Preparation, toxicity reduction and radiation therapy application of gold nanorods

J Nanobiotechnology. 2021 Dec 28;19(1):454. doi: 10.1186/s12951-021-01209-4.

Abstract

Gold nanorods (GNRs) have a broad application prospect in biomedical fields because of their unique properties and controllable surface modification. The element aurum (Au) with high atomic number (high-Z) render GNRs ideal radiosensitive materials for radiation therapy and computed tomography (CT) imaging. Besides, GNRs have the capability of efficiently converting light energy to heat in the near-infrared (NIR) region for photothermal therapy. Although there are more and more researches on GNRs for radiation therapy, how to improve their biocompatibility and how to efficiently utilize them for radiation therapy should be further studied. This review will focuse on the research progress regarding the preparation and toxicity reduction of GNRs, as well as GNRs-mediated radiation therapy.

Keywords: Gold nanorods (GNRs); Preparation; Radiation sensitization; Radiation therapy; Toxicity reduction.
