Nanoscale Prussian Blue and Its Analogues: Design and Applications in Infection Control, Wound Healing and Beyond

Prussian blue nanoparticles (PBNPs) have gained significant attraction in the field of nanomedicine due to their excellent biocompatibility, potential for nanoscale production, exceptional photothermal conversion ability, and multi-enzyme mimicking capabilities. PBNPs have made considerable advancements in their application to biomedical fields. This review embarks with a comprehensive understanding of the physicochemical properties and chemical profiling of PB-based nanoparticles, discussing systematic approaches to tune their dimensions, shapes, and sizes, as well as their biomedical properties. Subsequently, the use of PB-based NPs in the biomedical sector is extensively discussed and categorized based on the various features of modified PBNPs, either in combination with drugs or their analogues. Finally, the article highlights the existing challenges associated with current studies and explores the latest developments in these rapidly evolving PB-based nanoplatforms and their therapeutic potentials. Overall, this review aims to deepen the understanding of PB-based NPs and provide crucial insights into their rational design in disease treatment.

Carbon Foam-Supported VS2 Cathode for High-Performance Flexible Self-Healing Quasi-Solid-State Zinc-Ion Batteries

As the new generation of energy storage systems, the flexible battery can effectively broaden the application area and scope of energy storage devices. Flexibility and energy density are the two core evaluation parameters for the flexible battery. In this work, a flexible VS₂ material (VS₂ @CF) is fabricated by growing the VS₂ nanosheet arrays on carbon foam (CF) using a simple hydrothermal method. Benefiting from the high electric conductivity and 3D foam structure, VS₂ @CF shows an excellent rate capability (172.8 mAh g^-1 at 5 A g^-1 ) and cycling performance (130.2 mAh g^-1 at 1 A g^-1 after 1000 cycles) when it served as cathode material for aqueous zinc-ion batteries. More importantly, the quasi-solid-state battery VS₂ @CF//Zn@CF assembled by the VS₂ @CF cathode, CF-supported Zn anode, and a self-healing gel electrolyte also exhibits excellent rate capability (261.5 and 149.8 mAh g^-1 at 0.2 and 5 A g^-1 , respectively) and cycle performance with a capacity of 126.6 mAh g^-1 after 100 cycles at 1 A g^-1 . Moreover, the VS₂ @CF//Zn@CF full cell also shows good flexible and self-healing properties, which can be charged and discharged normally under different bending angles and after being destroyed and then self-healing.
