US 2023/0408121 A1 · SYSTEMS AND PROCESSES FOR DETECTING AEROSOLIZED VIRAL LOADS

Abstract

Systems are provided for measuring the conductivity of a liquid medium or a gel-like solid or semi-solid medium in which airborne viruses have been forced to fall; and monitoring the resulting changes in the capacitive and resistive properties of the medium due to colloidal electrochemistry of the viral particles using a range of frequency detection techniques. Various control parameters can be implemented to facilitate the estimation of very low viral concentration levels in the medium. The control parameters can include, for example, the level of the medium, the temperature of the medium, statistical classification parameters, and the addition of a buffer to the medium to amplify the signal.

Dependent claims

A system for detecting the presence of a viral load in an airspace, comprising:

a conductivity probe;
a frequency generator communicatively coupled to the conductivity probe and configured to, during operation, apply an alternating voltage to the conductivity probe while the conductivity probe is immersed at least in part in a medium comprising a solvent, and particles sampled from the airspace and suspended in the solvent, wherein the first alternating voltage causes an alternating current to flow between the conductivity probe and the frequency generator;
and
a computing device communicatively coupled to the frequency generator and configured to, during operation, determine a viral load in the medium based on a frequency response of the conductivity probe to the alternating voltage applied thereto.
