Abstract:
A composition comprising a diatom frustule and a metal coating, and a method for making the same, are disclosed herein. The metal coating may comprise a metal film or metal nanoparticles, which may be attached to the surface via a linker. The composition has a surface coverage ratio of from about 1% to about 100%. The composition may also comprise an antibody. Also disclosed is a method for using the composition comprising contacting the composition with a target molecule, exposing the composition to light, and measuring the resulting Raman scattering.
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, redox-active molecules, a metal, or any combinations thereof. In some exemplary embodiments, optical properties of the plasmonic nanomaterials and/or the redox-active molecules combined with MOF materials can be monitored directly to detect analyte species through their impact on external conditions surrounding the material or as a result of charge transfer to and from the plasmonic nanomaterial and/or the redox-active molecule as a result of interactions with the MOF material.

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.
Abstract:
Techniques and solutions are provides for increasing data bandwidth to wireless devices in a wireless network. Data bandwidth to a wireless device can be increased by using an array of wireless transmitters of one type, arranged to cover one or more areas of an enclosed space, in combination with one or more wireless transmitters of another type, to simultaneously transmit data to the wireless device over different wireless communication channels.
