Study and Optimization of Self-Assembled Polymeric Multilayer Structures with Neutral Red for pH Sensing Applications

<table>Left: the bars show the bilayer thickness as
the pH of the polyelectrolyte solutions was varied. Right: the dotted line is
the square roughness of the surface of the (PAH+NR/PAA)25.</table>
