An Australian invention is making it cheaper, quicker and safer to manufacture the radioactive tracers used in latest medical imaging techniques to track down increasingly smaller clusters of cancer cells.

Like preparing a cake in a mixing bowl, the chemical reactions to make the tracers involve putting the ingredients together in the right proportions. The next generation of tracers can have a more complex recipe—and so can be more difficult to produce using just one ‘mixing bowl’ at a time.
