In vitro J774A cell viability tests in the presence of FePt nanoparticles. A) Cell viability as a function of FePt nanoparticle concentration after 1 and 24 h of incubation in the presence of the particles. B) Optical fluorescent images of the J774A cell samples from the control, 250 and 500 pgmL-1 showing inhibited cell division in the higher concentration sample after 24 h. The green and red colors indicate live and dead cells. Scale bar is 100 μm.
