Comments on Bacteria Guided Through Bloodstream W/Magnetic Fields
Rather than building nanomachines (or building a shrink ray!), how about using actual bacteria as the 'robots' to move material through the bloodstream to a desired spot. (Read
the complete story)
| "Here are a few more details for Strain MC-1:
"Strain MC-1 is a magnetotactic bacterium that was originally isolated from the Pettaquamscutt Estuary (Rhode Island, USA; Meldrum et al., 1993) and represents the only magnetotactic coccus in pure culture... Cells are 1-2 microns in diameter and motile having two bundles of flagella located on one side of the cell, a flagellar pattern referred to as bilophotrichous. Each cell usually contains a single chain of membrane-bounded magnetite crystals (magnetosomes). Like other magnetotactic bacteria (e.g., Magnetospirillum magnetotacticum), MC-1 cells use the chain of magnets as a compass to find favorable environmental conditions, the oxic-anoxic interface, by swimming along the Earth’s geomagnetic field lines. However, unlike cells of M. magnetotacticum which swim in both directions under oxic conditions, cells of MC-1 display a polar preference. It has been shown that magnetotaxis works in conjunction with aerotaxis (Frankel et al., 1997). Cells of M. magnetotacticum appear to use the Earth’s magnetic field lines as an axis for alignment and to rely on a temporal sensory mechanism of aerotaxis to find and maintain an optimal position in oxygen gradients; this is referred to as axial magneto-aerotaxis. Cells of MC-1 use the magnetic field directionally and appear to have a novel aerotactic sensory mechanism that seems to function as a two-way switch; this is referred to as polar magneto-aerotaxis. Cells of MC-1 also exhibit a response to short-wavelength light (< 500 nm) which causes them to swim persistently parallel to the magnetic field during illumination." (From Magnetococcus sp. MC-1)" (Bill Christensen 5/3/2009 9:58:04 PM) |
