Large-scale nanofilms were of great interest in the field of nanophotonics, mainly due to their unique optical properties. Two dimensional (2D) large-scale gold nanofilm was fabricated by an interface self-assembly method based on sodium citrate-capped gold nanoparticles (AuNPs). AuNPs was firstly characterized by UV-vis spectra and transmission electron microscopy methods. The prepared large-scale gold nanofilm was characterized by scanning electron microscopy technology. We expected this method and the prepared nanofilm would apply in biosensors and functionalized optical devices.
