The rapid development of advanced nanotechnology has continuously changed many aspects of society. One important nanostructured material, magnetic nanoparticles (NPs), has applications in many areas including clean energy, biology and engineering because of their special magnetic properties. The synthesis of magnetic nanomaterials with desired sizes and morphology has attracted great attention. Nanomaterials with different properties can be combined to construct multifunctional nanoplatforms through systematic surface engineering. The surface modification of magnetic NPs presents the opportunity for them to be used in many practical applications. Functionalized magnetic NPs have been successfully applied in catalysis, as thermoelectric materials, for drug delivery, as imaging agents in nuclear magnetic resonance and in biosensors. In this review, synthetic methods for magnetic NPs and some of their important properties are described. Then the latest progress of the application of magnetic NPs in energy and biology has been summarized and discussed. Finally, we discuss some issues that still need to be solved and the prospects for magnetic NPs.

Coating synthetic nanoparticles (NPs) with lipid membranes is a promising approach to enhance the performance of nanomaterials in various biological applications, including therapeutic delivery to target organs. Current methods for achieving this coating often rely on bulk approaches which can result in low efficiency and poor reproducibility. Continuous processes coupled with quality control represent an attractive strategy to manufacture products with consistent attributes and high yields.

Solar evaporation exhibits significant potential for the treatment of high-salt organic wastewater. However, it's also confronted with challenges due to the accumulation of organic pollutants and salts in the concentrated wastewater following evaporation, which compromises the long-term stability of evaporation unit and complicates subsequent treatment processes. To address these challenges, a volumetric solar interfacial evaporation (V-SIE) system by integrating FeO HO nanofluids and peroxydisulfate (PDS) were proposed in this study.

Unlabelled: Today, nanoplastics (NPs) are a growing environmental concern due to their persistence and widespread distribution, posing risks to ecosystems and human health. Their ability to transport pollutants makes them particularly dangerous, underscoring the urgent need for effective removal methods. Herein, we report the synthesis of an environmentally friendly material that enables the magnetic removal of polystyrene nanoparticles (PSNPs) from aqueous solutions by green chemistry approach.

Objective: To explore the possible mechanism of absorption of iron oxide nanoparticles into the human body through the gastrointestinal tract.
Methods: This article used Caco-2 monolayer cells as a cell model, prepared characterized iron oxide nanoparticles(Fe_2O_3 NPs) as suspensions, and intervened in Caco-2 cells. CCK-8 method, transwell method, and atomic spectrophotometer method were used to explore the effect of Fe_2O_3 NPs on the activity of Caco-2 cells and the absorption and transport of them through the Caco-2 monolayer cell model.

Cancer is a deadly disease with complex pathophysiological nature and is the leading cause of death worldwide. Traditional diagnosis methods often detect cancer at a considerably critical stage and the conventional methods of treatment like chemotherapy, radiation therapy, targeted therapy, and immunotherapy have several limitations, multidrug resistance, cytotoxicity, and lack of specificity are a few examples. These pose substantial challenge for effective and favourable cancer treatment.
