The door to a new class of materials has been opened through the combination of aerogels and semiconductor nanocrystals. Semiconductor nanoparticles are used as building blocks to give dry, mesoporous aerogels with large internal surface areas (see picture, center: wet CdS gel; left: unwashed CdS aerogel; right: monolithic CdS aerogel; scale in mm). These materials have many potential uses including in photovoltaic devices and sensors.
