摘要:
Air filters formed from mats of protein-containing nanowires are provided. The nanowires are formed into a mat with pores that allow air to pass through while physically filtering particulate matter. The protein in the protein-containing nanowires also serves to chemically filter polluted air passed through the filter. Specifically, chemical functional groups from the many amino acids that comprise the protein of the protein-containing nanowire react with certain chemical pollutants (e.g., carbon monoxide and formaldehyde) in order to capture or otherwise neutralize the pollutant. Accordingly, the single nanofiber mat performs two filtering functions. Methods of filtering air using the provided air filters are also disclosed, as well as methods for making the air filters from protein-containing nanofibers.
摘要(中):
提供由含蛋白质纳米线的垫形成的空气过滤器。 纳米线形成具有允许空气通过的孔的垫,同时物理地过滤颗粒物质。 含蛋白质的纳米线中的蛋白质还用于化学过滤通过过滤器的污染空气。 具体来说,来自包含含蛋白质纳米线的蛋白质的许多氨基酸的化学官能团与某些化学污染物(例如一氧化碳和甲醛)反应,以捕获或以其他方式中和污染物。 因此,单个纳米纤维垫执行两个过滤功能。 还公开了使用所提供的空气过滤器过滤空气的方法,以及从含蛋白质的纳米纤维制造空气过滤器的方法。
