ABSTRACT |
Recently, a variety of nanoparticles have been considered as an attractive way that is effective and helpful in diagnosis and treatment
of cancer and diseases through development in nanoscience and nanotechnology. Nanoparticles refer to tiny particles between 100 nm
and 1 μm. The objective of this paper is to review the current applications, the research trend, and the possibility in future of the
metallic nanoparticles in drug delivery, imaging, therapy, and combined imaging and therapy, as well as hearing research. The
nanoparticles for effective drug delivery have been used to selectively target and kill the cancer cells or tumor cells and to transport
molecules, nanoparticles, and cells into solid tumors in chemotherapy and radiation. The nanoparticles in hearing research have been
used to prevent or treat the noise-, ototoxicity-, inflammatory-, viral-, and immune-mediated hearing loss and cell death processes
using genetic and trophic factors enhancing repair processes of hair cell in the cochlea. The nanoparticles for effective imaging have
been used to confirm a detailed view of targeting in live cells and their interactions with intracellular molecules and as contrast agents
for CT, MRI, and x-ray imaging. The nanoparticles in therapy have been used in chemotherapy, immunotherapy, radiotherapy,
thermotherapy, and photodynamic therapy by targeting the fast growing cells, blocking some critical elements of the cell division
process, transporting various compositions, and increasing the dose and effectiveness of x-rays. Recently, the nanoparticles have been
used to increase the effectiveness of individual modality image or therapy by combining noninvasive multimodality imaging and
molecular therapy. This method can provide a new insight and intuition on the diagnosis and treatment of the various cancers and
diseases including hearing loss. |
