| Sumario: | Silver (Ag) particles have sparked considerable interest in industry and academia, particularly for health and medical applications. Here, we present the “green” and simple synthesis of an Ag particle-based silicone (Si) thin film for medical device applications. Drop-casting and peel-off techniques were used to create an Si thin film containing 10–50% (<i>v</i>/<i>v</i>) of Ag particles. Electro impedance spectroscopy (EIS), X-ray diffraction analysis (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), and tensile tests were used to demonstrate the electrical conductivity, crystallinity, morphology-elemental, and mechanical properties, respectively. The oriented crystalline structure and excellent electronic migration explained the highest conductivity value (1.40 × 10<sup>−</sup><sup>5</sup> S cm<sup>−</sup><sup>1</sup>) of the 50% Ag–Si thin film. The findings regarding the evolution of the conductive network were supported by the diameter and distribution of Ag particles in the Si film. However, the larger size of the Ag particles in the Si film resulted in a lower tensile stress of 68.23% and an elongation rate of 68.25% compared to the pristine Si film. The antibacterial activity of the Ag–Si film against methicillin-resistant <i>Staphylococcus aureus</i> (MRSA), <i>Bacillus cereus</i> (<i>B. cereus</i>), <i>Klebsiella pneumoniae</i> (<i>K. pneumoniae</i>), and <i>Pseudomonas aeruginosa</i> (<i>P. aeruginosa</i>) was investigated. These findings support Si–Ag thin films’ ability to avoid infection in any medical device application. |
