新型冠状病毒大流行(新冠肺炎)要求在全球范围内增加口罩的使用，以限制病毒的空气传播。全球对个人防护装备的需求有时会导致公众口罩短缺，因此临时口罩变得司空见惯。由冠状病毒2型引起的严重急性呼吸综合征(SARS-CoV-2)的球形颗粒尺寸为~97 nm。然而，这种病毒的空气传播需要排出直径通常为0.6-500 微米的飞沫(通过咳嗽、打喷嚏、呼吸和说话)。在这篇文章中，我们提出了一种面罩，它被设计成有效地捕捉SARS-CoV-2，同时为佩戴者提供不折不扣的舒适性和透气性。在此，我们描述了一种材料方法，该方法使用附着在棉纤维上的无定形二氧化硅微球来捕获生物气溶胶，包括SARS CoV-2。这已被证明用于捕获气雾化蛋白质(细胞色素c、肌红蛋白、泛素、牛血清白蛋白)和气雾化灭活SARS CoV-2，平均过滤效率为~93%，对透气性的影响最小。对口罩的需求显著增加，但实现透气性和有效过滤之间的平衡是具有挑战性的。在这里，作者报告了一种用于捕捉生物气溶胶的改性棉口罩。
The novel coronavirus pandemic (COVID-19) has necessitated a global increase in the use of face masks to limit the airborne spread of the virus. The global demand for personal protective equipment has at times led to shortages of face masks for the public, therefore makeshift masks have become commonplace. The severe acute respiratory syndrome caused by coronavirus-2 (SARS-CoV-2) has a spherical particle size of ~97 nm. However, the airborne transmission of this virus requires the expulsion of droplets, typically ~0.6–500 µm in diameter (by coughing, sneezing, breathing, and talking). In this paper, we propose a face covering that has been designed to effectively capture SARS-CoV-2 whilst providing uncompromised comfort and breathability for the wearer. Herein, we describe a material approach that uses amorphous silica microspheres attached to cotton fibres to capture bioaerosols, including SARS CoV-2. This has been demonstrated for the capture of aerosolised proteins (cytochrome c, myoglobin, ubiquitin, bovine serum albumin) and aerosolised inactivated SARS CoV-2, showing average filtration efficiencies of ~93% with minimal impact on breathability. There has been a significant increase in the demand for face masks, but achieving a balance of breathability and effective filtration is challenging. Here, the authors report a face mask of modified cotton for the capture of bioaerosols.
