Carbon-coated Nanomagnets for Cancer Treatment

German scientists in experiments on mice have demonstrated the effectiveness of a new approach to the destruction of tumors by heating to a high temperature. The use of iron for the manufacture of nanoparticles allows them to be heated to higher temperatures than traditional iron oxide nanoparticles are heated, and the carbon coating prevents metal oxidation, potentially reducing the effectiveness of therapy.

The authors tested the biocompatibility of the new nanoparticles by incubation with human cells: a line of PC-3 prostate cells and a line of fibroblasts. The presence of nanomagnets in culture had no significant negative effects on the vital activity of cells and did not change the ratio of cells in different phases of the cell cycle and the level of apoptosis.

This development is a promising approach to the treatment of many types of cancer without damaging healthy body tissues characteristic of chemotherapy and surgical interventions.

Published by Taylor A. et al. Carbon-coated nanomagnets as potential hyperthermia agents was included in the collection of the 103rd Annual Scientific Congress of the American Urological Association.
