Tannic acid (TA) is a natural polyphenolic compound that is known to exhibit many advantageous biological properties. TA acts as a weak acid due to the presence of multi-phenol groups and can assemble with positively charged polymers such as poly-L-lysine (PLL). To modify various substrates, we applied layer-by-layer assembly using a polyelectrolyte that is ionized according to pH conditions. We studied the surface properties such as thickness, wettability, composition, and morphology. Also, to consider the biological application of this nano-films, we conducted studies on cytotoxicity and biocompatibility.
