Self-assembly of gold nanoparticles (AuNPs) can be used for several applications including sensors, lab on chips, and surface enhanced Raman scattering sensitive substrates. The architecture of the AuNPs aggregates is driven by the nanoparticle size, surface charge, and dielectric constant, and by the surface functionality of the substrate,...

All-cellulose composites with a potential application as food packaging films were prepared by dissolving microcrystalline cellulose in a mixture of trifluoroacetic acid and trifluoroacetic anhydride, adding cellulose nanofibers, and evaporating the solvents. First, the effect of the solvents on the morphology, structure, and thermal properties...
