“…Given that base concentration, temperature, Fe 2+ /Fe 3+ proportion, value and ionic strength of the media, order of the reactants and the use of surfactants are factors that may interfere with the control of particle size, shape, composition and magnetic properties [ 34 , 35 ], recent studies have adapted the co-precipitation method in order to improve the properties of the nanoparticles [ 36 , 37 , 38 , 39 ]. For instance, through variations in the pH of the precipitates and in the amount of sodium hydroxide, spherical IONPs of different sizes can be obtained [ 40 ], taking advantage of the linear relation between IONPs diameter and pH, probably due to nanoparticle aggregation.…”

Medical applications and biotechnological advances, including magnetic resonance imaging, cell separation and detection, tissue repair, magnetic hyperthermia and drug delivery, have strongly benefited from employing iron oxide nanoparticles (IONPs) due to their remarkable properties, such as superparamagnetism, size and possibility of receiving a biocompatible coating. Ongoing research efforts focus on reducing drug concentration, toxicity, and other side effects, while increasing efficacy of IONPs-based treatments. This review highlights the methods of synthesis and presents the most recent reports in the literature regarding advances in drug delivery using IONPs-based systems, as well as their antimicrobial activity against different microorganisms. Furthermore, the toxicity of IONPs alone and constituting nanosystems is also addressed.

“…Recent years have witnessed unprecedented growth in the number of studies on the synthesis or application of magnetic nanoparticles (MNP). [1][2][3][4][5] Potential application may require different properties of the MNP; however, their monodispersibility with controlled size, stability, composition, magnetic properties, and functionality are critical for any application. Often transmission electron microscopy (TEM) and X-ray diffraction (XRD) are used to study the morphology and the size distribution of MNP.…”

The success of using the nanoparticles in various applications demands control over size, dispersibility, and magnetics. Hence, the nanoparticles are often characterized by transmission electron microscopy (TEM), X-ray diffraction, and magnetic hysteresis loops. TEM analysis requires a thin layer of dispersed particles on the grid, which may often lead to particle aggregation thus making size analysis difficult. Magnetic hysteresis loops on the other hand provide information on the bulk property of the material without discriminating size, composition, and interaction effects. First order reversal curves (FORCs), described as an assembly of partial hysteresis loops originating from the major loop are efficient in identifying the domain size, composition, and interaction in a magnetic system. This study presents FORC diagrams on a variety of well-characterized biogenic and synthetic magnetite nanoparticles. It also introduces deconvoluted reversible and irreversible components from FORC as an important method for obtaining a semi-quantitative measure of the effective magnetic particle size. This is particularly important in a system with aggregation and interaction among the particles that often leads to either the differences between physical size and effective magnetic size. We also emphasize the extraction of secondary components by masking dominant coercivity fraction on FORC diagram to explore more detailed characterization of nanoparticle systems.

“…In addition to MRI, magnetic nanoparticles have also been widely investigated as hyperthermal therapeutic agents and drug delivery agents in the past two decades because of their facile preparation, easy separation and site-specific accumulation ability [33,57,58]. Magnetic nanoparticles with controllable size, composition and shape can be synthesized via co-precipitation, thermal decomposition and hydrothermal reaction [59,60,61,62]. The synthesized magnetic nanoparticles are usually coated with organic molecules such as surfactants, polymers or inorganic shells (i.e., silica and carbon) to improve their stability and facilitate post-functionalization [63].…”

Inorganic nanoparticles have been widely investigated as therapeutic agents for cancer treatments in biomedical fields due to their unique physical/chemical properties, versatile synthetic strategies, easy surface functionalization and excellent biocompatibility. This review focuses on the discussion of several types of inorganic nanoparticle-based cancer therapeutic agents, including gold nanoparticles, magnetic nanoparticles, upconversion nanoparticles and mesoporous silica nanoparticles. Several cancer therapy techniques are briefly introduced at the beginning. Emphasis is placed on how these inorganic nanoparticles can provide enhanced therapeutic efficacy in cancer treatment through site-specific accumulation, targeted drug delivery and stimulated drug release, with elaborations on several examples to highlight the respective strategies adopted. Finally, a brief summary and future challenges are included.
