摘要

In this research, utilized the pulse laser deposition (PLD) technique to craft pure SnO2 and gold-doped SnO2 thin films with varying concentrations 0.5, 1, and 3% Au. These novel films were applied on Si (111) substrates to evaluate their exceptional antibacterial efficacy against either gram-positive and gram-negative micro-organisms. Our thorough investigation examined the influence of adding on the surface morphology of deposited thin films employing X-ray diffraction (XRD), scanning electron microscopy (SEM), and atomic force microscopy (AFM). Our findings unveiled a clearly that crystallite size was multi crystalline for all prepared samples, correlation between the grain magnitude of the nanoparticles on the roof and the maxing concentration, underscoring that an upsurge in doping concentration led to a proportional increase in grain size. Notably, our research pinpointed the optimal doping concentration at a 3% Au to SnO2 ratio. Furthermore, delved into the effects of Au doping on the optical properties of the deposited films using UV-Vis-NIR spectrophotometry. The results of our extensive testing unequivocally demonstrated a high level of antibacterial activity against both gram-positive and gram-negative bacteria, showcasing the immense potential of utilizing Au: SnO2 structures in cutting-edge biomedical applications. Our research indicates that these structures possess unparalleled antibacterial properties and offer controlled nano-structuring achievable through the PLD technique.
