# s-chem: bimetallic nanodot arrays and electrochemical bias to ‘Chameleon’ plasmonic skin camouflage

<< [AA] have developed a way to produce colour-tuneable plasmonic metal nanostructures. They consist of a layer of nano-sized gold domes coated with a gel containing silver ions, all of which are sandwiched between two electrodes. Applying a positive voltage between the electrodes binds the silver ions to the gold domes, changing the characteristic plasmon reflectivity from red to green and finally blue; reversing the voltage takes the reflectivity back to the red end of the spectrum. >>
