AFM characterization of spin coated carboxylated polystyrene nanospheres/xyloglucan layers on mica and silicon

► We present thin film of carboxylated polystyrene nanosphere and xyloglucan layer. ► Nanospheres diameter is independent of component proportions in the mixture. ► Nanospheres diameter dependent of the angular chuck speed. ► Nanosphere diameter on silicon compared to mica is much smaller. ► Behavior similar to spin-coated colloidal dispersions.
