Claim:
1. A sensor array comprising conductive nanoparticles capped with an organic coating in a configuration selected from 1D wires, 2D films, and 3D assemblies, wherein the conductive nanoparticles have a narrow particle size distribution with a mean particle size of 3.5-5 nm, particle sizes in the range of 1-10 nm and a width of the distribution curve at one half of the maximum (FWHM) value being less than or equal to 60% of the mean particle size, and wherein the thickness of the organic coating is in the range of 0.2-4 nm, the sensor array being sensitive to volatile organic compounds at concentrations of less than 1 ppm, wherein the conductive nanoparticles capped with an organic coating are not interlinked through linker molecules.
