CHEM041 - Well-Controlled Deposition of Ag Nano-Cube Structure on Cu Substrates to Investigate Antimicrobial Efficiencies

The existing research on enhancing the antibacterial efficacy of metallic nanoparticles through bimetallic synergistic effects and its relationship with surface coverage remains limited. To address this gap, we aimed to design precise surface structures composed of both silver and copper. This approach allowed us to explore the connection between these bimetallic surfaces and their antibacterial properties within a film system, while also assessing the impact of surface coverage on this interaction. Our primary objective was to achieve a controlled deposition of silver nanoparticle structures onto copper substrates. Subsequently, we aimed to investigate the antibacterial efficiency of these structures to identify the optimal surface coverage of silver nanoparticles on copper thin film that would result in maximum antibacterial activity. The silver nanoparticles were synthesized and then deposited onto copper thin film with varying degrees of surface coverage. We subjected these deposited surfaces to antibacterial efficacy assessments using Escherichia coli as the test organism. The results were compared to control sets, which included copper surface controls and silver-silicon surface controls. This research aimed to shed light on the potential synergistic effects between silver and copper in enhancing antibacterial properties, with a focus on optimizing surface coverage for improved antibacterial activity. The bimetallic surfaces fabricated as a result of this research, combined with the insights gained, hold significant potential for various applications in industries where bacteria-sensitive surfaces are crucial for sanitization and where antimicrobial properties are required. Some of the potential applications include transportation packaging, medical equipment, food processing machinery, and cosmetics production. These applications highlight the broad potential of bimetallic surfaces for improving the safety and cleanliness of various products and environments. The research findings contribute to advancements in materials and technologies that can have a positive impact on public health and product quality in numerous industries.
