Nanobrick

Nanobrick is a South Korean advanced-materials company in Pyeongtaek, built on an active nano platform: photonic-crystal particles steered by magnetic and electric fields so a surface changes colour, pattern or transparency on command. Founded in 2007 and listed on KOSDAQ as 286750, it commercialised M-Tag, a magnetically switchable anti-counterfeiting label, and now trades as NanoSilikhan Advanced Materials, carrying the platform into silicon anodes for batteries.

E-skin Anycolor introduced the company to designers: an electrophoretic film that needs a single coloured nanoparticle suspension rather than the two or more layers of conventional e-paper, so a panel or object can switch to almost any tone in custom sizes. Nanobrick pitched it as a slow, low-energy colour change for architecture rather than another lit screen.
