Cancer is an abnormal cell growth which tends to proliferate in an uncontrolled way and, in some cases, leads to metastasis. If cancer is left untreated, it can immediately cause death. The use of magnetic nanoparticles (MNPs) as a drug delivery system will enable drugs to target tissues and cell types precisely. This study describes usual strategies and consideration for the synthesis of MNPs and incorporates payload drug on MNPs. They have advantages such as visual targeting and delivering which will be discussed in this review. In addition, we considered body magnetic field to make drug delivery process more effective and safer by the application of MNPs and tumor-on-chip.

Hearing loss is one of the most common disabilities affecting both children and adults worldwide. However, traditional treatment of hearing loss has some limitations, particularly in terms of drug delivery system as well as diagnosis of ear imaging. The blood–labyrinth barrier (BLB), the barrier between the vasculature and fluids of the inner ear, restricts entry of most blood-borne compounds into inner ear tissues. Nanoparticles (NPs) have been demonstrated to have high biocompatibility, good degradation, and simple synthesis in the process of diagnosis and treatment, which are promising for medical applications in hearing loss. Although previous studies have shown that NPs have promising applications in the field of inner ear diseases, there is still a gap between biological research and clinical application. In this paper, we aim to summarize developments and challenges of NPs in diagnostics and treatment of hearing loss in recent years. This review may be useful to raise otology researchers’ awareness of effect of NPs on hearing diagnosis and treatment.

Liver cancer has a high incidence and a poor prognosis, which seriously affects human health. Doxorubicin is one of the chemotherapeutics used in the treatment of tumours, but its severe adverse reactions, especially cardiac toxicity, have limited its clinical application. The nanometre drug delivery system enables drug-loaded nanoparticles to be specifically concentrated in tumour tissues, increasing cell uptake and improving curative effect. Therefore, in this paper, folic acid-modified mesoporous silica nanoparticles (MSN-NH2-PEG-FA) were synthesized by modifying the folic acid on the surface of a drug carrier by using the characteristics of the expression of folic acid receptors, and using it as a drug. The carrier was loaded with antitumor drug doxorubicin hydrochloride (DOX), and a nanometre drug delivery system (MSN-NH2-PEG-FA/DOX) was constructed. At the same time, the near-infrared dye Cy5 was used to mark the mother nucleus to construct fluorescent nanoparticles (MSN-NH2-PEG-FA/DOX-Cy5) for cell and tumour imaging, so as to obtain the abdominal image of liver cancer patients, thereby realizing diagnosis and treatment. The research results show that the carrier can specifically gather in the liver area, reduce the distribution in the heart, reduce the toxic and side effects of drugs, and prolong the survival time of patients. The results of this study provide new ideas for the treatment of liver cancer, and provide a new theoretical basis and experimental basis for the study of inorganic nanomaterials as targeted drug delivery systems.
