Is there a future for nanoscience and nanoscale technology?

Google is developing nanoparticles that the company hopes will catch early signs of disease, but are there potential drawbacks to the technology?

To stop identity thieves and counterfeiters, a group of researchers is looking for inspiration from an unlikely source: butterflies.

Money, gadgets and credit cards could soon have tiny, invisible anti-counterfeiting "fingerprints" embedded into them, making it pretty much impossible to falsify such objects, say scientists.

Tiny silver particles protect against microbes, but are they dangerous?

Crystals hit with infrared light could be the next generation of nanometer scale devices.

A nanotech-based vaccine that can be applied to the body's mucus membranes could be an effective, needle-less vaccination method, a new study in mice shows.
