“…Therefore, it represents a promising technique to ameliorate conventional industrial electrolyzers, which are usually operated at macroscopic temperatures of ≈70–90 °C. Furthermore, a series of nanomaterials, such as Fe 3 O 4 , [ 130 ] MnFe 2 O 4 , [ 131 ] CoFe 2 O 4 , [ 132 ] CoMnSi alloy, [ 133 ] and NiFeCo alloy, [ 134 ] have manifested pronounced magnetic hyperthermia effect. They provide an intriguing material platform for further exploration of magnetic field‐promoted HER/OER in the forthcoming efforts.…”

promising alternative to fossil fuels. Water electrolysis by renewable resourcederived electricity represents a facile and green route to produce H 2. [1-13] Generally, the key to implement high-performance water splitting is to develop economically viable, efficient, and robust electrocatalysts to lower the activation potential barriers. Thus far, researchers have devoted extensive enthusiasm to the investigation of electrocatalysts. Currently, most efforts have been taken on the search for new materials, [14-16] regulation of morphology, [17] crystallinity, [18] facet, [19] component, [20-24] defect, [25,26] matter phase, [27,28] or the compositing of various materials with synergy. [29-36] However, the performances of emerging nonnoble electrocatalysts still lag behind those of noble ones. To address this issue, researchers have turned their attention beyond the electrocatalysts themselves. Field-assisted electrocatalysis is the electrocatalytic reaction proceeded in the presence of a field. It represents a promising methodology since it exerts an additional degree of freedom to engineer an electrochemical process. Inspiringly, indisputable improvements in electrocatalytic hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) have been implemented with the assist of various fields, including electric field, magnetic field, strain, and light. For example, the electrocatalytic HER of a MoS 2 nanosheet is markedly boosted by simply exploiting a back gate voltage of 5 V. [37] Its overpotential at −100 mA cm −2 is decreased from 240 to 38 mV. In addition, enhancement of alkaline water electrolysis is achieved by applying a moderate magnetic field (≤450 mT) to an electrocatalytic anode consists of highly magnetic electrocatalysts. [38] Its current density increments are beyond 100%. Furthermore, the HER activity of β-PdH x increases monotonically as the applied strain increases from 0% to 4.5%. [39] Lastly, an approximately threefold increase in current density of Au-MoS 2 for electrocatalytic HER is realized upon the illumination of IR light. [40] These results undoubtedly elucidate that applying a field during electrocataly sis opens up great opportunities toward further improving electrocatalytic activity. Moreover, this approach provides merits of facile, dynamical, continuous, reversible, and universal control. Despite fascinating achievements, these investigations are relatively scattered. The underneath mechanisms and principles Hydrogen fuel is considered as one of the most clean renewable resources, warranting it a primary alternative to fossil fuels for future energy supplies. Electrocatalytic water splitting is an eco-friendly technique for high-purity hydrogen production. However, the sluggish dynamics of its two halfreactions, hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), are tough challenges impeding the practical application of this technology. In these years, external field-assisted HER and OER have attracted extensive research interests. Herein, the effects o...

Hyperthermia (HT) is a rapid cancer therapy inducing cellular apoptosis by increasing the local temperature of cancerous tissues between 40 and 44°C. 1 The tumors are highly susceptible to this thermal range at which cancerous cells are destroyed, while the normal cells undergo no significant damaging effects. HT is induced by using magnetic materials under an alternating magnetic field (AMF). Benefitting from some favorable characteristics of magnetic nanomaterials (MNPs), magnetic HT has drawn enormous attention and reduced the adverse side effects related to conventional treatments of several tumors such as prostate, glioblastoma, and metastatic bone cancer. 1 This method is usually combined with other therapeutic approaches like chemotherapy (drug delivery), photothermal therapy, gene therapy, immunotherapy, and high-intensity focused ultrasound, which is critically discussed in this paper. 1 The exact process of HT is not yet fully understood since a variety of biological effects can simultaneously occur like heat-induced alteration of cells signaling pathways, DNA, and RNA alterations; expressions of heat-shock proteins; and many other biochemical changes, as well as the direct cytotoxic effect of heat. 2,3 Still, there is a theory which has been mostly accepted by scientists that the impaired vascularization of tumors, together with heat, leads to the lack of oxygen in the tumor environment. As a result, malignant cells escalate their anaerobic metabolism

“…Advancement of nanotechnology has extensively expedited the emergence of novel magnetic nanostructures by reducing the dimensions to 2D nanomaterials, such as thin films and supperlattices, or 1D nanomaterials, such as magnetic nanowires (MNWs), and even 0D, such as spherical magnetic nanoparticles. The excellent quantum efficiency achieved using these nanomaterials has made them useful building blocks for diverse research areas, including medical treatment [1][2][3][4][5], environmental science [6,7], and quantum devices [8][9][10][11]. These magnetic nanostructures have opened numerous opportunities for scientists in different disciplines such as nanomedicine, molecular biology [12][13][14], applied physics, and nanostructured materials [15][16][17][18][19][20].…”

The remarkable multimodal functionalities of magnetic nanoparticles, conferred by their size and morphology, are very important in resolving challenges slowing the progression of nanobiotechnology. The rapid and revolutionary expansion of magnetic nanoparticles in nanobiotechnology, especially in nanomedicine and therapeutics, demands an overview of the current state of the art for synthesizing and characterizing magnetic nanoparticles. In this review, we explain the synthesis routes for tailoring the size, morphology, composition, and magnetic properties of the magnetic nanoparticles. The pros and cons of the most popularly used characterization techniques for determining the aforementioned parameters, with particular focus on nanomedicine and biosensing applications, are discussed. Moreover, we provide numerous biomedical applications and highlight their challenges and requirements that must be met using the magnetic nanoparticles to achieve the most effective outcomes. Finally, we conclude this review by providing an insight towards resolving the persisting challenges and the future directions. This review should be an excellent source of information for beginners in this field who are looking for a groundbreaking start but they have been overwhelmed by the volume of literature.
