Abstract

Surface functionalized magnetic iron oxide nanoparticles (NPs) are a kind of novel functional materials, which have been widely used in the biotechnology and catalysis. This review focuses on the recent development and various strategies in preparation, structure, and magnetic properties of naked and surface functionalized iron oxide NPs and their corresponding application briefly. In order to implement the practical application, the particles must have combined properties of high magnetic saturation, stability, biocompatibility, and interactive functions at the surface. Moreover, the surface of iron oxide NPs could be modified by organic materials or inorganic materials, such as polymers, biomolecules, silica, metals, etc. The problems and major challenges, along with the directions for the synthesis and surface functionalization of iron oxide NPs, are considered. Finally, some future trends and prospective in these research areas are also discussed.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Under hydrothermal conditions, it is difficult to control the final size of particles and most of the time polydisperse samples are obtained.

    “However, it is difficult to control the final size of particles and most of the times polydisperse samples are obtained under hydrothermal conditions [3, 28, 46].”
  • Amorphous SPION obtained from sonochemical synthesis need further heat-treatment after synthesis.

    “Thus, the obtained amorphous SPION need to be further processed by heat-treatment after they have been synthesized [3, 28, 46–48].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
