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

<table>Dynamic response of three sensors consisting in
a (PAH+NR/PAA)25 fabricated at three different pH values. S01 was fabricated at
pH 7, S02 at pH 3, and S03 at pH 4. S03 response was found to be the most
sensitive and stable signal.</table>
