Sensors based on nanosstructured composite films
First Claim
1. A composite article with an electrically conductive surface, comprising an encapsulating layer having a regular or random array of discrete microstructures, each microstructure comprising an organic compound wherein the molecule thereof is planar and comprises claims or rings over which π
- -electron density is extensively delocalized and an optional conformal coating enveloping said whisker-like structure, wherein said array of discrete microstructures is encapsulated in said encapsulating layer, such that one end of each microstructure is embedded within said encapsulating layer and the other end of each microstructure is exposed and coincident with the surface of said encapsulating layer.

Abstract
An electrically reactive composite article comprising a random or regular array of microstructures partially encapsulated within an encapsulating layer, microstructures each comprising a whisker-like structure, optionally having a conformal coating enveloping the whisker-like structure is described. The composite article is useful as an electrically conducting component of a circuit, antenna, microelectrode, reactive heater, and multimode sensor to detect the presence of vapors, gases, or liquid analystes.
