The recent bloom of nanomaterials has kindled the strong demand of a new cell inactivation technology that can replace the conventional cell inactivation process with high throughput, free chemicals usage, and outstanding efficacy to all pathogens to overcome the critically global issue -- microbial infection. Here, we construct a macroscopic carbon nanotube (CNT) sponge through a simple self-assembly method. Based on the technology of 1D nanostructure assisted electroporation, an electroporation disinfection cell (EDC) equipped with CNT sponge has achieved superior cell inactivation performance (<0.00001% microbe survival rate) within a contact time of 5 s at extremely low applied voltage (2 V), trace energy consumption (20 J L⁻¹), and outstanding durability (>60 min). The CNT sponge EDC can be easily powered by batteries or solar cells and shows the best energy consumption performance among all the cell inactivation technologies. Cell inactivation using CNT sponge EDC has great potential for practical applications.

碳纳米管海绵通过低压电穿孔实现高效和可靠的细胞灭活

近年来纳米材料的蓬勃发展引发了对新型细胞灭活技术的强烈需求，该技术可以以高通量，免费使用化学药品以及对所有病原体均具有出色的功效来替代传统的细胞灭活过程，从而克服至关重要的全球性问题-微生物感染。在这里，我们通过简单的自组装方法构造了宏观碳纳米管（CNT）海绵。基于一维纳米结构辅助电穿孔技术，配备了CNT海绵的电穿孔消毒池（EDC）在极低的施加电压（2 V）下接触时间5 s内，具有出色的细胞灭活性能（<0.00001％微生物存活率）。 ），痕量能耗（20 JL ^-1）和出色的耐久性（> 60分钟）。CNT海绵EDC可以很容易地由电池或太阳能电池供电，并在所有电池灭活技术中显示出最佳的能耗性能。使用CNT海绵EDC灭活细胞具有巨大的实际应用潜力。
