“…In recent years, nanomagnetic particles have generated a lot of interest in the biomedical applications like MRI contrast enhancement, magnetic separation, targeted delivery and hyperthermia [1][2][3]. Among the different magnetic oxides, Fe 3 O 4 and g-Fe 2 O 3 particles have been extensively studied as they are known to be biocompatible within certain threshold limits.…”

MnO2 nanoparticles have been synthesized by a simple combustion method using MnSO4.4H2O. The crystalline phase, morphology, optical property and magnetic property of the as prepared nanoparticle were characterized using XRD, FT-IR, FTRaman, SEM, UV-Vis, PL and VSM respectively. Structural studies by XRD indicate that the synthesized material as tetragonal rutile crystal structure. FT-IR and FT-Raman analysis revealed the stretching vibrations of metal ions in tetrahedral co-ordination confirming the crystal structure. The PL and UV analysis having an emission band at 390 nm, showed a prominent blue peak at 453 nm as well as a green emission lines at 553 nm with band gap energy of 3.2eV. Magnetic measurements indicate that the Néel temperature of the β-MnO2 structures is 92.5K for Hc = 100 Oe which showed antiferromagnetic behaviour.

A well designed controlled drug delivery system can provide a therapeutic amount of drug to the proper site in the body and then maintain the desired drug concentration for the specific period of time.A number of approaches are available in delivering therapeutic substance to the target site in sustained and controlled release fashion.One such approach is using magnetic microspheres as carriers for drugs. Microsphere drug delivery system has gained vast attention due to its diverse applications that range from targeting the drug to specific site to imaging and helping the diagnostic features. One of its important application is that it is used for targeting tumors using anticancer drugs. Being more stable, it has an advantage over other delivery systems like liposomes. The main objectives of this review is to highlight some important aspects of magnetic microspheres as a novel drug delivery system. The review shall cover definitions, concepts, types, mechanism of targeting, evaluation and characteristics of magnetic microspheres as well as various methods and techniques used in their preparations. The review also entails various applications and future prospects of magnetic microspheres.
