“…It was reported that the nanoparticles have the potential for being used as drug delivery systems as well as bioactive fillers for various applications such as wound healing and bone regeneration. Thangaraj et al [180] synthesized superparamagnetic Ce 4 −xSr 1+x Fe 5−x ZnxO 14+δ (x=0-0.45) nanocomposites by the nitrate-citrate sol-gel route for different applications such as drug delivery, sensor, dielectric, conductivity studies, and optical properties. Pathania et al [181] studied the drug release kinetics of chitosan-g-poly(acrylamide)/ Zn (CPA-Zn) nanocomposite synthesized by microwave radiations.…”
