Abstract

A biocompatible nanocomposite aerogel is provided that is relatively non- conductive in its dry form, but rendered conductive when wetted or moistened, making it suitable for use in a variety of sensors, including vapor sensors. The high porosity of the nanocomposite aerogel also renders it a good adsorbent for purposes such as environmental remediation of pollutants.
