(a) X-ray diffraction patterns with calculated mean size of crystal for magnetite nanoparticles obtained by microwave (MW) and thermal decomposition (TD) using different solvents; (b) zeta potential measurements as a function of pH for DMSA coated nanoparticles and uncoated magnetite for comparison; (c) hydrodynamic size in number distribution; (d) infrared spectra for DMSA coated nanoparticles and DMSA for comparison. Inset shows the IR low frequency range.
