In this study, silver nanoparticles were prepared using a microplasma-aided approach without the need for traditional chemical reductants, and then compounded with a gemini cationic surfactant to form a nano-surfactant system with improved antibacterial activity and stability. The synergistic effects of the compounding system were studied, demonstrating well-dispersed AgNPs in the presence of the surfactant and enhanced antibacterial activity.
The compounding of surfactants with specific nanomaterials may result in a system of multi-functionalities. In this work, silver nanoparticles (AgNPs) were prepared by a microplasma-aided approach, where traditional chemical reductants were not required. The influence of plasma conditions and parameters on the product (e.g. composition, structure) was studied via characterization techniques like UV-Vis, SEM, TEM, EDX, XRD, SAED, OES and HRTEM. Results showed that crystalline AgNPs of high purity can be directly obtained in one step, without any chemical reducing agents. Meanwhile, a gemini cationic surfactant (Tetramethylene-a,v-bis(lauryloxyethyl dimethyl lammonium bromide)) of superior surface activity and well antibacterial property was synthesized, and then compounded with the plasma-generated AgNPs to form a nano-surfactant system. By evaluating their antibacterial activity against E. coli and S. aureus, the synergistic effects of the compounding system were studied. It was demonstrated that AgNPs were well-dispersed in the presence of the gemini cationic surfactant, and the nano-surfactant compounding system has improved antibacterial activity as well as good stability.
