Efficient release and the delivery of active substances are necessary for diverse medical applications including biosensors, biotechnology, and medical therapy. Meanwhile, drug delivery to special tissues or organs has been explored via various modes, especially magneto-responsive targeted drug delivery. Magneto-responsive nanoparticles (NPs), that could be manipulated spatiotemporally through an external magnetic field, have garnered attention as active materials for advanced drug delivery applications. In particular, assorted biocompatible polymeric shells, e.g., carbohydrate polymers, lignin, polyacids, dextran, etc. are often adorned on their surfaces to restrain the cytotoxicity of magnetic NPs in the human body. Thus, a timely overview of bio-catalytic reactions responsive to magnetic fields is beneficial for providing more valuable insights into these efforts. This article aims to review core-shell drug delivery systems based on the significant and most widely exploited magnetic NPs (i.e., Fe3O4 and CoFe2O4), their mechanisms of action, targeting, and controlled drug release aspects. The pivotal requirements and challenges faced in the applications of polymer-coated magnetic NPs for cancer treatment are also briefly discussed.

Magnetic CoFe2O4 nanoparticles doped with metal ions: A review

One of the common bioactive materials used for clinical and biomedical applications is hydroxyapatite (HAp). Bio-waste materials are one of the major natural sources for the preparation of this bio-ceramic powder. Herein, naturally derived nano-HAp was prepared using the ball milling process after annealing of waste pigeon bones at 850 °C followed by cold-pressing the nanoparticles and re-sintering at 850, 950, 1050, and 1150 °C. The ball-milled pigeon-derived nano-hydroxyapatite (PHA) had an average particle size in the range of 50–250 nm and the Ca/P ratio of the sample sintered at 1050 °C was 1.7. Moreover, the hardness and compressive strength of sintered nano-HAp were improved to 47.57 MPa and 3.7 GPa, respectively by increasing the sintering temperature. Furthermore, alkaline phosphatase analysis and MTT assay of PHA indicated significant enhancement in the activity and proliferation of osteoblast cells during the culturing period in comparison to synthetic HAp.
