“…225 Hydrothermal synthesis involves using an autoclave with Teon-lined stainless steel walls, typically containing water in a supercritical/sub-supercritical state. 222,223,226 This method operates under high temperature and pressure conditions, resulting in oxidation and hydrolysis reactions that produce MNPs of uniform size. Synthesis parameters affect crystallinity, crystallite size, particle size, purity, and magnetic properties.…”

“…The coating should improve the stability and solubility of MNPs, increase their biocompatibility and target specificity, and prevent agglomeration, oxidation, corrosion, and toxicity [17][18][19][20][21][22][23]. The MNPs can be synthesized through many different methods including coprecipitation [24][25][26][27][28][29][30], thermal decomposition [31][32][33][34][35], hydrothermal synthesis [36][37][38][39][40], microemulsion [41][42][43][44], polyol reduction [45][46][47][48][49], the sol-gel method [50][51][52][53][54], and others [55][56][57][58][59][60][61][62][63]. The synthesized MNPs are usually coated to ensure a proper surface coating and develop some effective protection s...…”

This concise review delves into the realm of superparamagnetic nanoparticles, specifically focusing on Fe2O3, Mg1+xFe2−2xTixO4, Ni1−xCux, and CrxNi1−x, along with their synthesis methods and applications in magnetic hyperthermia. Remarkable advancements have been made in controlling the size and shape of these nanoparticles, achieved through various synthesis techniques such as coprecipitation, mechanical milling, microemulsion, and sol–gel synthesis. Through this review, our objective is to present the outcomes of diverse synthesis methods, the surface treatment of superparamagnetic nanoparticles, their magnetic properties, and Curie temperature, and elucidate their impact on heating efficiency when subjected to high-frequency magnetic fields.

“…While they are not metallic, they are a mixed valence oxide. One can prepare them from iron precursors with appropriate valence, such as co-precipitation [36], hydrothermal synthesis [37,38], microemulsion [39,40], or oxidation from ferrous precursors [41]. Reductive methods can also be used, such as the polyol process [42], thermal decomposition [43,44], or combustion method [45].…”

Poly(tartaric acid) is a relatively recently described polymer that can be easily synthesized and scaled up from a readily available renewable material (tartaric acid). This article demonstrates its use in a green synthesis of gold nanoparticles, silver nanoparticles, copper particles, and magnetite nanoparticles. In this case poly(tartaric acid) acts both as a reductant and as a coating agent. To our knowledge this is the first green synthesis of several different types of nanoparticles using only one reagent (polytartrate) as both reductant and coating. The resulting particles were analyzed by XRD, TEM/SEM, EDX, FTIR, DLS, zeta-potential, XPS, and UV/VIS spectroscopy. Preliminary studies of the thermal behavior of mixtures of different types of particles with poly(tartaric acid) were also conducted. The obtained particles show different sizes depending on the material, and the coating allows for better dispersibility as well as potential further functionalization, making them potentially useful also for other applications, besides the inclusion in polymer composites.
