cover: shining a light on the molecular fingerprint

Made of a single molecule, the tiny artificial sensor might be able to “smell out” disease within living cells

heat transfer in graphene

A nanothermometer is thousands of times better at detecting heat transfer at the atomic level

A bowtie-shaped nanoparticle

Bowtie-shaped nanostructures may advance the development of quantum devices

The future of solar energy might lie in light-absorbing paints

Tough Enough
Adding nanotubes to composite materials should greatly enhance their properties
 A certain sequence of letters, EBU, creates chemical conditions in which an iron atom disconnects itself from an organic molecule (on the right), activating it and causing it to emit green fluorescent light. The sequence EUB leads to the emission of blue light. Other sequences of letters do not cause light emission
Organic molecules could form the basis of ultra-tiny security devices
A carbon nanotube (shown in brown) forms a bridge between two segments of DNA supported by gold contacts (yellow) attached to a silicon surface (green)
