Summary: Magnetic iron oxide nanoparticles have broad potential applications in medical and biological sciences. They can be used in targeted drug delivery, internal radiotherapy, magnetic resonance imaging, hyperthermia, and radiolabelling. The appropriate design of nanoparticles allows them to be delivered to desired tissues and organs, with an external magnetic field increasing their biodistribution. Factors such as size, shape, surface charge, coating molecules, and route of administration affect their biodistribution. Modern techniques can determine nanoparticle accumulation sites and concentration in isolated tissues or the body in vivo.

Summary: This study addresses the low sensitivity issue of spherical Au nanostructures in harsh chemical environments for LSPR sensing applications by developing a stable and high refractive index-sensitive Au-graphene-layered hybrid (Au G). The relationship between stability and sensitivity of the developed system is analyzed using principal component analysis, revealing that the shelf life of the material is proportional to its sensitivity, while the stability of the sensor during liquid measurement decreases with increased sensitivity. This work serves as a benchmark in understanding and establishing new correlations between sensing parameters.

Summary: Pulsed electrolysis can significantly enhance CO2 reduction on metal electrodes, but its effect on molecular electrocatalysts with short voltage steps remains largely unexplored. In this study, we investigate how pulse electrolysis affects the selectivity and stability of the homogeneous electrocatalyst [Ni(cyclam)](2+) on a carbon electrode. By tuning the potential and pulse duration, we achieve a remarkable improvement in CO Faradaic efficiencies (85%) after 3 hours, doubling that of the system under potentiostatic conditions. This research demonstrates the potential of applying pulsed electrolysis to molecular electrocatalysts for controlling activity and improving selectivity.

Summary: This study develops a simple one-step protein immobilization strategy to attach proteins covalently on the sensor surface, ensuring close attachment to the transducer surface. The effectiveness of this strategy is evaluated by comparing it with silane chemistry, colorimetric assays, and field effect devices. The performance of this methodology is also evaluated for the detection of glucose oxidation using a field effect device. Overall, the developed immobilization strategy avoids the effects of the debye length and improves the performance of the biosensor.

Summary: Understanding the mechanical changes in a mutated virus's single protein and its relation to point mutations is crucial for developing new inhibitory routes to control the virus's uncontrollable spread. In this study, the chemomechanical features of a single spike protein in the alpha, beta, and gamma variants of SARS-CoV-2 were quantified using integrated amplitude-modulation atomic force microscopy and dynamic force-distance curve spectroscopy. These nanomechanical properties can be correlated with individual protein mutations, providing new insights into the relationship between the mechanical properties of a single spike protein and viral functions. Furthermore, single-protein nanomechanical experiments have the potential to enhance our understanding of protein biochemistry during virus evolution.

Summary: This study investigates the enhanced localized surface plasmon resonance (LSPR) phenomena in nanomushroom structures and reveals the association with a hidden plasmonic mode through magneto-optics measurements and deconvolution analysis. By using principal component analysis, an explicit relationship among the deconvoluted modes of LSPR, differential absorption, and refractive index sensitivity of the LSPR sensor is observed. These findings may contribute to the development of new approaches for extracting unknown properties of plasmonic materials or establishing new fundamental relationships among less understood photonic properties of nanomaterials.

Summary: This study demonstrates the generation and detection of localized surface plasmon resonance (LSPR) wavelength shifts in large-area nanostructured gold surfaces using frictional charges generated by triboelectric surfaces. The interplay between localized surface plasmons and frictional charges is observed and analyzed through spectroscopic and triboelectric measurements, as well as theoretical models and surface characterization. The concept of electrification of plasmon resonance provides the foundation for the development of self-powered nano-plasmonic sensors and opens new possibilities for advanced nanophotonic applications.

Summary: Doped carbon materials, especially F-doped carbon catalysts, have gained significant attention as metal-free catalysts for oxygen reduction reactions and as corrosion-resistant supports for Pt and non-Pt nanoparticles. F-doped carbon materials possess unique properties and greatly improve the activity and durability of the ORR compared to N-doped carbon materials. The high electronegativity of F-doping can efficiently modify the electronic band structure of carbon materials, favoring the ORR. This review systematically discusses the effect of F-doping/F co-doping on the electrocatalytic reduction of O2 in acidic and alkaline conditions, the stability and durability of fuel cell catalysts, and provides guidelines for working with F-doped carbons. Future research directions on F-doped carbons are also proposed to bridge the gap between laboratory-scale assessments and commercial applications.
