Modification of halloysite lumen with dopamine derivatives as filler for antibiofilm coating

Abstract

All characterization methods proved the selectivity of the modification and the increased hydrophobicity of the lumen. In particular ²⁷Al solid state nuclear magnetic resonance (NMR) spectra showed a upfield shift of the Al signal. Studies on the antibiofilm properties highlighted different activities according to the length of perfluoroalkyl chains of organic molecules as proved by ¹⁹F solid state NMR spectra. The synthetized materials were promising for future application as coatings on medical implants.
