Special Issue Information

Dear Colleagues,

Magnetic nanomaterials engineered with a large variety of functional coatings have gained much interest because of their possible applications with dual-mode manipulation controlled by a magnetic field and through the appropriate design of surface properties.

Among the magnetic nanomaterials, magnetic iron oxide nanoparticles and their nanocomposites are very promising for innovative applications in nanomedicine and biotechnology, such as nanotherapeutics, multimodal imaging, targeted drug delivery, hyperthermia, analyte monitoring, and enzyme, protein, and nucleic acid separations, due to their large surface area, excellent magnetic properties, and low toxicity. The nature of magnetic nanoparticles’ surface coating is essential for their behavior in biorelevant media. Well separated or in clusters, with proper surface functionalization, usually dispersed in liquid carriers (bioferrofluids) or embedded/encapsulated in polymeric networks, magnetic nanoparticles are the basic building blocks of a large variety of multifunctional vehicles.

The surface modification of magnetic nanomaterials, including the attachment of functional groups necessary for applications based on interactions ranging from nonspecific (e.g., ionic, hydrophobic/hydrophilic, and hydrogen bond) through group-specific to specific-affinity interactions, is an important issue for the future progress of medical and industrial applications.

The design and preparation of functionalized magnetic nanomaterials could have a strong applicative impact in many fields, such as diagnosis and treatment, regenerative medicine, tissue engineering, magnetic bioseparation, protein immobilization, biocatalysis, biosensors, or water purification, to mention only a few.

In this context, the aim of this Special Issue is to publish original research papers and comprehensive reviews dealing with the most important issues concerning the synthesis, advance properties investigations, and potential applications of functionalized magnetic nanomaterials.

Title: Effect of mitoxantrone-coupled SPIONs on pancreatic tumor spheroids
Authors: Ralf Friedrich
Affiliation: Uni-Klinikum Erlangen, Germany
Abstract: Pancreatic ductal adenocarcinoma is a hardly treatable, deadly malignancy. Recently, three-dimensional spheroid cell cultures of pancreatic ductal adenocarcinoma have improved the study of this cancer type. Here we describe the establishment of three-dimensional spheroid cell structures in different human pancreatic ductal adenocarcinoma cell lines and a potential new treatment approach using superparamagnetic iron oxide nanoparticles (SPION) as a drug delivery system for mitoxantrone (MTO). Following the generation of different tumor spheroids, free MTO and MTO-functionalized SPIONs were tested for cytotoxic efficacy. The tumor spheroids showed a dose-dependent toxic effect to the treatment with only slightly altered differences between free MTO and SPION-MTO, indicating the applicability of the functionalized SPIONs for magnetic drug targeting.
