Magnetic Nanoparticle Systems for Nanomedicine—A Materials Science Perspective

Iron oxide nanoparticles are the basic components of the most promising magneto-responsive systems for nanomedicine, ranging from drug delivery and imaging to hyperthermia cancer treatment, as well as to rapid point-of-care diagnostic systems with magnetic nanoparticles. Advanced synthesis procedures of single- and multi-core iron-oxide nanoparticles with high magnetic moment and well-defined size and shape, being designed to simultaneously fulfill multiple biomedical functionalities, have been thoroughly evaluated. The review summarizes recent results in manufacturing novel magnetic nanoparticle systems, as well as the use of proper characterization methods that are relevant to the magneto-responsive nature, size range, surface chemistry, structuring behavior, and exploitation conditions of magnetic nanosystems. These refer to particle size, size distribution and aggregation characteristics, zeta potential/surface charge, surface coating, functionalization and catalytic activity, morphology (shape, surface area, surface topology, crystallinity), solubility and stability (e.g., solubility in biological fluids, stability on storage), as well as to DC and AC magnetic properties, particle agglomerates formation, and flow behavior under applied magnetic field (magnetorheology).

“…The physical processes that are used to measure a certain system are often convenient to be considered in a reciprocal space. The intensity of small-angle scattering is known to be proportional to the Fourier transform of the correlation function [3,4]. From whence, it follows that the scattering intensity (the differential scattering cross-section per unit volume) for bulk fractal systems with the dimension looks like…”

The concept of fractals is widely used in various fields of science. By an example of the results obtained by L.A. Bulavin’s scientific school, the tendency toward a more intense application of the fractal analysis to structural studies of nanosystems has been demonstrated. It is shown that the peculiarities in the distribution of nanosystems over their fractal dimensions are related to the mechanisms of growth and aggregation of the dispersed phase. An important aspect of the considered issue is the kinetics of the process under the influence of various factors. The leading role of small-angle scattering methods (analysis in the reciprocal Fourier space) together with microscopy ones (analysis in the direct space) used to study advanced nanostructured materials in various states of matter is emphasized.
