Prussian blue nanoparticles (PBNPs) have been identified as a promising candidate for biomimetic peroxidase (POD)-like activity, specifically due to the metal centres (Fe3+/Fe2+) of (PB), which potential function catalytically active centres. The decoration PBNPs with desired functional polymers (such amino- or carboxylate-based) primarily facilitates subsequent linkage biomolecules their use in biosensor applications. Thus, elucidation catalytic POD mimicry these systems is significant scientific interest but has not investigated depth yet. In this report, we studied series poly(ethyleneimine) (PEI)-mediated (PB/PEI NPs) prepared using various synthesis protocols. resulting range particles varying size (~19–92 nm) and shape combinations were characterised order gain insights into physicochemical properties. POD-like nanozyme activity was then by utilising 3,3′,5,5′-tetramethylbenzidine (TMB)/H2O2 system, performance natural enzyme horseradish (HRP) serving point comparison. It shown that most PB/PEI NPs displayed higher than PBNPs, observed smaller size, Fe content, Fe2+/Fe3+ ratio. Furthermore, demonstrated enhanced chemical stability presence acid, sodium azide, high concentrations H2O2 when compared HRP, confirming viability nanozymatic material. This study disseminates fundamental knowledge on activities, will facilitate selection an appropriate particle type future

Nanozymes have shown significant potential in cancer catalytic therapy by strategically catalyzing tumor-associated substances and metabolites into toxic reactive oxygen species (ROS) situ, thereby inducing oxidative stress promoting cell death. However, within the complex tumor microenvironment (TME), rational design of nanozymes factors like activity, reaction substrates, TME itself significantly influence efficiency ROS generation. To address these limitations, recent research has focused on exploring that affect activity developing nanozyme-based cascade systems, which can trigger two or more processes tumors, producing therapeutic achieving efficient stable with minimal side effects. This area remarkable progress. Perspective provides a comprehensive overview nanozymes, covering their classification fundamentals. The regulation nanozyme strategies are discussed detail. Furthermore, representative paradigms for successful construction systems treatment summarized focus revealing underlying mechanisms. Finally, we current challenges future prospects development biomedical applications.

Fast-charging technology, which reduces charging time and enhances convenience, is attracting attention. Sodium-ion batteries (SIBs) potassium-ion (PIBs) are emerging as viable alternatives to lithium-ion (LIBs) due their abundant resources low cost. However, during fast discharging, the crystal structures of cathode materials in SIBs/PIBs can be damaged, negatively impacting performance, lifespan, capacity. To address this, there a need explore electrode with ultrahigh rate capabilities. Prussian Blue its analogues (PB PBAs) have shown great potential for both SIBs PIBs unique excellent electrochemical properties. This Review examines use PBAs PIBs, focusing on fast-charging (rate) performance commercialization potential. Through systematic analysis discussion, we hope provide practical guidance developing contributing advancement widespread adoption green energy technologies.

In contrast to homogeneous enzyme catalysis, nanozymes are nanosized heterogeneous catalysts that perform reactions on a rigid surface. This fundamental difference between enzymes and is often overlooked in kinetic studies practical applications. this article, using 14 of various compositions (core@shell, metal-organic frameworks, metal, metal oxide nanoparticles), we systematically demonstrate nontypical features nanozymes, such as multiple catalytic activities, chemical transformations, aggregation, need be considered nanozyme catalysis. Ignoring these results the inaccurate quantification activity. Neglecting activities led six-time underestimation Mn

Abstract The core strategies in treating rheumatoid arthritis (RA) now focus on ameliorating the inflammatory microenvironment and reversing macrophage phenotypes within joint cavity. This study introduces a co‐delivery system of integrating nanoenzymes gene therapeutics sequentially modified with guanidinium‐based polymers membranes to achieve synergistic therapeutic effects. is named MACP siTNF‐α nanoparticles (NPs). are designed for targeted delivery inflamed site, where they preferentially internalized by M1‐type macrophages efficiently evade lysosomal degradation. Subsequently, operates via self‐sustaining positive feedback drug release mechanism. biomimetic nanoplatform reduces reactive oxygen species (ROS) levels prevents glutathione (GSH) depletion. GSH degrades small interfering RNA (siRNA) expose Prussian blue (PB) nanoenzymes, which effectively scavenge ROS restore levels. loop significantly enhances silencing capability scavenging efficiency system. In summary, NPs can reverse ecological niche soils through dual mechanism inhibiting expression tumor necrosis factor‐alpha (TNF‐α) upstream pathway response, eliminating ROS, thus realizing efficient treatment RA.

Diabetic wound healing presents a significant medical challenge and requires multistep interventions due to comprehensive environments, such as hyperglycemia, bacterial infection, impaired angiogenesis. However, current are complicated need on-demand sequential release synergy of multicomponents. Herein, H2S-releasing cascade nanozyme (FeS@Au), which is composed ultrasmall gold nanocluster (AuNC) loaded on ferrous sulfide nanoparticle (FeSNP), developed single component regulate glucose level, eliminate promote angiogenesis, achieving for diabetic treatment. The oxidase-like activity AuNC catalyzes into gluconic acid H2O2, not only lowers the local level but also decreases pH increases H2O2 boost peroxidase-like FeSNP generate abundant hydroxyl radical (reactive oxygen species, ROS), inducing ferroptosis-like death in drug-resistant bacteria. Additionally, H2S acidified environment upregulate hypoxia-inducible factor-1 enhance vascularization through upregulating expression vascular endothelial growth factor (VEGF) other angiogenesis-related genes, reducing damage cells caused by excessive ROS produced nanozyme. In full-thickness MRSA-infected rat model, FeS@Au significantly eliminates bacteria, enhances promotes collagen deposition, accelerates healing. This work with H2S-release interventions, providing versatile strategy extensive tissue diabetes.

Abstract Depression, a severe disorder affecting both physical and mental health, is commonly treated with first‐line antidepressants, which often exhibit limited efficacy due to poor penetration of the blood‐brain barrier (BBB) significant side effects, thus requiring exploitation biocompatible effective treatments. Recent studies suggest that depression closely linked an imbalance in oxidative stress subsequent inflammatory responses. Antioxidant therapies targeting are therefore emerging as promising strategies. In this study, exosome‐functionalized geniposide (GEN) self‐carried Prussian blue (PB) nanotherapeutic approach fabricated realize efficient BBB for synergistic therapy. The porous PB carrier possesses multi‐enzyme capabilities, can effectively scavenge accumulated ROS, protecting slightly acidic environment released GEN from oxidation, subsequently works simultaneously activate Nrf2‐ARE pathway, enhancing body's defense mechanisms synergistically. triple‐amplified anti‐oxidant strategy nanomaterial shown mitigate microglial activation reduction neuroplasticity, ultimately alleviating pathological markers depression. Overall, constructed nanomaterials underscore therapeutic potential anti‐oxidative removal ROS pathway treatment
