Plasma Synthesis of Metal Sulfide Nanocrystals [On Location]

. by Martin Bergstedt

Metal sulfide nanocrystals have typically been synthesized in hot solvent-solution phase systems that bring with them a host of quality and productivity issues. Current work at the University of Minnesota seeks to avoid these problems by utilizing a non-thermal plasma reactor and deposition system.

This year's meeting, Bionanoscience and Bioengineering for Translational Medicine, will foster greater knowledge exchange and collaboration in the areas of bioengineering and nanotechnology – two interdisciplinary fields that cut across and integrate various areas in science, engineering, and medicine to create breakthroughs in biomedical research.

Conductive Nanotube Cables Could Advance Renewable Energy and More

. by Douglas B. Clark

Researchers at Rice University have announced a nanotechnology success that could play a significant role in making renewable energy more practical and could contribute to many electrical applications where weight is a factor. The breakthrough: researchers have created carbon nanotubes that are approaching electrical conductivities seen in metal wires, a goal that has been pursued since the 1980s.

Thomas Abraham on Nanotechnology at 2011 AIChE Northeast Regional Conference at the Chem Show

. by John Vasko

Tom Abraham of Innovative Research and Products (IRAP) has produced the Nanotechnology Workshops and Conference at the Chem Show every other year since 2005. This year will be the first time this conference will be produced in conjunction with AIChE. Conference Organizer Lauren Deitch had a chance to sit down and chat with Dr. Abraham at AIChE's offices in New York. You can watch the interview in the video panel to the right.

Tattoos as Diagnostic Devices

. by Douglas B. Clark

There's not much sexy—let alone unobtrusive—about many of today's medical monitoring devices, given the many wires and electrodes that are often needed to collect data from a patient. But that may be about to change. A professor of materials science has created an "electronic tattoo" that can monitor various body functions

New Nanotechnology Helps Heal Heart Tissue

. by ChEnected Guest

Researchers at Brown University have used carbon nanotubes to create a patch that can regenerate heart tissue in the lab, according to a report in Technology Review. The patch is formed of chains of carbon atoms that fold onto themselves to create a tube that is capable of conducting electricity and mimics the surface of natural tissue.

Chemical Engineers Design Nanoparticles to Target Cancer Tumors

. by Douglas B. Clark

Chemical engineers at MIT have designed a nanoparticle that could one day be used to target cancerous tumors, reports MIT News. The particle, which could be used to deliver drugs to tumors, takes advantage of the fact that tumors generally exhibit higher acidity that healthy tissue. Like other drug-delivering nanoparticles, the researchers' creation is covered in a polymer that keeps it from degrading in the bloodstream. These particles, however, drop their protective polymer cloak once exposed to the higher acidity of a tumor. Underneath the protective coating is another layer that can penetrate the tumor. The particles are described in detail in the journal ACS Nano.

Antibiotic-Resistant Bacteria Fought with Nanoparticles

. by Douglas B. Clark

IBM researchers are developing nanoparticles that kill bacteria by poking holes in them. The hope is that bacteria will be less successful at developing a resistance to these types of drug, leaving doctors with a powerful tool in the fight against antibiotic-resistant microbes.

Allergy to Cheap Jewelry? Nanoparticles May Make It a Thing of the Past

. by Sandro Matosevic

Nickel-induced dermatitis is more common than it sounds. In fact, about fifteen percent of the US population is allergic to the nickel found in many everyday objects, such as jewelry, watches, metal household items, and coins. The allergy itself is due to nickel salts formed by contact-induced perspiration, and, of course, isn’t helped by the wide availability of cheap disposable jewelry.

Nanoparticle versus Cancer

. by Douglas B. Clark

Whenever cancer is discussed, a familiar phrase is often heard: the earlier it's caught, the better the chances of survival. Early detection is the next best thing to avoiding cancer altogether, and now researchers are hoping to have discovered a safe, new method of detection that relies on a newcomer in the fight for early detection: the nanoparticle. More specifically, MIT's Tech Review reported last week that researchers are beginning early-stage clinical trials on infrared-emiting nanoparticles that they hope will prove effective in detecting early-stage melanoma.
