    Abstract: A print head comprising nested chambers for in-situ reactant formation is disclosed. The print head comprises a first chamber nested within a second chamber. The first chamber comprises a first nozzle, the second chamber comprises a second nozzle. The first nozzle is substantially coaxial with the second nozzle. A susceptor to convert electromagnetic energy to heat is within the first chamber. The susceptor comprises one or more openings extending between the upper portion and the lower portion. The susceptor may be heated by induction heating or by optical heating to vaporize a precursor substance within the first chamber. The vapor may react with a reactive gas flowing through the first chamber or expand through a nozzle into a second chamber where the vapor may react with the reactive gas, forming nanoparticles. Patterned films may be written onto a two-dimensional or three-dimensional surfaces.

    Abstract: Disclosed herein are embodiments of sensor devices comprising a sensing component able to determine the presence of, detect, and/or quantify detectable species in a variety of environments and applications. The sensing components disclosed herein can comprise MOF materials, plasmonic nanomaterials, or combinations thereof. In an exemplary embodiment, light guides can be coupled with the sensing components described herein to provide sensor devices capable of increased NIR detection sensitivity in determining the presence of detectable species, such as gases and volatile organic compounds. In another exemplary embodiment, optical properties of the plasmonic nanomaterials combined with MOF materials can be monitored directly to detect analyte species through their impact on external conditions surrounding the particle or as a result of charge transfer to and from the plasmonic material as a result of interactions with the plasmonic material and/or the MOF material.
