Abstract

The compositions and methods relate to an organic polymer-inorganic particle sensor material for detecting analytes. Interactions between the polymer and the particles are affected by the presence of analyte, which displaces the polymer and increases its free volume. This change in free volume can be detected, e.g., using an embedded piezoresistive microcantilever (EPM) sensor. Analytes that can be detected include noxious substances, such as hydrogen cyanide gas and carbon monoxide.
