Question: what would happen if you stick protein toxins together?

One aim of my work is to create new nanoscale architecture. A nanometre is one millionth of a millimetre, so this is really quite small. If we can stick together different proteins then we can create structures and objects on this tiny scale just like we can with bricks and houses on the big scale!

The design of smaller and smaller things is great for a lot of areas of science. Electronics is becoming smaller and more powerful and drug delivery needs tiny capsules to target areas of the body. So using proteins to build with is a great way of achieving these designs.
