Abstract: Systems and methods are provided for measuring analytes (e.g., greenhouse gases) in the air over a field in an agricultural setting. The existing equipment of a center pivot and an attached arm can be used by adding reflectors and/or point sensors on the arm and an analyzer unit on the center pivot. The analyte concentration in the air can be detected down to a sensitivity of 1 part per billion or less.

Abstract: Systems and methods are provided for measuring analytes in the air over an area. Open-path sensing equipment can be used to measure the concentration of one or more analytes over the area. The open-path sensing equipment can include at least one light source configured to provide light at a respective predetermined wavelength, a detector, and a plurality of mirrors. The open-path sensing equipment can further include and/or be operated with electronics, such as field programmable gate array (FPGA) electronics.

Abstract: Products, such as a watch, an item of jewelry, a pair of eyeglasses or sunglasses, or the like, may be configured to be authenticated and/or tracked by way of producing a light emission having one or more predetermined characteristics. More particularly, a product may comprise a metal component, at least a portion of which contains wave-shifting marker crystals configured to emit light having one or more characteristics by which the product may be identified. Also described are packages, such as for cosmetics or fragrances, containing wave-shifting crystals that, when excited, emit light having one or more characteristics by which information about the package, such as a unique package identifier, may be obtained.

Abstract: The present disclosure is directed to pharmaceutical packages, such as syringes, vials, etc., containing wave-shifting crystals that, when excited, emit light having one or more characteristics by which information about the package, such as a unique package identifier, may be obtained. The wave-shifting crystals may be rare earth doped crystals. In some embodiments, the wave-shifting crystals may be incorporated into or onto a wall of a vessel, e.g. a syringe barrel or vial, in a way that maintains transparency of the vessel wall. In other embodiments, the wave-shifting crystals may be incorporated into or onto a portion of the package that need not be transparent, such as a needle shield, tip cap, or vial closure. The wave-shifting crystals may be used to track and/or authenticate a pharmaceutical package.

Abstract: Disclosed is a spectroscopic device, system, and method for measuring the concentration of one or more molecular species of interest in a gas, liquid or solid sample, where the device may be portable, may be commercially manufactured, and/or may be adapted to existing systems and/or integrated with new systems to provide optical gas sensing for such systems. The disclosed devices, systems, and methods can be particularly useful in monitoring the purity of, e.g., a certain gas species, including determining whether a gas mixture contains certain gas species above a set concentration limit.

Abstract: The subject invention provides methods and assays for multiplexed detection of analytes using nanocrystals that are uniform in morphology, size, and composition based on their unique optical characteristics. The described methods and assays are particularly useful for detection of microbes and/or microbe-based agents in a complex environmental sample.
