Elegant pH-Responsive Nanovehicle for Drug Delivery Based on Triazine Dendrimer Modified Magnetic Nanoparticles.

Owing to properties of magnetic nanoparticles and elegant three-dimensional macromolecule architectural features, dendrimeric structures have been investigated as nanoscale drug delivery systems. In this work, a novel magnetic nanocarrier, generation two (G2) triazine dendrimer modified FeO@SiO magnetic nanoparticles (MNP-G2), was designed, fabricated, and characterized by Fourier transform infrared (FT-IR), thermal gravimetric analysis (TGA), vibrating sample magnetometer (VSM), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), and dynamic light scattering (DLS). The prepared MNP-G2 nanosystem offers a new formulation that combines the unique properties of MNPs and triazine dendrimer as a biocompatible material for biomedical applications.
