Just add water


On-demand pharmaceutical manufacturing

US researchers have been working on a molecular manufacturing method that can produce a broad range of biomolecules anywhere in the world, without power or refrigeration. The result is a ‘just add water’ solution that affordably, rapidly and precisely generates compounds that could be administered as therapies or used in experiments and diagnostics.


The new method employs two types of freeze-dried pellets containing different kinds of components. The first kind of pellet contains the cell-free ‘machinery’ that will synthesise the he ability to synthesise and
