    Abstract: An apparatus comprises a housing defining a chamber that has a liquid disposed therein, and a sensor submerged in the liquid. The sensor comprises a porous conductive film on a substrate, and the film comprises chemiresistive semiconducting metal oxide structures. The sensor also comprises an electrode pair operably connected to the porous conductive film for generating electric current in the film and for detecting a change in an electrical property of the film. The apparatus can be used to detect, identify, and quantify ions and molecules in a liquid sample. Molecules and ions, in a liquid sample, that interact with the porous conductive film can cause a change in an electrical property of the film. The change in electrical property of the film can be correlated with the presence and amount of the molecules or ions.

    Abstract: An array of sensor devices, each sensor including a set of semiconducting nanotraces having a width less than about 100 nm is provided. Method for fabricating the arrays is disclosed, providing a top-down approach for large arrays with multiple copies of the detection device in a single processing step. Nanodimensional sensing elements with precise dimensions and spacing to avoid the influence of electrodes are provided. The arrays may be used for multiplex detection of chemical and biomolecular species. The regular arrays may be combined with parallel synthesis of anchor probe libraries to provide a multiplex diagnostic device. Applications for gas phase sensing, chemical sensing and solution phase biomolecular sensing are disclosed.
