They then dipped the gold into a solution containing the protein, allowing it to bind to the treated squares, and dunked the whole lot into a heated (8)__________ of iron salts.
After that, they examined the results with an electron microscope.
Sure enough, groups of magnetite grains had materialised on the treated squares, shepherded into place by the bacterial protein.
In principle, each of these magnetic domains could store the one or the zero of a bit of information, according to how it was polarised.
Getting from there to a real computer memory would be a long road.
For a start, the grains of magnetite are not strong enough magnets to make a useful memory, and the size of each domain is huge by modern computing (9)__________.
But Dr Staniland reckons that, with enough tweaking, both of these objections could be dealt with.
The (10)__________ of this approach is that it might not be so capital-intensive as building a fab.
Growing things does not need as much kit as making them.
If the tweaking could be done, therefore, the result might give the word biotechnology a whole new meaning.
