Collection devices and kits for biological sample collection include a biologic sample collection device having a hydrophilic swab matrix that includes a modified polycaprolactone (PCL). Methods of production and use thereof are also described herein. The biologic sample collection devices, kits and methods described herein are used to collect a biologic sample (e.g., blood, buccal cells, etc.) and to enable extraction of nucleic acids (e.g., DNA) from that biologic sample so that the nucleic acids can be analyzed (e.g., sequencing and subsequent analyses of DNA).

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.

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 custody requirements while providing unobstructed access to a collected specimen for automated analysis. Methods of using the device are also provided.

The present invention is related to a method for obtaining dental pulp and root cement in the forensic dentistry field, wherein the method comprises the steps of: (a) obtaining a tooth; (b) taking a digital radiography to the tooth; (c) external rehydrating of the tooth; (d) perforating the rehydrated tooth; (e) internal rehydrating of dentin pulp complex (f) obtaining rehydrated root cement; (g) obtaining rehydrated dental pulp content with a low speed rotation tool; and (h) storing, preservation, processing and/or analyses of the rehydrated dental pulp content and rehydrated root cement, and the use of this method and kits thereof for forensic identification, estimation of post mortem interval (early and late) and determination of possible causes of death.

A fluid-tightly sealable sampling device for analysis of one or more substances in a fluid flow intended to pass through the sampling device is disclosed, wherein it comprises an adsorption device (1) which is hollow and is adapted to be provided with one or more reagents for adsorption of and reaction with said one or more substances in the fluid flow, a filter holder (2), which is hollow and is connected in a fluid-tight way with the adsorption device (1), a filter device (4) adapted to be provided with one or more reagents for adsorption of and reaction with said one or more substances in the fluid flow, a gasket (5) provided with at least one projection (6) engaged with at least one corresponding receiving slot in the filter holder (2), a first external cap (9) detachably connected with the inlet end of the sampling device in a fluid-tight way and a second external cap (13) detachably connected with the outlet end of the sampling device in a fluid-tight way.

A unique fiber core sampler composition, related systems, and techniques for designing, making, and using the same are described. The sampler is used to interface with existing field instrumentation, such as Ion Mobility Spectrometer (IMS) equipment. Desired sampler characteristics include its: stiffness/flexibility; thermal mass and conductivity; specific heat; trace substance collection/release dependability, sensitivity and repeatability; thickness; reusability; durability; stability for thermal cleaning; and the like. In one form the sampler has a glass fiber core with a thickness less than 0.3 millimeter that is coated with a polymer including one or more of: polymeric organofluorine, polyimide, polyamide, PolyBenzlmidazole (PBI), PolyDiMethylSiloxane (PDMS), sulfonated tetrafluoroethylene (PFSA) and Poly(2,6-diphenyl-p-phenylene Oxide) (PPPO). Multiple polymer coatings with the same or different polymer types may be included, core/substrate surface functionalization utilized, and/or the core/substrate may be at partially filled with thermally conductive particles.

A system for opening a secure specimen sample bottle includes a base having a first area and a first raised hollow portion for receiving and holding the specimen sample bottle. The first raised hollow portion has a groove formed along an outer surface thereof. The system includes a cutter for cutting a first portion of the specimen sample bottle. The cutter has a handle at a first end and a second end portion that receives the first portion of the specimen sample bottle and a blade for cutting the first portion. The second end portion has a flange with a raised rail formed along an inner surface of the flange, with the raised rail being received within the groove to couple the cutter to first raised portion during performance of a cutting operation.

This invention relates to an evidence collection and storage apparatus for use in forensic examination and sample collection processes. The apparatus consists of a container and a swab, the swab including a handle portion, shaft portion and a removable head portion, wherein the container includes a cavity adapted to store an object or substance, a lid including a portion of nanomesh and a swab head portion removing means that engages the head portion of the swab within the cavity, enabling the head portion of the swab to be removed or partially removed from the shaft portion of the swab and stored in the container.

Disclosed is a system for screening of traces of illicit substances that may be harmful, such as explosives, radioactive substances, toxics or drugs for example, from very tiny trace concentrations to be detected by way of mass spectrometry being applied to the detached and pre-concentrated particulate matter by the system. Also disclosed is a method in accordance of the system, an arrangement or device as a system element of the system, and a software code on computer readable medium, to control the system and/or acquire data from the system.
