Data for: Fabrication and characterization of antibacterial coatings using an amphoteric condensed tannin,Tanfloc

This dataset presents comprehensive information on the development and
characterization of antibacterial polyelectrolyte multilayer (PEM)
coatings incorporating tanfloc, a plant-derived condensed tannin polymer
with inherent antimicrobial properties. The dataset encompasses
experimental data related to the fabrication of PEMs using tanfloc as
either a polyanion or a polycation, expanding the versatility of this
amphoteric polymer in PEM coatings. Typically, PEMs are formed by
combining a polycation and a polyanion with complementary ionic groups.
However, the unique amphoteric nature of tanfloc allows for the creation
of PEMs utilizing only one of its functional groups, leaving the other
functional group available for imparting antibacterial activity. The
dataset includes details on the assembly of tanfloc-containing PEMs
employing various counter-polyelectrolytes, including three poly-anionic
glycosaminoglycans with varying charge densities, as well as the
polycations N,N,N-trimethyl chitosan and polyethylenimine. The
layer-by-layer assembly of PEMs is monitored using in situ
Fourier-transform surface plasmon resonance (FT-SPR), confirming stable
layer-by-layer construction. Surface chemistry is assessed through X-ray
photoelectron spectroscopy (XPS). Furthermore, this dataset provides
insights into the biocompatibility of tanfloc-containing PEMs,
demonstrating their support for mammalian cells. Most notably, the dataset
includes extensive data on the antiadhesive and antibacterial properties
of these coatings against common implant-associated pathogens, such as
Staphylococcus aureus and Pseudomonas aeruginosa. The antibacterial
effects observed are attributed to electrostatic interactions and the
polyphenolic nature of tanfloc.
