Chemistry and Fashion: Tools for a Cleaner Environment

Of late, Professor Anthony Ryan OBE's work has focused on polymers and nanotechnologies able to combat air pollution. In 2014, Professor Ryan along with Professor Simon Armitage prepared a 10 meter by 20 meter size poster coated with microscopic, pollution eating nanoparticles of titanium dioxide. Placed on a building, this giant poster can absorb the toxic emission from around 20 cars each day. Reacting to light and oxygen, the nanoparticles eat up nitrogen oxides, which you can't see or feel but which have been linked to breathing problems including asthma.

Together with the fashion designer Helen Storey he is developing a laundry additive called Catclo that sticks to the surface fibres of clothes and reacts with airborne nitrogen oxides to neutralise them.
