This field is moving fast so the nature of the projects are also moving on so I'll just give an overview of the sorts of things we are doing at the moment.

We have recently shown that for nanobubbles to survive for significant periods of time they need to be coated with a layer of material. We call these 'armoured' nanobubbles. We are now interested in what properties the armour must have to be effective and we wish to explore;

• How we might control the stability of nanobubbles by altering the armour. For example can we destroy them at will?
• How we might confer different properties on nanobubbles by changing the properties of the armour?
• How we can control the size of nanobubbles? This is particularly important in medical imaging applications.
• How we can use nanobubbles to make nanoparticles?

Nil courses. A curious mind. Logical and creative thinking, persistence and imagination and some grit and determination
