“…They found that these samples have high bacterial capture efficiency in the pH range 4–10 [ 200 ]. Recently, Karimzadeh et al developed a novel method for the synthesis of amino acid modified Fe 3 O 4 NPs based on CED [ 210 ]. Sahoo et al have described that citric acid can adsorb on the surface of magnetite NPs through the coordination of one or two carboxylate functional groups [ 211 ].…”

Functionalized iron oxide nanoparticles (IONPs) are of great interest due to wide range applications, especially in nanomedicine. However, they face challenges preventing their further applications such as rapid agglomeration, oxidation, etc. Appropriate surface modification of IONPs can conquer these barriers with improved physicochemical properties. This review summarizes recent advances in the surface modification of IONPs with small organic molecules, polymers and inorganic materials. The preparation methods, mechanisms and applications of surface-modified IONPs with different materials are discussed. Finally, the technical barriers of IONPs and their limitations in practical applications are pointed out, and the development trends and prospects are discussed.

“…Furthermore, these magnetic data are comparable with those of undoped IONPs electro‐synthesized at the similar electrochemical conditions. The reported magnetic data for undoped IONPs were Ms = 72.96 emu g −1 , Mr = 0.95 emu g −1 , and H Ci = 14.61 G . Comparing the data revealed that Ho 3+ doped IONPs exhibited lower Ms compared with undoped IONPs, which can be connected to the lower magnetism Ho element compared with Fe one.…”

A novel one-step electro-chemical synthesis platform is developed for the preparation of Ho 3þ doped iron oxide nanoparticles (Ho-IONPs). In this procedure, Ho-IONPs are electro-synthesized from an additive-free aqueous solution of mixed Fe(NO 3 ) 3 Á 9H 2 O, FeCl 2 Á 4H 2 O, and HoCl 3 Á 6H 2 O with applying dc current density of 10 mA cm À2 for 30 min. The characterization data provided by X-ray diffraction (XRD), field emission electron microscopy (FE-SEM) and energy-dispersive X-ray (EDX) confirmed that the synthesized Ho-IONPs have composition of magnetite crystal structure doped with 20 wt.% Ho 3þ cations and average particles size of about 10 nm. The electrochemical results obtained galvanostatic charge-discharge (GCD) tests showed that Ho-IONPs could provide specific capacitance as high as 222 F g À1 at discharging condition of 0.5 A g À1 , and 95.6% capacity retention after 1000 GCD cycling, which confirmed the suitability of the electro-synthesized Ho-IONPs for use in supercapacitors. The results of vibrating sample magnetometer measurements confirmed better superparamagnetic behavior of Ho-IONPs (Mr ¼ 0.14 emu g À1 and H Ci ¼ 2.37 G) as compared with pure IONPs (Mr ¼ 0.95 emu g À1 and H Ci ¼ 14.62 G) resulting from their lower Mr and H Ci values. Based on the obtained results, the developed electro-synthesis method is introduced as a facile procedure for the preparation of high performance metal ion doped magnetite nanoparticles.

“…A high surface-to-volume ratio induces a tendency to agglomeration and renders nanoparticles highly sensitive to oxidizing agents, resulting in them reacting easily with chemicals. Adequate selection of the synthesis method, as well as surface coating, may limit aggregation, promote dispersibility in water, and enable further functionalization of the particles, which is vital for their biomedical application [21][22][23]. Hydrophobic coatings enable the dispersibility of particles in various nonpolar solvents and limit their aggregation, which leads to better monodispersity of their sizes, thereby allowing controlled properties [24][25][26].…”

“…By applying a magnetic field, such carriers are able to achieve the desired position in a more precise and controllable way [29,30]. Furthermore, such platforms can also be used for magnetically controlled (bio)reactors, enabling reactions between components transported via facile magnetic remoting, even with nanoliter volumes [21][22][23][24][25][26][27][28][29][30][31][32][33][34]. We only recently presented polymer-based nanocapsules stabilized using a modified polysaccharide with an oleic acid liquid containing suspended MNPs, showing that they can be navigated using a static magnetic field [34].…”

This paper reports the characterization of iron oxide magnetic nanoparticles obtained via the thermal decomposition of an organometallic precursor, which were then loaded into nanocapsules prepared via the emulsification process in the presence of an amphiphilic derivative of chitosan. The applied synthetic method led to the formation of a hydrophobic layer on the surface of nanoparticles that enabled their loading in the hydrophobic liquid inside of the polymer-based capsules. The average diameter of nanoparticles was determined to be equal to 15 nm, and they were thoroughly characterized using X-ray diffraction (XRD), magnetometry, and Mössbauer spectroscopy. A core-shell structure consisting of a wüstite core and maghemite-like shell was revealed, resulting in an exchange bias effect and a considerable magnetocrystalline anisotropy at low temperatures and a superparamagnetic behavior at room temperature. Importantly, superparamagnetic behavior was observed for the aqueous dispersion of the nanocapsules loaded with the superparamagnetic nanoparticles, and the dispersion was shown to be very stable (at least 48 weeks). The results were analyzed and discussed with respect to the potential future applications of these nanoparticles and nanocapsules based on biopolymers as platforms designed for the magnetically navigated transport of encapsulated hydrophobic substances.
