Bright colors produced by laser heating

Most of the colors on today's paper and fabric are made using dyes or pigments. But colors can also be produced by modifying a material's surface at the nanoscale, causing the surface to reflect or scatter different frequencies ...

Ultra-sensitive sensor with gold nanoparticle array

Scientists from the University of Bath (UK) and Northwestern University (USA) have developed a new type of sensor platform using a gold nanoparticle array, which is 100 times more sensitive than current similar sensors.

Holographic color printing for optical security

Researchers from the Singapore University of Technology and Design (SUTD) have invented a new type of anti-counterfeiting technology called holographic colour prints for securing important documents such as identity cards, ...

Scientists move quantum optic networks a step closer to reality

Scientists have moved quantum optic networks a step closer to reality. The ability to precisely control the interactions of light and matter at the nanoscale could help such a network transmit larger amounts of data more ...

Holey graphene as Holy Grail alternative to silicon chips

Graphene, in its regular form, does not offer an alternative to silicon chips for applications in nanoelectronics. It is known for its energy band structure, which leaves no energy gap and no magnetic effects. Graphene antidot ...
