The transmission of bacteria through cooking surfaces, the handles of hot plates, and cookware that is not cleaned frequently can pose a problem. In this study, a copper ion-based mixed solution (CBMS) containing only inorganic ions with controlled acidity was assessed as a new antibacterial and antiviral agent. We analysed the structure of the precipitates, and various deposits measuring a few micrometres were observed on the substrates. We have defined these deposits as strongly bonded scaly copper dispersion (SBSCD) structures.The antibacterial copper component of the liquid agent changed over time after application; this mechanism appears to be responsible for the maintenance of antibacterial performance.CBMS demonstrates high safety for the human body and can be applied to stainless steel materials used in kitchens and tables. It exhibits a sustained antibacterial effect over time, and its antibacterial properties can be continuously maintained.
细菌通过烹饪台面、热板把手以及不经常清洁的炊具传播会引发问题。在本研究中，一种仅含无机离子且酸度可控的基于铜离子的混合溶液（CBMS）被评估为一种新型抗菌抗病毒剂。我们分析了沉淀物的结构，在基材上观察到了各种几微米大小的沉积物。我们将这些沉积物定义为强结合鳞状铜分散体（SBSCD）结构。液体剂中的抗菌铜成分在应用后随时间发生变化；这种机制似乎是维持抗菌性能的原因。CBMS对人体显示出高安全性，可应用于厨房和餐桌所用的不锈钢材料。它随时间呈现持续的抗菌效果，其抗菌性能能够持续保持。
