Blue, white and violet paints were produced using titanium dioxide
nanoparticles, 1H, 1H, 2H, 2H-perfluorooctyltriethoxysilane (PFOTES) in combination with either crystal violet, toluidine Blue O, or ethanol solutions.
Surfaces treated with the paints were highly water repellent, had anti-biofouling and potent photobactericidal activities. These paints could be beneficial for healthcare facilities, and would also be applicable in the home for decoration.
The white, blue and violet paints endowed surfaces with superhydrophobic and bactericidal properties.
- The surfaces showed high water repellency. Even after oil contamination, the surfaces kept water repellency and self-cleaning properties.
- The treated surfaces showed potent bactericidal activity under white light (99.99% reduction in bacteria).
The next step is to test the materials against recent clinical isolates of the post important hospital-acquired infectious agents and then test them in situ in healthcare facilities

I like that the classes are small coupled with the vast experience of the lecturer and their willingness to share their knowledge …
