Rice University Rice, MD Anderson scientists refine technique for attacking hard-to-reach tumors Short, customized carbon nanotubes have the potential to deliver drugs to pancreatic cancer cells and destroy them from within, according to researchers at Rice University and the University of Texas MD Anderson Cancer Center. Pristine nanotubes produced through a new process developed at Rice can be modified to carry drugs to tumors through gaps in blood-vessel walls that larger...

A carbon nanotube sponge capable of soaking up water contaminants, such as fertilizers, pesticides and pharmaceuticals, more than three times more efficiently than previous efforts has been presented in a new study published today. The carbon nanotube (CNT) sponges, uniquely doped with sulphur, also demonstrated a high capacity to absorb oil, potentially opening up the possibility of using the material in industrial accidents and oil spill clean-ups. The results have been published...

Researchers Develop Technique For Imaging Individual Carbon Nanotubes

Lawrence Berkeley National Laboratory Despite their almost incomprehensibly small size – a diameter about one ten-thousandth the thickness of a human hair – single-walled carbon nanotubes come in a plethora of different “species,” each with its own structure and unique combination of electronic and optical properties. Characterizing the structure and properties of an individual carbon nanotube has involved a lot of guesswork – until now. Researchers with the U.S. Department of...

Nitric oxide (NO) is one of the most important signaling molecules in living cells, carrying messages within the brain and coordinating immune system functions. In many cancerous cells, levels are perturbed, but very little is known about how NO behaves in both healthy and cancerous cells. "Nitric oxide has contradictory roles in cancer progression, and we need new tools in order to better understand it," says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT....

New Device To Detect Disease With Drop Of Blood Being Developed
2013-06-24 09:51:00

New Jersey Institute of Technology An NJIT research professor known for his cutting-edge work with carbon nanotubes is overseeing the manufacture of a prototype lab-on-a-chip that would someday enable a physician to detect disease or virus from just one drop of liquid, including blood. "Scalable nano-bioprobes with sub-cellular resolution for cell detection," Biosensors and Bioelectronics, (Elsevier, Vol. 45), which will publish on July 15, 2013 but is available now online, describes how...

Carbon Nanotube Harpoon Used to Catch Individual Brain-cell Signals
2013-06-20 11:33:48

Duke University Neuroscientists may soon be modern-day harpooners, snaring individual brain-cell signals instead of whales with tiny spears made of carbon nanotubes. The new brain cell spear is a millimeter long, only a few nanometers wide and harnesses the superior electromechanical properties of carbon nanotubes to capture electrical signals from individual neurons. "To our knowledge, this is the first time scientists have used carbon nanotubes to record signals from individual...

An ultimate goal in the field of carbon nanotube research is to synthesise single-walled carbon nanotubes (SWNTs) with controlled chiralities. Twenty years after the discovery of SWNTs, scientists from Aalto University in Finland, A.M. Prokhorov General Physics Institute RAS in Russia and the Center for Electron Nanoscopy of Technical University of Denmark (DTU) have managed to control chirality in carbon nanotubes during their chemical vapor deposition synthesis. Carbon nanotube structure...

A nanomaterial engineered by researchers at Duke can help regulate chloride levels in nerve cells that contribute to chronic pain, epilepsy, and traumatic brain injury. The findings, published online Dec. 10, 2012, in the journal Small, were demonstrated in individual nerve cells as well as in the brains of mice and rats, and may have future applications in intracranial or spinal devices to help treat neural injuries. Carbon nanotubes are a nanomaterial with unique features, including...
