Abstract: A population of cells is provided. The population of cells comprising at least two subpopulations of cells, wherein a first subpopulation of the at least two subpopulation of cells includes a first reporter expression construct being expressible in a cell of the first subpopulation when exposed to a first analyte and whereas a second subpopulation of the at least two subpopulation of cells includes a second reporter expression construct being expressible in a cell of the second subpopulation when exposed to a second analyte.

Abstract: A device for detecting a presence of an analyte in a sample. The device comprises a device body configured with at least one reaction chamber configured for containing a sensor capable of producing a detectable signal when exposed to the analyte in the sample. The reaction chambers are in fluid communication with at least one sample port and at least one actuator port via a first set of microfluidic channels arranged such that application of a negative pressure to actuator port delivers fluid placed in the sample port to the reaction chambers.

Abstract: An improved electrode capable of smaller variances and mean breakdown voltage, increased breakdown reliability, smaller electron emission turn-on requirements, and stable electron emissions capable of high current densities include a first electrode material, an adhesion-promoting layer disposed on at least one surface of the first electrode material, and a nanostructure-containing material disposed on at least a portion of the adhesion promoting layer. An improved gas discharge device is provided incorporating an electrode formed as described above. An improved circuit incorporating an improved gas discharge tube device as set forth above is also provided. Further, an improved telecommunications network, incorporating an improved gas discharge tube device as set forth above can also be provided. An improved lighting device is also provided incorporating an electrode constructed as described above.
