Newly fabricated devices are a step toward quantum computing Moving a step closer toward quantum computing, a research team in the Netherlands recently fabricated a photodetector based on a single nanowire, in which the active element is a single quantum dot with a volume of a mere 7,000 cubic nanometers. The device is described in the American Institute of Physics' journal Applied Physics Letters. Photodetectors based on single quantum dots are expected to find uses in optoelectrical...

One of the holy grails of nanotechnology in medicine is to control individual structures and processes inside a cell. Nanoparticles are well suited for this purpose because of their small size; they can also be engineered for specific intracellular tasks. When nanoparticles are excited by radio-frequency (RF) electromagnetic fields, interesting effects may occur. For example, the cell nucleus could get damaged inducing cell death; DNA might melt; or protein aggregates might get dispersed....

Researchers at the University at Buffalo have developed a novel technology using quantum dots that is expected to have major implications for research and treatment of tuberculosis, as well as other inflammatory lung diseases. A paper appearing online in Nanomedicine: Nanotechnology, Biology and Medicine as an article-in-press describes specific delivery of a chemotherapeutic drug to specific cells in the lung, particularly the alveolar white cell, without causing acute inflammation. Quantum...

Getting an inside look at the center of a cell can be as easy as a needle prick, thanks to University of Illinois researchers who have developed a tiny needle to deliver a shot right to a cell's nucleus. Understanding the processes inside the nucleus of a cell, which houses DNA and is the site for transcribing genes, could lead to greater comprehension of genetics and the factors that regulate expression. Scientists have used proteins or dyes to track activity in the nucleus, but those can be...

An international research group led by scientists from the University of Bristol has developed a new approach to quantum computing that could soon be used to perform complex calculations that cannot be done by today's computers. Scientists from Bristol's Centre for Quantum Photonics have developed a silicon chip that could be used to perform complex calculations and simulations using quantum particles in the near future. The researchers believe that their device represents a new route to a...

The PhD thesis by Carlos Echeverría Arrondo, Doctor in Physics from the Public University of Navarre and entitled "On doped semiconductor quantum dots and magnetic nanowires", studied the behaviour and properties of nanometric-scale semiconductor crystals. The interest aroused by nanoscience and nanotechnology spurred Dr Echeverría to study the behaviour of semiconductor crystals when their size is reduced to less than one hundred nanometres (a nanometre is...
