摘要

The technique of plasma jet has gained significant importance in the synthesis of nanoparticles (NPs), because it provides high efficiency in preparing nanoparticles and it is considered a clean and environmentally friendly sustainable technology because it does not require harmful chemicals in addition to the unique chemical reactions that can produce nanoparticles with new and innovative properties. The resulting material was characterized by its high purity when comparing with traditional chemical methods; furthermore, this technique allows variation of their morphology and sizes. In this work, cold plasma was used to synthesize silicone nanoparticles; this method is novelty for producing silicone nanoparticles by prepared from a bulk silicon target submerged in deionized water using the plasma jet process at various times of exposure (3, 5, and 7) min. The produced silicone nanoparticles were investigated by numerous ways, including X-ray diffraction (XRD), X-ray energy-dispersive spectroscopy (EDS), atomic force microscopy (AFM), and scanning electron microscopy (SEM), zeta potential, contact angle, and study the activity on S. aureus bacteria. The produced particles exhibit a comparatively diminutive average size, varying between 11.2 and 7.4 nm for 5 and 7 min while the exposure time is 3 min, it is amorphous, and it had semispherical shape. The prepared nanoparticles have a high stability by zeta potential measurement and a high antibacterial activity for S. aureus when increasing the exposure time.
