Abstract: Aspects of the disclosure relate to compositions and methods for amplifying and/or detecting one or more target nucleic acid sequences (e.g., a nucleic acid sequence of one or more pathogens) in a biological sample obtained from a subject. In some embodiments, the pathogens are viral, bacterial, fungal, parasitic, or protozoan pathogens, such as SARS-CoV-2 or an influenza virus. In some embodiments, the methods comprise isothermal amplification of a target nucleic acid and subsequent detection of the amplification products.

Abstract: Aspects of the present disclosure provide improved techniques for imaging a subject's retina fundus. Some aspects relate to an imaging apparatus that may be substantially binocular shaped and/or may house multiple imaging devices configured to provide multiple corresponding modes of imaging the subject's retina fundus. Some aspects relate to techniques for imaging a subject's eye using white light, fluorescence, infrared (IR), optical coherence tomography (OCT), and/or other imaging modalities that may be employed by a single imaging apparatus. Some aspects relate to improvements in white light, fluorescence, IR, OCT, and/or other imaging technologies that may be employed alone or in combination with other techniques. Some aspects relate to multi-modal imaging techniques that enable determination of a subject's health status.

Abstract: Provided herein, in some embodiments, are rapid diagnostic tests to detect one or more target nucleic acid sequences (e.g., a nucleic acid sequence of one or more pathogens). In some embodiments, the pathogens are viral, bacterial, fungal, parasitic, or protozoan pathogens, such as SARS-CoV-2 or an influenza virus. In one embodiment, a diagnostic system is provided comprising a control device configured to control one or more parameters and/or actions of a diagnostic test, and a test kit component comprising a physical encoding of control information for the control device. In one embodiment, the control device is configured to receive the control information of the physical encoding and perform one or more actions based at least in part on the control information. In one embodiment, the control device can control one or more temperatures at which a biological sample is to be processed as part of the diagnostic test.

Abstract: Provided herein, in some embodiments, are breakable swabs for sample collection. In some embodiments, the swabs may be used in rapid diagnostic tests to detect one or more target nucleic acid sequences (e.g., a nucleic acid sequence of one or more pathogens). In some embodiments, the pathogens are viral, bacterial, fungal, parasitic, or protozoan pathogens, such as SARS-CoV-2 or an influenza virus. The swab may include a stem portion for handling and a head portion for collecting and/or holding a sample. After sample collection, the head portion may be inserted into a reaction tube or any other sample-receiving device. The stem portion of the swab may then be separated or detached from the head portion along a breakable portion.

Abstract: A reagent carrier includes: a cap configured to fit on an opening of a reaction vessel; and a reagent confined by the cap. The cap may be configured to release the reagent when a user manipulates the cap while the cap is fitted on the opening of the reaction vessel. For example, the reagent may be released when the user twists the cap from a first position to a second position or when the user pushes on a surface of the cap. The cap may be configured to seal the opening of the reaction vessel when the cap is fitted on the opening of the reaction vessel. In some implementations, the cap may be a blister cap containing the reagent. In some implementations, the cap may include a cage containing the reagent. In some implementations, the cap may include a deformable structure containing the reagent.
