在共聚物乳胶漆中加入结晶紫、亚甲基蓝、红花红O和2纳米金纳米颗粒，制备了三种独立的涂料体系；三染料体系（结晶紫、亚甲基蓝、藏红花红O和2nm金纳米粒子）、双染料体系（结晶紫、亚甲基蓝和2nm金纳米粒子）和单染料体系（藏红花红O和2nm金纳米粒子）。用紫外可见吸收光谱、红外光谱和x射线光电子能谱对改性聚合物进行了表征。这三种涂料体系在水性条件下具有中等稳定性，涂料聚合物中的染料浸出到周围水溶液中的数量有限。将三种涂料系统暴露在28w的白光光源下，可引起金黄色葡萄球菌和大肠杆菌的致死性光敏反应。此外，三染料和双染料体系在黑暗条件下对金黄色葡萄球菌的杀伤效果均为4 log，而红花素O和2 nm金纳米颗粒体系对金黄色葡萄球菌的杀伤效果为1.5 log。
Crystal violet, methylene blue, safranin O and 2 nm gold nanoparticles were incorporated into a copolymer emulsion paint and three separate paint systems were prepared; a three-dye system (crystal violet, methylene blue, safranin O and 2 nm gold nanoparticles), a two-dye system (crystal violet, methylene blue and 2 nm gold nanoparticles) and a one dye system (safranin O and 2 nm gold nanoparticles). The modified polymers were characterised by UV-Vis absorbance spectroscopy, IR spectroscopy and X-ray photoelectron spectroscopy. The three paint systems were moderately stable under aqueous conditions, with a limited amount of leaching of the dyes from the paint polymer into the surrounding aqueous solution. Exposure of the three paint systems to a 28 W white light source induced the lethal photosensitisation of both Staphylococcus aureus and Escherichia coli. Moreover, both the three-dye and two-dye systems resulted in a 4 log kill against S. aureus under dark conditions, and a 1.5 log dark kill was obtained by the safranin O and 2 nm gold nanoparticle system.
