Figure 3.

Time course of uptake of L-[¹⁴C]glutamate by control synaptosomes (solid line); synaptosomes in presence of uncoated γ-Fe₂O₃ nanoparticles (dashed line) and D-mannose-coated γ-Fe₂O₃ nanoparticles (dotted line). Uptake was initiated by the addition of L-[¹⁴C]glutamate to synaptosomes, after incubation the samples were rapidly sedimented and radioactivity was determined as described in section Experimental. Data represent mean ± SEM of three independent experiments.
