Abstract: A nasal air filtration device for filtering air inhaled by a user is disclosed. The nasal air filtration device includes a pair of nostril tubes including a filter at one end and an ionic plate at other end. Each of the nostril tubes includes a cup having a plurality of openings. The nasal air filtration device includes a base tube coupled to the nostril tubes. The base tube includes an exhaust channel. The base tube includes a first housing having a battery and a second housing having a fan. In order to filter the air inhaled by a user, the nostril tubes are placed inside nostrils of the user. When the user inhales, the fan is operated to draw the air into the base tube, and the air is made to pass through the filter and the ionic plate provided at the nostril tubes into the nostrils via the openings. When the user exhales, the air is released into the atmosphere through the exhaust channel via the nostril tubes.

Abstract: A system and method for performing an assay for target analytes includes a sampling-device holder interface and a quantifier. The sampling device has a sampling portion and a reading portion containing a chemiluminescent reagent. The interface has a sampling-device holder and a light detector. The holder has a housing having an enclosure with a channel and a base plate with an opening. The base plate and the enclosure houses a slidable tray. The tray has a compartment adapted to seat the sampling device and an opening extending through the compartment. The reading portion is aligned with the tray opening. When the tray is closed, the tray opening is also aligned with the base plate opening, exposing the reading portion. Once the sampling portion is exposed to a sample suspected of containing the target analyte, at least one carrier liquid is introduced, if needed, to the sampling portion to transport any target analyte to the reading portion by dispersion.

Abstract: A test strip, a device incorporating the test strip and a method for use of the test strip within the device detecting an analyte in a solution or bodily fluid are disclosed. The test strip was three zones, a reaction zone coated with a substance that binds the analyte, a sample zone with a region for addition of the sample of solution or fluid, and a detection region zone with a region coated with detection reagent. An absorbent pad underlies the reaction zone. The reaction zone is a small membrane and is physically in contact on its upper surface with both the sample zone and the detection zone. The test strip is incorporated into a device which includes a sample collection/transferring device, a housing for holding the test strip, and a container for holding solvent solutions at both outer ends of the test strip such that the solvent solutions can come into contact with the outer ends of the test strip when pressure is applied to the ends.

Abstract: A method which utilize chemiluminescence for analyte detection and the detection of bacteria on surfaces. The method uses a device comprising a sampling portion made of a first adsorbent material, a container, and a second adsorbent material located within the container. The sampling portion collects analytes from a test sample which includes a surface or volume of a liquid. The second adsorbent material holds one or more chemiluminescent components including luciferase enzyme and cofactors in a dry state. In a preferred embodiment, the sampling portion is swabbed over a suspected contaminated surface. A bacteriolytic solution is then added to the adsorbent and releases ATP from any bacteria present. The ATP diffuses into the second adsorbent and mixes with the reagents therein to produce detectable light.

Abstract: Improved devices for collecting and analyzing samples of aqueous solutions, body fluids, sewage or fecal matter to be used in detecting microbes and microbial byproducts. A device in accordance with the invention comprises a body including an internal channel having an entryway, a solute chamber connected to the entryway, a solute-adding mechanism operatively connected to the solute chamber, a window in the body that allows viewing of a portion of the channel, and an aperture in the body that opens to the channel; a bendable tang connected to the body; and a sample collection unit attached to the tang.
