Interactions between magnetic nanowires and living cells: uptake, toxicity, and degradation.


We report on the uptake, toxicity, and degradation of magnetic nanowires by NIH/3T3 mouse fibroblasts. Magnetic nanowires of diameters 200 nm and lengths between 1 and 40 μm are fabricated by controlled assembly of iron oxide (γ-Fe(2)O(3)) nanoparticles. Using optical and electron microscopy, we show that after 24 h incubation the wires are internalized by… (More)
