Nanotube coating helps shrink mass spectrometers

(Purdue University 25 March 2014) Nanotechnology is advancing tools that perform on-the-spot chemical analysis for a range of applications including medical testing, explosives detection and food safety.When paper used to collect a sample was coated with carbon nanotubes, the voltage required was 1,000 times reduced, the signal was sharpened and the equipment was able to capture far more delicate molecules.The research is detailed in a designated ‘very important paper’ by the journal Angewandte Chemie.

Catching the early spread of breast cancer

(American Chemical Society 19 March 2014) When cancer spreads, it becomes even more deadly. It moves with stealth and can go undetected for months or years. But a new technology that uses ‘nano-flares’ has the potential to catch these tumor cells early. Today, at the 247th National Meeting & Exposition of the American Chemical Society, scientists presented the latest advances in nano-flare technology as it applies to the detection of metastatic breast cancer cells

Nanorods detect DNA traces with higher sensitivity

BioOptics World Lee Dubay 28 October 2013

An international team of researchers at the University of Michigan (Ann Arbor, MI) and Jiangnan University in China has demonstrated that light-activated nanorods can detect tiny amounts of DNA with 50x more sensitivity than current methods. The work could help with diagnosing patients, solving crimes, and identifying the origins of biological contaminants, such as a pathogen in a water supply.

Public wants labels for food nanotech — and they’re willing to pay for it

(North Carolina State University 28 October 2013) New research finds that people in the United States want labels on food products that use nanotechnology — whether the nanotechnology is in the food or is used in food packaging. The research also shows that many people are willing to pay more for the labeling.

UCLA researchers’ smartphone ‘microscope’ can detect a single virus, nanoparticles

(University of California – Los Angeles 16 September 2013) Your smartphone now can see what the naked eye cannot: A single virus and bits of material less than one-thousandth of the width of a human hair. Aydogan Ozcan, a UCLA professor of engineering, has created a portable smartphone attachment to enable sophisticated field testing of fluid and solid samples for detection of viruses and bacteria without need for bulky and expensive microscopes and lab equipment. The device weighs less than half a pound.
