Scientists in the US have immobilised photocatalytic titania nanoparticles onto cellulose fibres to improve their ability to remove harmful bacteria (in this case cyanobacteria toxin microcystin-LR) from drinking water.
The team found that the type of titania nanoparticle (visible light activated or UV light activated), the surface area of the fibre mat and loading solution pH all had an effect on the distribution of titania along the fibres. Read the article for free until 19th June.
