Photonic Crystals in Anticounterfeiting

Photonic crystals (PCs) are optical nanostructures that affect the propagation of light by the periodic variation in their refractive index. As counterfeiting techniques become ever more sophisticated, PCs offer physically unclonable functions (PUFs) due to their defect-sensitive optical behaviour and structural colours that cannot be reproduced accurately by traditional printing or scanning techniques.

Seamless Drum Moulds with Nano and Microscale Structures

New technology from US-based startup SMS, called ‘Nanocoining’, is helping to bring nano- and microscale patterns to the industrial scale. The technology creates seamless cylindrical drum moulds for roll-to-roll nanoimprint processes with a patterning rate of up to 2 square inches (2,500mm2) per second – more than 500 times faster than typical electron-beam tools.
