Drug-resistant bacteria have been a problem in recent years, especially in hospital environments, resulting in a growing number of fatalities annually. As a result, alternative measures that can control these drug-resistant bacteria are need. The use of an antibacterial surface could be used to eliminate/reduce contact transfer of pathogenic bacteria. Nanoparticles that possess antibacterial properties, such as silver, have shown promise in controlling drug-resistant bacteria. However, the ability to synthesize such nanoparticles in a roll-to-roll process onto a large-area substrate has been a challenge. In this research, large-area antibacterial surfaces are produced using a roll-to-roll process. An aerosol deposition technique called Liquid Flame Spray (LFS) is used to deposit metal and metal-oxide nanoparticles onto different substrates to produce antibacterial surfaces. The LFS deposition process does not produce effluents, and nanoparticles can be produced at speeds exceeding 300m/min in a roll-to-roll process. Therefore, using the LFS technology to produce antibacterial surfaces would be beneficial in the overall fight against drug-resistant bacteria. Practical applications include roll-to-roll production of antibacterial paper and textiles.
