we make money not art
A team, led by Joerg Lahann at the University of Michigan, have won funding to develop a breath test device which will use nanotechnology to detect breast cancer.

A woman would breathe into an over-the-counter device and cancer-indicating metabolites would be attracted into the nanopockets, causing the pored surface to fill and become dense. Then, an electrical charge would be applied so that the straight particles would bend, ejecting the metabolites so that multiple tests could be done in the same device. The metabolites could then be detected through a change in conductance or optically.

I expect a lot of this kind of nano tech will appear in the next few years. Eventually we will breath into a tube in our bathroom every morning and a readout will tell us every harmful bacteria and virus currently in our body…
