Targeting G Protein‐Coupled Receptors with Magnetic …

Iron‐filled carbon nanotubes (CNTs) are an optimal platform for theranostic purposes, and the use of a magnetic field can be exploited for cancer magnetic cell sorting and thermal therapy. In this work, we have conjugated an A 3 AR ligand on the surface of iron‐filled CNTs with the aim of targeting cells overexpressing A 3 ARs.

Magnetic carbon nanotubes: synthesis by a simple ...

In this study, a new synthesis technique of magnetic multiwall carbon nanotubes (MMWCNTs) was achieved and its application for drug-loading ability was assessed. MMWCNTs were prepared by a simple solvothermal process, which can easily alter the size (100–350 nm), location, and denseness of Fe3O4 beads fixed on MWCNTs as well as the MWCNTs structure via controlling the reaction parameters.
