A nice seed crystal is glued to a piece of monofilament ... cleaner would be a good next step, as would perhaps growing even larger crystals.

Liquid-phase TEM video of layer-by-layer growth of a crystal with smooth surface from gold concave nanocubes. Surface particles on the growing crystal are tracked (center positions overlaid with ...

The rest of the process happens more or less naturally, as crystals begin to form in the saturated solution. And boy, did they grow — long, prismatic lime-green crystals, with a beautiful ...
