Regeneration from single cells

Finally, SECM studies on single HeLa cells have also focused on their interaction with silver nanoparticles. The detection scheme relied on the interaction of an iridium hexachloride couple with silver nanoparticles. When the microelectrode approached the HeLa cells, two mechanisms competed with IrCV regeneration from IrClg by the silver nanoparticles adsorbed on the ceU surface IrCl " diffusing across the intracellular space and IrCI transported in the intracellular lumen where it could subsequently be reduced by an intracellular redox species or silver nanoparticles segregated in the nucleus (Eigure 12.23).
