Preventing nosocomial infection is a major unmet need of our times. Existing air decontamination technologies suffer from demerits such as toxicity of exposure, species specificity, noxious gas emission, environment-dependent performance and high power consumption. Here, we present a novel technology called "ZeBox" that transcends the conventional limitations and achieves high microbicidal efficiency. In ZeBox, a non-ionizing electric field extracts naturally charged microbes from flowing air and deposits them on engineered microbicidal surfaces. The surface's three dimensional topography traps the microbes long enough for them to be inactivated. The electric field and chemical surfaces synergistically achieve rapid inactivation of a broad spectrum of microbes. ZeBox achieved near complete kill of airborne microbes in challenge tests (5-9 log reduction) and [Formula: see text] efficiency in a fully functional stem cell research facility in the presence of humans. Thus, ZeBox fulfills the dire need for a real-time, continuous, safe, trap-and-kill air decontamination technology.
预防医院感染是我们这个时代尚未满足的主要需求之一。现有的空气消毒技术存在着暴露毒性、物种特异性、有害气体排放、性能依赖环境和高功耗等缺点。在这里,我们提出了一种名为“ZeBox”的新技术,它超越了传统的局限性,实现了高效的杀菌效果。在 ZeBox 中,非电离电场从流动的空气中提取自然带电的微生物,并将其沉积在工程化的杀菌表面上。表面的三维形貌足以捕获微生物并将其灭活。电场和化学表面协同作用,快速灭活广谱微生物。在挑战测试中,ZeBox 实现了空气中微生物的近乎完全杀灭(减少 5-9 个对数),并且在有人存在的情况下,在一个功能齐全的干细胞研究设施中,效率达到了[Formula: see text]。因此,ZeBox 满足了对实时、连续、安全、捕获和杀灭空气消毒技术的迫切需求。
