This optical microscope image shows the assembly of colloidal photonic crystals (green strips on the left side) onto a polymer microsphere.
The photonic materials are silica-coated magnetite nanoclusters and the polymer microspheres are made of Polyethylene Glycol Diacrylate. The sizes of microspheres are ∼100 µm.
