Monoliths doped with azurin were prepared adding the protein to the buffer solution to be mixed with the sol .
This concept does not entail the simultaneous existence of a silica gel and a sol , but rather a coexistence of short-chain silica polymers and monosilicic acid that condense to form quartz fibers.
At this stage the mixture is known as a sol , and contains sufficient energy for the molecules to move freely in the mixture.

Garcia merely printed more of them, so many that a new currency, the nuevo sol , had to be invented to erase the memory of the old one.
