Tapping-mode AFM images of PAA brushes on mica after being spin-coated from aqueous solutions (2 µL) at pH 4 (A) and pH 9 (B) onto freshly-cleaved mica and allowed to dry under ambient conditions. TEM images of PAA brushes on a carbon-coated copper grid after being deposited from aqueous solution at pH 4, staining with uranyl acetate solution (1% wt.) (pH = 4), removal of the excess solution and allowing to dry under ambient conditions, collected at different magnifications (C, D).
