Iron-coated polymer films with high antibacterial activity under indoor and outdoor light, prepared by different facile pre-treatment and deposition methods

César Pulgarin, Sami Rtimi, Laura Victoria Suárez Murillo, Ania Schärer, Stefanos Giannakis

In the present work, we study the fabrication of self-cleaning antibacterial surfaces, active under indoor or outdoor light. In order to obtain the highest activity with the lowest complexity we assess mild conditions of preparation (temperatures), pre-tre ...
