For this video, Kristiansen visualized his own blood cells with a microscopy technique called dark-field illumination—which is why the cells appear goldenish on a black background rather than red on a white background.

Similarly coloured regions correspond to areas with the same crystallographic orientation/thickness. h, Demonstration of the procedure for obtaining dark-field images of the grown seeds.

Substantial scattering can thus be expected to occur from the nanoantennas, as confirmed by the dark-field optical images shown in .

This is a dark-field image, highlighting surface details.
