摘要： A sensor (200) to detect solid particles of a target salt can include a support substrate (210), an adsorption layer (240), a sensing layer (230) oriented between the support substrate (210) and the adsorption layer (240), and an electrode pair (220) in contact with the sensing layer (230) and separated by the sensing layer (230). The adsorption layer (240) can include an ion exchange medium formed of a first porous structured material functionalized with basic or acidic functional groups. The basic or acidic functional groups can remove an acid or base component from the target salt to form a free base or free acid, respectively, of the target salt. The sensing layer (230) can include a second porous structured material functionalized to detect the free base or acid of the target salt by a change in conductivity.

摘要： A chemiresi stive vapor sensor compound for detecting target vapors can comprise a perylene-tetracarboxylic diimide (PTCDI) core according to structure (I), where R can be a morphology control group or -A'-D', A and A' can be independently a linking group, D and D' can be independently a strong electron donor which transfers electrons to the PTCDI core sufficient to form an anionic PTCDI radical of the PTCDI core, and Rl to R8 can be independently a side group. A chemiresi stive vapor sensor (100) for detection of a target compound can comprise an assembly of nanofibers (105) formed of the chemiresi stive sensor compound and a pair of electrodes (150A, 150B) operatively oriented about the assembly of nanofibers (105) to allow electrical current to pass from a first electrode in the pair of electrodes (150A, 150B) through the assembly of nanofibers (105) and to a second electrode in the pair of electrodes.
