MIT mathematicians have derived a formula for determining the maximum amount of heat exchanged between two objects separated by distances shorter than the width of a single hair. For any two objects situated mere nanometers apart, the formula can be used to calculate the most heat one body may transmit to another, based on two parameters: what the objects are made of, and how far apart they are.
Vivid holographic images and text can now be produced by means of an ordinary inkjet printer. This new method, developed by a team of scientists from ITMO University in Saint Petersburg, is expected to significantly reduce the cost and time needed to create the so-called rainbow holograms, commonly used for security purposes -- to protect valuable items, such as credit cards and paper currency, from piracy and falsification.
Researchers have developed a process to remove contaminants from oil sands wastewater using only sunlight and nanoparticles that is more effective and inexpensive than conventional treatment methods.
MIT researchers have developed a biomedical imaging system that could ultimately replace a $100,000 piece of a lab equipment with components that cost just hundreds of dollars. The system uses a technique called fluorescence lifetime imaging, which has applications in DNA sequencing and cancer diagnosis, among other things. So the new work could have implications for both biological research and clinical practice.
Miniaturization is the magic word when it comes to nanomagnetic devices intended for use in new types of electronic components. Scientists from the Helmholtz-Zentrum Dresden-Rossendorf have proposed the use of ion beams for their fabrication. An ultra-fine beam consisting of around 10 neon ions suffices to bring several hundred atoms of an iron-aluminum alloy into disarray and thereby generate a nanomagnet embedded directly in the material.
Engineers at the University of California, San Diego developed a new technology that uses an oscillating electric field to easily and quickly isolate drug-delivery nanoparticles from blood. The technology could serve as a general tool to separate and recover nanoparticles from other complex fluids for medical, environmental, and industrial applications.
Nanomedicine, a leading MEDLINE-indexed journal, has published a special focus issue highlighting the interdisciplinary nature of this emerging field, which explores the medical application of nanotechnology to monitor, repair, and control human biological systems at the molecular level. Nanomedicine is published by Future Science Group.
Berkeley Lab researchers have developed a new family of nanocarriers, called '3HM,' that meets all the size and stability requirements for effectively delivering therapeutic drugs to the brain for the treatment of a deadly form of cancer known as glioblastoma multiforme.
The Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw has just unveiled two new catalysts developed in close cooperation with the Jagiellonian University in Cracow and the Jan Kochanowski University in Kielce. The catalysts have been designed with the effective treatment of tap water in mind, eliminating harmful chlorine compounds.
A collaboration between investigators at Massachusetts General Hospital and Brigham and Women's Hospital has led to a new approach that uses an FDA-approved, magnetic nanoparticle and magnetic resonance imaging to identify tumors most likely to respond to drugs delivered via nanoparticles. The team's preclinical results are published in Science Translational Medicine Nov. 18.
