Abstract

In this paper, the authors describe an electromagnetic-hydrodynamic (EMHD) model of the airborne microbiological agent detection concept for the design of a sensor to identify the presence of airborne bacteria and viruses. Based on the model and a laboratory test, a methodology was proposed for the capture and subsequent detection of low-concentration bacterial and viral agents in airborne aerosols. A physical-biological approach was proposed to detect microorganisms based on their physical properties. The principle was validated in the laboratory on samples of defined concentrated water aerosols of Bacillus subtilis (BS) and feline infectious peritonitis virus (FIVP). Repeated tests with different concentrations were performed in the laboratory conditions.

摘要

在本文中，作者描述了一种用于设计传感器以识别空气中细菌和病毒存在的空气传播微生物剂检测概念的电磁流体动力学（EMHD）模型。基于该模型和实验室测试，提出了一种用于捕获并随后检测空气中气溶胶中低浓度细菌和病毒剂的方法。提出了一种基于微生物物理特性来检测微生物的物理生物学方法。该原理在实验室中针对枯草芽孢杆菌（BS）和猫传染性腹膜炎病毒（FIVP）的特定浓度水气溶胶样本进行了验证。在实验室条件下对不同浓度进行了重复测试。
