They comprise: (I) 0.3 mm thick CORNING® GORILLA® GLASS substrate, (II) dewetted Cu nanoparticles (NPs) from a UTMF of 3.5 nm Cu, (III) SiO2 embedding layer and (IV) Easy-To-Clean (ETC) Fluorosilane coating. Dimensions are not in scale. The difference in shape (e.g., contact angle) of the particles reflects the real images, an example being that shown in Fig. 2.
