Abstract

The World Health Organisation estimates that 7 million people die prematurely from air pollution each year, with more than half of these linked to indoor air pollution sources. One of the largest challenges facing the fight against air pollution is detecting the level and size of particulates in the environment. As the most harmful of these particulates are on the micro to nanometre scale, and therefore aren’t visible to the naked eye. In this seminar, I present a novel method for particulate detection.

Using a process called dielectrowetting, it is possible to spread a droplet of a known, non-conductive substance into a thin liquid film at the push of a button. This liquid film can capture particulates directly out of the air, e.g. soot particulates from a candle, a common source of indoor air pollution. By analysing the film it is then possible to determine the sizes of the captured particulates and begin to understand the threat that simple everyday items can pose.

This seminar is hosted by Andrew Edwards & Ian Shuttleworth
