Abstract

The magnetic properties of ferromagnetic nanodiscs coated with gold, manufactured using the Dip-Pen Nanolithography method, and were studied by atomic-force and magnetic force microscopy methods. The magnetic discs (dots) are represented as nanoagents (nanorobots) applied in medicine for the cancer cell destruction. The motivation of this work stem from the necessity of the understanding of the magnetization distribution in ferromagnetic discs that is crucial for their application in biomedicine. We have performed the theoretical calculations in order to compare the theoretical image contrast to experimental results. Herein, we report about the fabrication and analysis of biocompatible ferromagnetic nanodiscs with the homogenous magnetized state.
