Figure 3From: One-Pot Green Synthesis and Bioapplication ofl-Arginine-Capped Superparamagnetic Fe3O4 NanoparticlesMagnetic hysteresis loop measured at room temperature for thel-arginine-capped Fe3O4 nanoparticles. The NPs show superparamagnetic properties at room temperature, and the Ms is about 49.9 emu g−1Back to article page
