The functional support and advancement of our body while preserving inherent naturalness is one of the ultimate goals of bioengineering. Skin protection against infectious pathogens is an application that requires common and long-term wear without discomfort or distortion of the skin functions. However, no antimicrobial method has been introduced to prevent cross-infection while preserving intrinsic skin conditions. Here, we propose an antimicrobial skin protection platform copper nanomesh, which prevents cross-infectionmorphology, temperature change rate, and skin humidity. Copper nanomesh exhibited an inactivation rate of 99.99% for Escherichia coli bacteria and influenza virus A within 1 and 10 min, respectively. The thin and porous nanomesh allows for conformal coating on the fingertips, without significant interference with the rate of skin temperature change and humidity. Efficient cross-infection prevention and thermal transfer of copper nanomesh were demonstrated using direct on-hand experiments.

使用铜纳米网的抗菌第二皮肤

我们身体的功能支持和进步，同时保持内在的自然性是生物工程的最终目标之一。防止传染性病原体的皮肤保护是一种需要经常和长期佩戴而不会引起皮肤功能不适或扭曲的应用。然而，尚未引入抗菌方法来防止交叉感染，同时保持内在皮肤状况。在这里，我们提出了一种抗菌皮肤保护平台铜纳米网，可防止交叉感染形态、温度变化率和皮肤湿度。铜纳米网表现出 99.99% 的失活率大肠杆菌细菌和流感病毒 A 分别在 1 分钟和 10 分钟内。薄而多孔的纳米网允许在指尖上形成保形涂层，而不会显着干扰皮肤温度和湿度的变化率。使用直接手头实验证明了铜纳米网的有效交叉感染预防和热传递。
