'Nano traps' to lock up and neutralize viruses
To date, there are no effective antidotes against most virus infections. An interdisciplinary research team at the Technical University of Munich (TUM) has now developed a new approach: they engulf and neutralize viruses with nano-capsules tailored from genetic material using the DNA origami method. The strategy has already been tested against hepatitis and adeno-associated viruses in cell…

Microrobots could re-shape drug delivery
Scientists have developed minute flexible robots that could help revolutionise drug delivery in the future. These ‘microrobots’ are so small that they could be ingested, or inserted into human veins to deliver drug therapies directly to diseased body areas.

Revealing the fluctuations of flexible DNA in 3-D
An international team working at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has captured the first high-resolution 3-D images from individual double-helix DNA segments attached at either end to gold nanoparticles. The images detail the flexible structure of the DNA segments, which appear as nanoscale jump ropes.
