An international team of scientists has shed new light on a fundamental area of physics which could have important implications for future electronic devices and the transfer of information at the quantum level.
Each year, twice as many people die in Europe from hospital acquired infections than from road accidents. These infectious diseases have developed antibiotic resistance and spread despite the best efforts of staff, mainly through textiles like bed linen. But the technology developed by a European research project helps fight back against the so-called superbugs, by using a revolutionary nanotechnology to treat bed linen and other textiles.
Pioneering biophotonics technology developed at Northwestern University is the first screening method to detect the early presence of ovarian cancer in humans by examining cells easily brushed from the neighboring cervix or uterus, not the ovaries themselves.
The latest advances in microtechnologies for smart sensors, energy harvesting, smart power, reconfigurable multimedia, wireless communication, and biomedical applications will be presented next month in Grenoble at SPIE Microtechnologies. The event attracts researchers and developers for an interdisciplinary exchange of technology advances and discussion of future applications.
A Harvard-led team of researchers has created a new type of nanoscale device that converts an optical signal into waves that travel along a metal surface. Significantly, the device can recognize specific kinds of polarized light and accordingly send the signal in one direction or another.
Good news for the computer industry: a team of researchers has managed to make germanium suitable for lasers. This could enable microprocessor components to communicate using light in future, which will make the computers of the future faster and more efficient.
A dye-based imaging technique known as two-photon microscopy can produce pictures of active neural structures in much finer detail than functional magnetic resonance imaging, or fMRI, but it requires powerful and expensive lasers. Now, a research team at the University of Pennsylvania has developed a new kind of dye that could reduce the cost of the technique by several orders of magnitude.
In a new study performed at the Center for Nanoscale Materials at the U.S. Department of Energy's (DOE) Argonne National Laboratory, researchers have for the first time seen the self-assembly of nanoparticle chains in situ, that is, in place as it occurs in real-time.
Scientists fabricated an electrochemical DNA biosensor by studying interactions between antimicrobial drug and double stranded DNA on the surface of glassy carbon electrode modified with multi-walled carbon nanotube.
Researchers at the University of Exeter have developed a new photoelectric device that is both flexible and transparent. The device converts light into electrical signals by exploiting the unique properties of the recently discovered materials graphene and graphExeter. GraphExeter is the best known room temperature transparent conductor and graphene is the thinnest conductive material.
In search of a definitive conclusion on the potential risks, the EU funded PROSUITE project has been set up to analyse the environmental impact of nanosilver released from sports T-shirts during their entire life cycle, from raw material extraction to end-of-life disposal.
Researchers have developed and tested a solar-powered nano filter that is able to remove harmful carcinogens and antibiotics from water sources - lakes and rivers - at a significantly higher rate than the currently used filtering technology made of activated carbon.
