Early tests find nanoshell therapy effective against brain cancer

Rice University bioengineers and physician-scientists at Baylor College of Medicine and Texas Children's Hospital have successfully destroyed tumors of human brain cancer cells in the first animal tests of a minimally invasive treatment that zaps glioma tumors with heat. The tests involved nanoshells, light-activated nanoparticles that are designed to destroy tumors with heat and avoid the unwanted side effects of drug and radiation therapies.

Handheld nanoLAB suitable for in-home use detects disease proteins in minutes

Driven by scientific progress and economic stimulus, medical diagnostics will move to a stage in which straightforward medical diagnoses are independent of physician visits and large centralized laboratories. The future of basic diagnostic medicine will lie in the hands of private individuals. Researchers have taken significant strides towards achieving this goal by developing an autoassembly assay for disease biomarker detection which obviates the need for washing steps and is run on a handheld sensing platform.

Enabling nanoparticles to penetrate deeply in tumors

A large team of researchers from the Massachusetts Institute of Technology, Massachusetts General Hospital, and Harvard Medical School have developed multilayered, or multistage, nanoparticles that partially dissolve once they accumulate around tumors, leaving behind a payload of nanoparticles a mere one-tenth the size of the original delivery vehicle.

Toward computers that fit on a pen tip: New technologies usher in the millimeter-scale computing era

A prototype implantable eye pressure monitor for glaucoma patients is believed to contain the first complete millimeter-scale computing system. And a compact radio that needs no tuning to find the right frequency could be a key enabler to organizing millimeter-scale systems into wireless sensor networks. These networks could one day track pollution, monitor structural integrity, perform surveillance, or make virtually any object smart and trackable.

Research breakthrough for photons in the microwave frequency range

Photons in the microwave frequency range are important in quantum research - for quantum information processors, for example. Now, for the first time, researchers have achieved the controlled production of single photons in the microwave region and successfully detected them with highly sensitive measuring instruments - although they are 100,000 times weaker than the photons emitted by an electric light bulb.

World Gold Council launches initiative to accelerate the development of emerging technologies utilising gold

The World Gold Council today announced that it is to play a pivotal role in the transition of new gold-based innovations from 'lab' to 'market'. There has been an explosion of interest in the use of gold in science and technology, mainly driven by the emergence of nanotechnology, yet breakthroughs in research are slow to achieve commercial success due to lack of further targeted investment and support.
