Carbon nanotubes have already found applications in engineering but so far any biological application has been hampered by their poor interaction with biological systems. The Surrey team has overcome this problem by wrapping DNA and RNA around carbon nanotubes making them biocompatible.
The aim of the project is to attach additional molecules to the RNA-wrapped carbon nanotubes to target them towards cancer cells. In combination with laser treatment the carbon nanotubes may then be used to kill the cancer cells. Although there is still a long way to go before any new drugs based on this technology are developed, the scientists hope that their work will eventually lead to more effective treatments for cancer.
The multidisciplinary project involves biologists, engineers and physicists from the University of Dresden in Germany, the University of Toulouse, France, the University of Linz, Austria, the University of Twente, The Netherlands and the University of Surrey. Further information is available from the CARBIO website http://www.carbio.eu/ . The work at Surrey is headed by Professor Johnjoe McFadden, Professor Ravi Silva, and Dr Helen Coley from the disciplines of Electronic Engineering, Biology and Medicine, respectively.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
