Active research projects:

Studying the fate and toxicity of nanoparticles using novel biotechnology.

Nanoparticles (NPs) are materials having at least one dimension within the range of 1-100 nm. The commercial and domestic application of manufactured inorganic NPs is increasing exponentially year after year. Because the main concept of nanoparticles is based on size-dependence, it is reasonable to estimate the size-dependent biological effects, e.g. toxicity.
However, there is growing concern that there is a lack of information regarding the environmental fate and consequence of these materials. To enhance the performance of NPs, they are solubilised in a range of buffering agents, and these will further change their environmental fate and behaviour.
In this project by Copper and Silver, nanoparticles will be characterised (colloidal/solution phase of the NPs), and their toxicity (alone and with the range of buffering agents and resultant free ion measured using chemical and biosensor approaches.
