Issue Date: | 2020 | Publisher: | MDPI | Source: | Nanomaterials, 10 (12) (Art N° 2486) | Abstract: | Encapsulated magnetic nanoparticles are of increasing interest for biomedical applications. However, up to now, it is still not possible to characterize their localized magnetic properties within the capsules. Magnetic Force Microscopy (MFM) has proved to be a suitable technique to image magnetic nanoparticles at ambient conditions revealing information about the spatial distribution and the magnetic properties of the nanoparticles simultaneously. However, MFM measurements on magnetic nanoparticles lead to falsifications of the magnetic MFM signal due to the topographic crosstalk. The origin of the topographic crosstalk in MFM has been proven to be capacitive coupling effects due to distance change between the substrate and tip measuring above the nanoparticle. In this paper, we present data fusion of the topography measurements of Atomic Force Microscopy (AFM) and the phase image of MFM measurements in combination with the theory of capacitive coupling in order to eliminate the topographic crosstalk in the phase image. This method offers a novel approach for the magnetic visualization of encapsulated magnetic nanoparticles. | Notes: | Mobius, H (corresponding author), Univ Appl Sci Kaiserslautern, Dept Comp Sci Micro Syst Technol, Amerika Str 1, D-66482 Zweibrucken, Germany. marc.fuhrmann@hs-kl.de; anna.musyanovych@imm.fraunhofer.de; ronald.thoelen@uhasselt.be; Sibylle.von.Bomhard@imm.fraunhofer.de; hildegard.moebius@hs-kl.de |
