Inflammatory bowel disease (IBD) is a chronic inflammatory disease of the gut that has caused an escalating burden on the global healthcare system in recent years. Researchers have been actively seeking innovative therapeutic strategies to combat this intractable disease. Recent advances in nanozyme technology have opened up new avenues for the development of novel therapeutic strategies for IBD. This review provides a comprehensive overview of the related works in the developments and applications of different nanozymes for IBD therapy. By overviewing the known pathogenesis of IBD and pathogenesis-guided applications of nanozymes in IBD therapy, this review highlights the opportunities for nanozyme-based strategies to address IBD via the underlying mechanisms. This review also examines the current state of nanozyme research in IBD, including the design and application of nanozymes, and discusses the challenges and future directions for this emerging field. In addition, by integrating the understanding of IBD pathogenesis with the development of nanozyme technology, this review aims to stimulate further research to uncover new opportunities for this debilitating disease.

Holoferritin is considered a promising iron supplement, yet its preparation is challenging due to low extraction efficiencies from natural sources and the potential for structural damage during in vitro mineralization. This study reported the in vivo biosynthesis of a highly stable holoferritin (bs-holoFt) in Escherichia coli a high iron-loading capacity (1213 Fe atoms/protein) and systematically characterized the impact of heat treatments (70-100 °C) on the protein's multi-level structure and dual functions. Results showed a clear, temperature-dependent degradation pathway, initiated by the loss of α-helical content (decreased from 77.

Liver fibrosis, a pivotal pathological stage in the progression of chronic liver diseases to cirrhosis and hepatocellular carcinoma is characterized by liver sinusoidal endothelial cell (LSEC) capillarization, oxidative stress imbalance, and cell pyroptosis. Current clinical interventions show limited efficacy in reversing fibrosis, highlighting the urgent need for novel therapeutic strategies. In this study, we developed an L-arginine-loaded melanin-like nanozyme (L-Arg@MeNPs) that targets liver fibrosis through a triple-action mechanism: (1) sustained nitric oxiderelease from L-Arg restores LSEC fenestration, improving sinusoidal permeability; (2) the MeNPs exhibit catalase/superoxide dismutase-mimicking activity to scavenge reactive oxygen species, thereby blocking the NOD-like receptor pyrin domain-containing 3/caspase-1-mediated pyroptosis pathway; and (3) intrinsic photoacoustic/magnetic resonance dual-modal imaging enables real-time therapeutic monitoring.

Current colorimetric sensing arrays for antioxidant detection often struggle with discrimination due to cross-reactive signals from individual nanozymes. These signals are typically modulated by external factors such as pH or chromogenic substrates, offering limited kinetic and mechanistic diversity. To overcome this, we present a novel triple-channel colorimetric sensing array utilizing two distinct single-atom nanozymes (Cu SA and Fe SA) and one dual-atom nanozyme (CuFe DA).

An one-pot method was used to prepare bimetallic nanozymes, with chitosan (CS) and l-tyrosine (L-Tyr) as stabilized dispersed colloidal solutions and a carrier for gold-platinum single atoms (Au-Pt SAs), which exhibited excellent peroxidase activity. A colorimetric method based on CS/L-Tyr/Au-Pt SAs nanozymes was constructed for the colorimetric detection of quercetin (QR) in human serum and orange juice. The synthesized bimetallic nanozymes were characterized by SEM, TEM, HAADF-STEM, FT-IR, XRD and XPS techniques to demonstrate the successful synthesis of CS/L-Tyr/Au-Pt SAs nanozymes.
