Molecular 'machine' is a tail-biter which functions as a nanoswitch

The ouroboros (ancient Greek for 'tail devourer') is a motif found in many cultures: a snake biting its own tail, it symbolizes eternity and cycles. Researchers have now constructed a molecular tail devourer, and have named this new class of compound 'ouroborand'. Their tail-biter is a molecular 'machine', which functions as a nanocontainer with a built-in switch that regulates access to the cavity.

Magnetic fields drive drug-loaded nanoparticles to reduce blood vessel blockages

Scientists and engineers have used uniform magnetic fields to drive iron-bearing nanoparticles to metal stents in injured blood vessels, where the particles deliver a drug payload that successfully prevents blockages in those vessels. In this animal study, the novel technique achieved better results at a lower dose than conventional non-magnetic stent therapy.

Flexible plastic chips monitor body functions

A small blood lab that fits into the pocket of a jacket can quickly analyze the risk of blood clots in legs prior to a long distance flight; a sensor wristband for measuring electric smog can warn pacemaker patients of life-threatening exposure: 'Smart plastics' can turn such tools into reality.

Novel memristor chips for tomorrow's energy-efficient computers

A working group headed by Professor Rainer Waser from Forschungszentrum Juelich and RWTH Aachen University has developed a novel switching concept and the related technology for so-called memristor chips. With their research findings, the scientists are preparing for a paradigm shift in the architecture of computer chips.
