“…a factor of 10) when the particle concentration increases from 0.00028% to 0.0112%. The value of SAR for gold nanoparticle under such a low heat flux is larger than many magnetic nanoparticles under high magnetic fields, which typically in the order of one hundred Watt per gram of magnetic nanoparticle [17][18][19] .…”

This work proposes and validates a novel idea of using plasmonic nanoparticles (PNP) to improve the solar thermal conversion efficiency. Gold nanoparticle (GNP) is synthesized from an improved citrate-reduction method, and used as an example to illustrate the photothermal conversion characteristics of PNPs under a solar simulator. The experimental results show that GNP has the best photo-thermal conversion capability comparing to other reported materials. At the lowest particle concentration examined (i.e., 0.15 ppm), GNP increases the photo-thermal conversion efficiency of the base fluid by 20% and reaches a specific absorption rate (SAR) of ~10 kW/g. The photo-thermal conversion efficiency increases with increasing particle concentrations, but the SAR shows a reverse trend, which is unexpected as all GNPs should be still in the independent scattering regime.

“…[708] Although the biocompatibility of iron oxide has made it to one of the most desirable MNP used in hyperthermia, [642c] larger sizes of such MNPs are more prone to aggregation and have more difficulties in penetrating and dispersing within tumors. [709] For smaller sizes of iron oxide nanoparticles, the total heating efficiency regarding with hysteresis loss is reduced as a result of decrease in the saturation magnetization, [710] while Brownian and Neel relaxations become the relevant mechanisms to generate heat. [642c] Specifically, the rapid rotation of the particles themselves within a medium account for Brownian relaxation which is hindered by the viscosity of the medium to peter out the movement of particles.…”

In order to translate nanotechnology into medical practice, magnetic nanoparticles (MNPs) have been presented as a class of non‐invasive nanomaterials for numerous biomedical applications. In particular, MNPs have opened a door for simultaneous diagnosis and brisk treatment of diseases in the form of theranostic agents. This review highlights the recent advances in preparation and utilization of MNPs from the synthesis and functionalization steps to the final design consideration in evading the body immune system for therapeutic and diagnostic applications with addressing the most recent examples of the literature in each section. This study provides a conceptual framework of a wide range of synthetic routes classified mainly as wet chemistry, state‐of‐the‐art microfluidic reactors, and biogenic routes, along with the most popular coating materials to stabilize resultant MNPs. Additionally, key aspects of prolonging the half‐life of MNPs via overcoming the sequential biological barriers are covered through unraveling the biophysical interactions at the bio–nano interface and giving a set of criteria to efficiently modulate MNPs' physicochemical properties. Furthermore, concepts of passive and active targeting for successful cell internalization, by respectively exploiting the unique properties of cancers and novel targeting ligands are described in detail. Finally, this study extensively covers the recent developments in magnetic drug targeting and hyperthermia as therapeutic applications of MNPs. In addition, multi‐modal imaging via fusion of magnetic resonance imaging, and also innovative magnetic particle imaging with other imaging techniques for early diagnosis of diseases are extensively provided.
