partners with Stanford
CAMBRIDGE, Mass., June 21, 2010 — Atomic layer deposition (ALD) science and equipment provider, Cambridge NanoTech, announced Tuesday its partnership with Stanford University’s Center for Integrated Systems (CIS), a partnership between academia and industry that supports...
Gecko Grip Given to Any Surface
HOUSTON, Jan. 27, 2010 – A graduate student at Rice University has devised a way to transfer the gravity-defying grip of a gecko – so strong it can stick to even glass – from any surface to anoth...
Lasers Spin Nanotube Yarn
NEWPORT NEWS, Va., Dec. 3, 2009 – Lasers now have been used to create the first practical macroscopic yarns from boron nitride fibers, opening the door for an array of applications from solar cells to stronger body armor. Researchers created a technique to synthesize high-quality...
Green Bacteria Harvests Light
UNIVERSITY PARK, Pa., May 5, 2009 – The structure of chlorophyll molecules in green bacteria that are responsible for harvesting light energy were determined by an international team of scientists. The discovery could one day be used to build artificial photosynthetic systems, like...
Clear Transistors Printed
LOS ANGELES, Dec. 17, 2008 -- Using a low-temperature process, engineers have printed a lattice of more than 20,000 n-type and p-type nanotube transistors capable of high-performance electronics on a clear, colorless, 5-in. disk that's as flexible as a playing card. The...
Nanotubes the New Asbestos?
WASHINGTON, D.C., May 21, 2008 – Nanotubes may be tiny, but they are super strong carbon fibers that play an important role in the advancement of nanotechnology. However, researchers are now saying that the long, thin multi-walled carbon nanotubes that look like asbestos fiber,...
Straight CNTs Made in Volume
DURHAM, N.C., April 25, 2008 -- Chemists have found a way to grow long, straight carbon nanotubes (CNTs) only a few atoms thick in very large numbers, removing a major roadblock in the pursuit of nanoscale electronics. These single-walled CNTs also follow parallel paths as...
Sensor Tracks Insulin Level
NASHVILLE, Tenn., April 16, 2008 -- A sensor built from multiwalled carbon nanotubes can rapidly and continuously measure tiny amounts of insulin in a microfluidic device. Used in conjunction with a new procedure for treating Type 1 diabetes through liver cell transplant, the device...
CNTs Nontoxic in Mice
STANFORD, Calif., Jan. 31, 2008 -- Carbon nanotubes (CNTs) tracked inside mice for months were found to be nontoxic, research that may give a boost to using the tiny cylinders in biomedical applications. CNT cylinders are so small that it takes 50,000 lying side by side to equal...
Model Evaluates Biosensors
WEST LAFAYETTE, Ind., Jan. 7, 2008 -- A new modeling technique explains for the first time why a single nanotube performs better than sensors containing several nanotubes or flat planar sensors and refutes a popular explanation for why smaller sensors work better than larger...
Buckyball Formation Observed
ALBUQUERQUE, N.M., Nov. 28, 2007 -- A Sandia National Laboratories researcher looking for flaws in nanotube durability was unexpectedly able to experimentally confirm a hypothesis about how Buckyballs form. “We have now the first direct, in situ, experimental proof of the...
Nanotubes Mass-Produced
HOUSTON, Sept. 7, 2007 -- A new fabrication technique called nanopantography can create billions of carbon nanotubes in hours and could help popularize a technology that renders LCDs obsolete. Professors Vincent Donnelly, Demetre Economou and Paul Ruchhoeft, all of the...
Solar, Nano Big at SPIE Show
SAN DIEGO, Aug. 16, 2007 -- Solar energy and nanotechnology will be the main topics of numerous plenary sessions during the Optics + Photonics conference, Aug. 26-30 at the San Diego Convention Center. Sponsored by SPIE, Optics + Photonics includes more than 3100 technical...
