1. A flow-through aerosol capture device comprising:
a chamber defining an airflow path, and
a heat-stable aerogel filter, disposed in the airflow path for capturing aerosol particles when an aerosol-containing gas passes through the filter;
wherein the heat-stable aerogel filter comprises a heat-stable polyacrylonitrile PAN) aerogel, a heat-stable PAN/silica aerogel, a heat-stable polyetherimide aerogel, or a heat-stable polyamide aerogel.
