The mystery behind a detection method that can sense the presence of individual molecules - useful for researchers analyzing artwork and anthrax alike - has been unraveled by scientists with the Lawrence Berkeley National Laboratory.
UCLA researchers have redefined the concept of a microscope by removing the lens to create a system that is small enough to fit in the palm of a hand but powerful enough to create three-dimensional tomographic images of miniscule samples.
The scientist who developed the world's most sensitive spectrometer for identifying atoms on a material's surface came to Lehigh recently to give a talk at the only U.S. lab that is equipped with his cutting-edge instrument.
Los Alamos National Laboratory scientists have developed a way to avoid the use of expensive platinum in hydrogen fuel cells, the environmentally friendly devices that might replace current power sources in everything from personal data devices to automobiles.
A collaboration between the Whitesides Group at Harvard University and CSM Instruments has culminated in an important advance in lithography of different materials at the nanoscale. The motivation for this development was the ability to produce unique lithographical patterns of different shapes and sizes for use in research applications (e.g. lab-on-a-chip) where conventional techniques such as electron-beam lithography (EBL) and photolithography cannot be used.
The tools of nanobiotechnology have wide-ranging commercial impact on fields that include pharma, medtech, textiles, agriculture, consumer products and many more. There are many hotbeds of nanobiotech innovation, and North Carolina has emerged as a leader in nanobiotech research, development and commercialization.
A University of Arkansas physicist has received the largest award granted to an individual researcher from the Army Research Laboratory to search for a novel class of nanomaterials with rationally designed properties.
An alliance of top researchers at the University of California, Berkeley, has formed the UC Berkeley Synthetic Biology Institute (SBI), advancing efforts to engineer cells and biological systems in ways that promise to transform technology in health and medicine, energy, the environment, new materials, and a host of other critical arenas.
Nanotechnology researchers have known for years that RNA, the cousin of DNA, is a promising tool for nanotherapy, in which therapeutic agents can be delivered inside the body via nanoparticles. But the difficulties of producing long-lasting, therapeutic RNA that remains stable and non-toxic while entering targeted cells have posed challenges for their progress. Now, researchers detail successful methods of producing large RNA nanoparticles and testing their safety in the delivery of therapeutics to targeted cells.
The Food Standards Agency (FSA) in the UK has published a report of consumers' views on the use of nanotechnology in food and food packaging. The focus group research, which asked participants about their views on nanotechnology in late 2010 and early 2011, was carried out as part of the FSA's programme of work on nanotechnology.
Researchers at National Nanotechnology Center (NANOTEC) in Bangkok have studied the application of niosomes for encapsulation of nisin and EDTA. Nisin (Food Additive, E234) are used as antimicrobial substance in food and pharmaceutical applications.
The development of new methods that use engineered nanomaterials to transport drugs and release them directly into cells holds great potential in this area. And while several such drug-delivery systems have won approval for clinical use, they have been hampered by size limitations and ineffectiveness in accurately targeting tissues. Now, researchers at UCLA have developed a new and potentially far more effective means of targeted drug delivery using nanotechnology.
