“…A variety of charged moieties have be employed for the construction of LBL assemblies, including polycations, such as, poly(diallyldimethylammonium chloride) (PDDA), poly(ethyleimine) (PEI) and poly(allylaminehydrochloride) (PAH) [21][22][23][24][25][26][27][28][29], transition metal complexes [16], dye molecules such as Methylene Blue, Thionin, Azure A, Brilliant Cresyl Blue and Nile Blue chloride [30], metallodendrimers [31], dendrimers [18], metalloporphyrins [32] and nanoparticles [33]. The growth of such films on solid surfaces has been monitored by cyclic voltammetry [16,20,22,31,[34][35][36], UV -Vis absorption spectroscopy [16,20,22,30,35,36] or impedance spectroscopy [20].…”
