摘要： A process is disclosed for using microsensors elements embedded in or on articles for detecting target chemical and/or target environmental conditions of interest, including materials hazardous to human health and/or associated with illegal activity. The microsensor elements can be fabricated on a single semiconductor chip, and can be made indetectable to facilitate secure surveillance of potentially illegal activities.

摘要： A sensor includes a substrate, a first electrode, a second electrode spaced from the first electrode, and a sensing medium on the substrate between the first electrode and the second electrode. The sensor medium includes a functionalized graphitic material and an uncondensed graphitic carbon nitride disposed upon the functionalized graphitic material. The sensor further includes a system for applying electromagnetic energy to the sensing medium to increase the conductance of the sensing medium, and circuitry including at least one measurement system in operative connection with the sensor to measure a variable relatable to the conductance of the sensing medium which is dependent upon the presence of an analyte to be detected.

摘要： A thin film gas sensor device includes a substrate, a nanostructured thin film layer, and a first and a second electrode. The nanostructured thin film layer is supported by the substrate and is formed with a semi-conductor material including holes. The semiconductor material is configured to undergo an increase in a density of the holes in the presence of a target gas, thereby decreasing an electrical resistance of the nanostructured thin film layer. The first and the second electrodes are supported by the substrate and are operably connected to the nanostructured thin film layer, such that the decrease in electrical resistance can be detected.

摘要： The present invention relates to the detection of microbial organisms using non-toxic nanostructured sensors that change their physical or chemical properties upon detecting these microbial organisms. These sensors allow an unskilled person to rapidly detect the presence of microbial contamination.

摘要： A nanoscale protein-sensing platform with a non-equilibrium on-off switch that employs dielectrophoretic and hydrodynamic shear forces to overcome these thermodynamic limitations with irreversible kinetics. The detection sensitivity is achieved with complete association of the antibody-antigen-antibody (Ab-Ag-Ab) complex by precisely and rapidly assembling carbon nanotubes (CNT) across two parallel electrodes via sequential DC electrophoresis and dielectrophoresis (DEP), and with single-CNT electron tunneling conductance. The high selectivity is achieved with a critical hydrodynamic shear rate between the activated dissociation shear rates of target and non-target linkers of the aligned CNTs.

摘要： One example includes a sensor for sensing NOx, including an electrically insulating substrate, a first electrode and a second electrode, each disposed onto the substrate, wherein each of the first electrode and the second electrode has a first end configured to receive a current and a second end and a sensor element formed of nickel oxide powder, the sensor element disposed on the substrate in electrical communication with the second ends of the first electrode and the second electrode. In some examples, electronics are used to measure the change in electrical resistance of a sensor in association with NOx concentration near the sensor. In some examples, the sensor is maintained at 575° C.
