Chemistry World February 13, 2011 James Urquhart	Guiding electrons through graphene US researchers have created a graphene-based device that guides electrons through the material in the same way an optical fiber guides light, using electrical gates.
Chemistry World February 10, 2011 Laura Howes	Space ice goes against the grain Space ice made from a mixture of methanol and water expands under pressure, and shrinks when heated - the opposite behaviour to most solids.
Chemistry World February 10, 2011 James Urquhart	Molecular motor controls chirality A single molecule catalytic system that uses a light driven molecular motor to dynamically control the molecule's chiral states has been developed by scientists in the Netherlands.
Chemistry World February 10, 2011 Erica Wise	Raman imaging gives new hope for cancer diagnosis Surface enhanced Raman scattering works by detecting spectroscopic signals of molecules such as cancer antibodies that are in close proximity to metals injected into tissue such as gold or silver nanoparticles.
Chemistry World February 8, 2011 Laura Howes	Neurotoxin detection using brain nanotubes Chan Beum Park's team in Korea, has used these nanotubes to give an optical signal in the presence of phosphate based neurotoxin paraoxon
Chemistry World February 4, 2011	MOF magnets deliver drugs German scientists have encapsulated nanomagnets inside metal organic frameworks. The MOF magnets can be filled with a drug, which is released when a magnetic field is applied.
Chemistry World February 4, 2011 Harriet Brewerton	Transplant tracking Magnetic nanoparticles could be used to track neural stem cells after a transplant in order to monitor how the cells heal spinal injuries, say UK scientists.
Chemistry World February 3, 2011 Hayley Birch	Nanoparticle studies guide coating design A new study provides guidance for designing nanoparticle coatings based on the particles' size and the environment they are to be used in. The research could help scientists create more effective nanoparticle drug carriers.
Chemistry World February 3, 2011 Mike Brown	Exfoliating layered materials Layered materials can be separated into individual sheets with enhanced electronic properties using a new quick and simple method, says an international team of researchers.
Chemistry World January 30, 2011 Mike Brown	Electrons charge down DNA molecular wire US researchers have shown for the first time that a 34nm long DNA strand can be used as a molecular wire to conduct electricity.
