“…A modified version of AFM is magnetic force microscopy (MFM), which detects the magnetic fields for imaging down to 100 nm in resolution and can be employed to characterize and manipulate 1D and 2D nanomaterials. The operational principle of MFM is based on the quantification of long-range magnetostatic force, which is situated over the sample surface at a constant height between the magnetic sample and magnetically coated probe [31]. Furthermore, nanomaterial three-dimensional visualization is possible with confocal scanning laser microscopy (CSLM), as well as by observation of the interaction or distribution of the wall material by using fluorochromes that bind to specific functional groups of the target molecule [32].…”

Food science is constantly undergoing innovation, which is why the trend toward developing nanomaterials and their use in food matrices is increasing, mainly due to the physicochemical properties nanomaterials exhibit at the nanometric scale. Therefore, it is convenient to contextualize how these nanomaterials are obtained, classified, and characterized, including interactions that occur at the biomolecule–nanostructure interface, attributed to their physical, chemical, and mechanical properties. This review discusses how nanotechnology is linked naturally to food, including macro-, micro-, and nanostructures, and how the physicochemical properties of nanomaterials influence the food industry by substantially improving the antimicrobial effects, the bioavailability of compounds, and the development of packaging. Finally, the scope of nanotechnology is broad and includes the study of new materials and existing nanostructures in foods, as well as their effects on health. Thus, the physicochemical properties at the micro- and nano-level are essential for the development of and knowledge apportion in scientific nanofood research.

Single‐molecule fluorescence (smFL) imaging techniques have evolved greatly over the past two decades to encompass the ability to monitor chemical reactions, providing unique advantages of non‐invasive sample preparation and characterization, labeling specificity, and high spatial and temporal resolutions. This work summarizes the recent progress in this important area by first providing a brief overview of different smFL techniques, including their common optical setups and working principles. We then introduce recent developments of smFL to characterize various model chemical reaction systems, such as biochemical synthesis, catalyzed systems, and nanomaterial assembly. Furthermore, several representative areas of using smFL to understand polymer reactions are discussed, including understanding interfacial phenomenon and polymerization kinetics, as well as characterizing electrochemical reactions. We also highlight the outlook of this exciting field and potential opportunities for further development and application of smFL to enable advances in polymer chemistry and physics.

Halloysite nanotubes (HNTs) have a layered structure of clay silicate minerals and a tubular shape, which is suitable for the uniform loading of small substrates and drug molecules. The inner diameter of HNTs with an acidic solvent is selectively etched to increase the loading capacity of magnetic iron–platinum (FePt) nanoparticles. The FePt nanoparticles and etched HNTs (eHNT) are then composited by vacuum decompression. The resulting product is named FePt@eHNT and is used as a contrast agent for T2‐weighted magnetic resonance imaging. According to a comprehensive analysis of the material and its magnetic properties, by adding different proportions of HNTs before and after modification, the saturation magnetization can reach 23.769 emu g−1, which is higher than that of the composite materials studied in previous studies. This is because the tubular structure promotes the orderly displacement of the FePt nanoparticles under three‐dimensional space constraints and the uniform effect of the magnetic field. In addition, the magnetothermal effect of the composite material is observed and its potential as an imaging agent is investigated. In this study, the enhancement of its ferromagnetism and its potential to become a multifunctional composite material for applications in drug delivery, magnetic hyperthermia, and bioimaging is demonstrated.
