Drug Loading and Release for Specific Diseases

Biomedical applications of solid silica-coated magnetite nanoparticles are not highly reported in literature. Conventional biomedical uses are almost restricted to diagnostic issues. Other magnetic-silica materials such as mesoporous were last explored as target drug delivery.
Among the scarce literature reports, the existent are devoted to the use of solid silica coated magnetic nanoparticles as target drug delivery in the treatment of oncological diseases and in gene delivery and transfection. The use of these kinds of nanosystems as theranostics was also reported in the last few years. In this sense, the possibility is being explored to design a nanocarrier to be useful in more than one diagnostic technique, leading to multiple theranostics tools. In most cases, hard work on the design is required in order to assess selectivity and specificity in their function. To these ends silica coated magnetic nanoparticles are commonly modified with suitable ligands able to interact with biomarkers associated with the disease to treat.
