The present invention generally relates to air sampling of biological compounds. Specifically, the present invention relates to a device and method for sampling the ambient air for detecting microbial propagules, microbial propagules being any spore, vegetative cell, or virion of microbiological origin including all bacteria, fungi, viruses, protozoans, molds, slime molds, chlamydospores, hyphae, and cysts.

A measurement device includes: a capturing part for causing a liquid to capture detection target particles contained in a gas and causing a fluorescent substance specifically bondable to the detection target particles to be bonded to the detection target particles; a droplet forming part for forming aerosol-like droplets from the liquid; and a measurement part for irradiating light onto the droplets and measuring the fluorescence intensity of the droplets. The capturing part includes a cyclone which swirls the gas introduced from a gas introduction part in a circumferential direction, separates the detection target particles toward a wall surface of the cyclone body under a centrifugal force, introduces the liquid from the liquid introduction part, causes the liquid to capture the detection target particles separated toward the wall surface and continuously supplies the liquid to the droplet forming part.

A biosensor and virusometer allows continuous, real-time detection of viral particles of pathogens, especially SARS-COV-2, both in indoor and outdoor air and in liquid samples in which the pathogen(s) have been collected. The biosensor includes a quartz crystal microbalance coated with a layer having one or more antibodies specific to one or more pathogens to be detected. A first virusometer is described, including an aerosol collector, which makes it possible to increase the concentration of pathogens before taking them to the biosensor. A second virusometer has a receptacle, divided into a first cavity wherein air exhaled by a user is collected and concentrated, and a second cavity wherein the biosensor is arranged.

Disclosed are an apparatus for analyte sampling, and a method of analyte sampling and an analyte sampling analysis system using the same. The apparatus includes a spray unit to receive a trapping solution and an analyte sample, and to mix and spray the analyte sample and the trapping solution of an aerosol state together, a spray chamber to provide a space to primarily trap an analyte material, which is contained in the analyte sample, in the trapping solution of the aerosol state, a trapping tube to secondarily trap the analyte material, which is not trapped in the spray chamber, by receiving the analyte sample and the trapping solution in the aerosol state from the spray chamber and mixing the trapping solution with the analyte sample, a trapping container to receive the trapping solution having the analyte material trapped therein through the trapping tube, and a sample transfer unit to feed purge gas into the trapping container to transfer the trapping solution having the analyte material trapped therein to an analysis unit through a sample transfer line by the purge gas.

An aerosol biological collector/analyzer, and method of collecting and analyzing an aerosol sample for diagnosis is provided. In particular, the current invention is directed to an airborne aerosol collection and bacterial analysis system and method, capable of collecting an airborne aerosol sample and preparing it for analysis via aerodynamic shock in a single-step.

An apparatus and process of using existing process water sources such as cooling towers, fountains, and waterfalls is provided in which the water sources are utilized as monitoring system for the detection of environmental agents which may be present in the environment. The process water is associated with structures and have an inherent filtering or absorbing capability available in the materials and therefore can be used as a rapid screening tool for quality and quantitative assessment of environmental agents.

We describe apparatuses, systems, method, reagents, and kits for conducting assays as well as process for their preparation. They are particularly well suited for conducting automated sampling, sample preparation, and analysis in a multi-well plate assay format. For example, they may be used for automated analysis of particulates in air and/or liquid samples derived therefrom in environmental monitoring.

Apparatus and methods for sampling air-borne particles. According to one embodiment a nozzle is used to generate a jet of fog that includes a gas and liquid droplets. The jet of fog is formed by the nozzle in a way to cause particles in the air surrounding the jet of fog to be drawn into the jet of fog and to further cause the particles to aggregate with the liquid droplets inside the jet of fog. A sample collecting surface is located opposite and spaced apart from an outlet of the nozzle. The sample collecting surface is preferably sloped so that the liquid sample can be forced by gravity off the collecting surface and into a liquid sample container. Inside the jet of fog and on the sample collection surface the liquid droplets merge with one another to form larger sized droplets that are collectable in the liquid sample container.
