Chlorine doping impact on the photocatalytic and antibacterial activity of sprayed In2S3 films
In this study, the surface chemistry and morphology, the photocatalytic and antibacterial potential of pure and chlorine doped indium sulfide thin films, produced by spray pyrolysis, were analyzed. The RMS roughness seems not to be significantly affected by the chlorine concentration in three of the doped films (around 12 nm). The roughness seems not to affect the characteristics of the films analyzed in this study. The samples presented a photocatalytic efficiency higher than 80%, but no correlation with the amount of Cl concentration was found. The antibacterial potential of the films was assessed against the multidrug-resistant bacteria Pseudomonas aeruginosa, responsible by serious infections, which are extremely difficult to treat in hospitals. The obtained results evidence an increase of antibacterial activity with the increase of Cl concentration. These results encourage further studies to support the potential of this material to be used in biomedical applications.

期刊介绍:
The material innovations on surfaces, combined with understanding and manipulation of physics and chemistry of functional surfaces and coatings, have exploded in the past decade at an incredibly rapid pace.
Superhydrophobicity, superhydrophlicity, self-cleaning, self-healing, anti-fouling, anti-bacterial, etc., have become important fundamental topics of surface science research community driven by curiosity of physics, chemistry, and biology of interaction phenomenon at surfaces and their enormous potential in practical applications. Materials having controlled-functionality surfaces and coatings are important to the manufacturing of new products for environmental control, liquid manipulation, nanotechnological advances, biomedical engineering, pharmacy, biotechnology, and many others, and are part of the most promising technological innovations of the twenty-first century.
