Comparison of citric acid vs. ascorbic acid functionalized magnetic nanoparticles
Kaitlyn Jo Kotlarz
Magnetic nanoparticles (MNPs) have attracted broad attention due to their potential biomedical applications, such as drug delivery and bio-imaging, as well as other applications involving materials separations and harvesting energy. Citric acid is a widely accepted coating material for MNPs; however, very few studies have focused on ascorbic acid coated MNPs. Here, citric acid and ascorbic acid coated iron oxide nanoparticles were synthesized to study the size distribution and stability. The nanoparticles were characterized by multiple techniques including dynamic light scattering, atomic force microscopy, and Fourier transform infrared spectroscopy. It was found that citric acid coated MNPs were more stable than ascorbic acid, but ascorbic acid could be a possible alternative coating material.
