(ANSA) - Rome, October 16 - Italian scientists have
discovered a new kind of 'magnetic' bacteria that could be used
to transport medicinal drugs directly into ailing cells.
Researchers at the National Institute of Geophysics and
Vulcanology have identified a chain of pure magnetite crystals
in the bacteria 'Magnetobrivio blakemorei', discovered by a
group of US reserachers near the mouth of the river Neponset in
Massachusetts.
Each crystal measures between 20 and 50 nanometres, over 10
times the diameter of the double helix in DNA.
'Magnetobrivio blakemorei' belongs to the group of
magnetotactic bacteria discovered by US scientist Richard
Blakemore in 1975 containing crystals that are sensitive to the
earth's magnetic field.
This internal 'compass' could have important applications
in several fields including medicine for the transportation of
pharmaceuticals directly into diseased cells.
