Plasmonic DNA–gold nanorods film fabricated on the microposts. a, b POM images without and with a first-order retardation plate. The inset TEM image shows the dimensions of the PEG-modified gold nanorods. c–f Optical colour textures depending on the angle between a polariser and pulling direction show blue c, red e, and mixed colour d, f. Black scale bar represent 40 nm and white ones are 30 μm
