The versatility of ultrathin cellulose coatings on a flat silica substrate was demonstrated by a modification method with morphological distinction. Site-specific assembly of gold nanoparticles (AuNPs) on polystyrene domains on a cellulose film was accomplished via a straightforward method exploiting established physico-chemical phenomena: interfacial phase separation of polymers upon film deposition, site-specific protein adsorption on polystyrene, and electrostatic interaction. The obtained nanoparticle textures on cellulose films ranged from bicontinuous cellular networks to discrete disk-like assemblies. The approach can be seen as a platform for many similar 2D systems due to the general nature of the fundamental chemistry involved in the construction.
