Device and method for real-time detection of aeropathogens

Device for real-time detection of aeropathogens comprising:

• an aerosampler comprising (i) an air inlet to intake a sample of air comprising a plurality of droplets, wherein the plurality of droplets comprises aeropathogens, and (ii) at least one collector tube to receive the sample of air and to collect the plurality of droplets, and capable of collecting simultaneously two size distributions of the aeropathogens,
• a microfluidic system comprising at least one container, piping and at least one micro pump for flowing a liquid,
• wherein the at least one container contains wetting liquid, wherein the at least one container is fluidly connected to the at least two collector tubes to supply the wetting liquid to wet inner walls of the at least two collector tubes,
• at least one viral detection chamber fluidly connected to the aerosampler to receive the plurality of droplets and to detect the aeropathogens in the plurality of droplets,
• wherein the at least one viral detection chamber comprises at least one working electrode and at least one counter electrode, wherein the at least one working electrode comprises one or more compounds that specifically bind to one or more portions of the aeropathogens,
• at least one electronic detection system electrically connected to the at least one viral detection chamber,
• wherein data receivable from the at least one electronic detection system is processed electronically,
• wherein the aerosampler further comprises:
• a dust collector for collecting dust present in the sample of air, and
• wherein the at least two collector tubes are two centrifugal collector tubes oriented in a direction of flow of the sample of air,
• wherein a first tube of the two centrifugal collector tubes is positioned closer to the flow of the sample of air than a second tube of the two centrifugal collector tubes, such that the sample of air enters the first tube and the second tube in sequence,
• wherein the plurality of droplets comprises a first set of droplets having a diameter of between two microns and 10 microns, and a second set of droplets having a diameter of up to five microns,
• wherein the first tube receives a first portion of the sample of air and the wetting liquid, thereby collecting the first set of droplets, and
• wherein the second tube receives a second portion of the sample of air and the wetting liquid, thereby collecting the second set of droplets.
