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.

Abstract: An apparatus for installing multiple utility meters is provided. The apparatus may be attachable to an existing setter in place of a utility meter. The apparatus includes connectors for a plurality of utility meters, wherein one of the utility meters attaches such that intake into the meter and outtake out of the meter utilize the setter. The apparatus may include connectors for one or more additional meters and secondary outtakes for each of the additional meters.
