With the progress of nanotechnology and molecular biology, nanoparticles have been widely studied and applied in biomedicine. Particularly, characterized by unique magnetic property, targeting, and biocompatibility, magnetic nanoparticles have become one of the research hotspots in the nanomedical field. Herein, we summarized the recent advances of magnetic nanoparticles in medicine, including the property, carrier function, MRI, and tumor magnetic inductive hyperthermia of magnetic nanoparticles.

Doxorubicin (DOX) is widely used as a clinical first-line anti-cancer drug. However, its clinical application is severely limited due to the lack of tumor specificity of the drug and severe side effects such as myelosuppression, nephrotoxicity, dose-dependent cardiotoxicity, and multi-drug resistance. To improve the bioavailability of DOX, maximize the therapeutic effect, and reduce its toxicity and side effects, many studies have been done on the nanoformulations of DOX, such as liposomes, polymer micelles, dendrimer, and nanogels. Herein, we review the latest progress of DOX nano-preparations and their anti-tumor effects, hoping to provide theoretical references and new research ideas for the development of new dosage forms of the drug and the technical methods available for clinical application.

FePt nanoparticles have great potential for biomedical applications due to their superior characteristics, including superparamagnetism, resistance to oxidation, and high chemical stability. The present paper reviews the methods used to prepare FePt nanoparticles, surface modifications, and their applications in the biomedical field, such as biosensing, magnetic resonance imaging (MRI), targeted drug delivery, and therapy.

As the third major reason of mortality related to cancer in the world, liver cancer is also the fifth most frequent cancer. Unluckily, a majority of patients succumb and relapse though many progresses have been made in detection and therapy of liver cancer. It has been put forward that in liver cancer, cancer stem cells (CSCs) hold main responsibility for the formation, invasion, metastasis, and recurrence of tumor. Strategies that are intended to target liver CSCs are playing a more and more significant role in supervising the development of liver cancer treatment and assessing new therapeutic methods. Herein, a brief review about molecule markers, signal pathways, separation, and treatment on liver cancer stem cells (LCSCs) is provided in this paper.
