Abstract
The synthesis and characterization of amino-functionalized magnetic nanoparticles (amino-MNPs) were carried out. Amino-MNPs were prepared using polyol technique in an autoclave (121°C) without inert gas. The characterization of particles employed conventional SEM-EDS, TEM, XRD, FTIR, and VSM techniques. Results showed that amount of NaOH affected to the speed of MNP formation. The desirable uniform cubic shape of amino-MNPs was obtained from the addition of 2.50% w/v NaOH for 3 reaction cycles (2 hours/cycle). The amino-MNPs obtained from this condition have cubic shapes with the average size of 43 ± 9 nm. Results from elemental and structure analyses confirmed that the product was pure magnetite. The magnetic properties were ferromagnetism and were very close to a complete superparamagnetism. Fourier transform infrared (FT-IR) spectrum showed that the amino group existed on particle surface. The amino-MNPs of cubic shape were synthesized with facile single step at low temperature, and they have potential to be used for rapid microbial detection and many biological applications.
