The present disclosure relates to a specimen collection device comprising ventilation means for drying a collected specimen. The device further comprises a cassette into which the specimen collected is secured to maintain evidentiary chain of cus tody requirements while providing unobstructed access to a collected specimen for automated analysis. Methods of using the device are also provided.

A method for optically reading information encoded in a microfluidic device, the microfluidic device including an input microchannel, microfluidic modules, and sets of nodes. Nodes of a first set connect the input microchannel to one of the microfluidic modules, and nodes of a second set connect the one of the microfluidic modules to another to form an ordered pair of the microfluidic modules, where the nodes of the first and second sets have different liquid pinning strengths. A liquid loaded into the input microchannel causes an ordered passage of the liquid through each of the microfluidic modules in an order determined by the liquid pinning strengths of the nodes. The passage of the liquid produces an optically readable dynamic pattern which evolves in accordance with the ordered passage of the liquid through the device.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for a forensic imaging apparatus for documentation, forensic analysis, and reporting of bullet casings. In one aspect, an assembly includes an adaptor for attaching the assembly to a user device, a housing defining a barrel extending along an axis and attached to the adaptor and having an opening that is sufficiently large to receive a firearm cartridge casing, and a holder for holding the firearm cartridge casing at an illumination plane within the barrel. Light sources are arranged within the housing and to direct light to illuminate the illumination plane, the light sources including a first light source arranged to illuminate the illumination plane at a first range of glancing incident angles.

A method of reducing quality problems associated with patient sample collection and delivery is provided. It is possible that the method can provide a chain of custody process to better track a sample from the initial point of sample collection to the final point of sample testing. Such a method can also include providing an alert to indicate a potential problem with the quality of the diagnostic test result when a measured parameter exceeds a threshold.

A trace evidence material (TEM) collection device is disclosed that enables crime scene investigators to quickly and easily collect, analyze, annotate, securely store and electronically distribute images of large amounts of trace evidence materials and related crime scene information while also helping to comply with required trace evidence recovery procedures and documentation requirements. The TEM collection device includes a reusable handle and cassette drive mechanism, which may be used with a plurality of single-use cassettes. Each cassette includes a TEM collection media (such as a collection tape or swabbing pads attached to a substrate) that when moved across a surface is capable of collecting TEMs located on the surface. Preferably, each cassette also includes a sealing assembly that seals the TEM collection media after collection of the TEMs so as to preserve the collected TEMs.

The system in at least one embodiment provides a tamper evident specimen sample lock that in a further embodiment includes an embedded storage medium. They system and method in at least one embodiment allows for efficiently and securely creating, maintaining, identifying, tracking, and controlling inventories (either prospective or retrospective) of biological and chemical sample containers and their contents, while eliminating potential loss and degradation associated with handling the samples. The system in at least one embodiment provides a sample container tray or cryogenic box having one or more integrated RFID readers within an associated smart lid that sense RFIDs associated with the individual samples thereby eliminating the need to remove, visually inspect, and/or handle the samples.

Described herein are a wearable apparatus and methods for detecting the presence of a targeted substance in a liquid. For example, the wearable apparatus can be a fingernail that detects illicit drugs in a beverage. The wearable apparatus comprises a detection layer comprising an indicator that is configured to display a signal upon the detection of an interaction with the targeted substance. In some examples, the wearable apparatus can include a lateral flow assay.

Described herein are apparatus and methods for detecting substances of abuse or other analytes in liquids. For example, the apparatus and methods described herein can be used for real-time detection of analytes, such as substances of abuse. The methods comprise providing a detection area comprising a chromatographic membrane capable of receiving the liquid and allowing for migration of the liquid, the chromatographic membrane comprising an anti-analyte antibody-particle conjugate, an analyte-conjugate protein at a test line; exposing at least the first location of the apparatus to the liquid; and determining whether an interaction between the analyte-conjugate protein and the liquid occurs to detect the presence of the analyte. The chromatographic membrane may further comprise an anti-species antibody at a control line. Specific buffers are disclosed, and these buffers may be used in the preparation of the apparatus to overcome challenges associated with miniaturization and challenges associated with exposure to beverages.

A technology capable of easily preventing erroneous reuse of a used cartridge is provided.

Provided is a cartridge at least including a sample holding unit for holding a sample containing a detection target substance to be detected by a detecting device, and an irreversible variable portion capable of irreversibly physically changing arranged in a position corresponding to a distinguishing unit of the detecting device when being installed in the detecting device.
