Urinary extracellular vesicles (uEVs) are regarded as highly promising liquid-biopsy biomarkers for the early diagnosis and prognosis of bladder cancer (BC). However, detection uEVs remains technically challenging owing to their huge heterogeneity ultralow abundance in real samples. We herein present a choline phosphate-grafted platinum nanozyme (Pt@CP) that acts universal EV probe construction high-throughput high-sensitivity immunoassay, which allowed multiplex profiling uEV protein markers BC detection. With Pt@CP-based immunoassays, three (MUC-1, CCDC25, GLUT1) were identified BC, by cases (n = 48), cystitis patients 27), healthy donors 24) discriminated with high clinical sensitivity specificity (area under curve 98.3%). For 9) after surgery, immunoassay could report postoperative residual tumor cannot be observed cystoscopy, is clinically significant assessing recurrence. This work provides generally detection, facilitating discovery use EV-based biomarkers.

As an indispensable part of the human sensory system, visual acuity may be impaired and even develop into irreversible blindness due to various ocular pathologies. Among diseases, fundus neovascularization diseases (FNDs) are prominent etiologies impairment worldwide. Intravitreal injection anti-vascular endothelial growth factor drugs remains primary therapy but is hurdled by common complications incomplete potency. To renovate current therapeutic modalities, nanomedicine emerged as times required, which endowed with advanced capabilities, able fulfill effective drug delivery achieve precise release control, thus further improving effect. This review provides a comprehensive summary advances in for FND management from state-of-the-art studies. First, modalities FNDs thoroughly introduced, focusing on key challenges delivery. Second, nanocarriers comprehensively reviewed posterior based nanostructures: polymer-based nanocarriers, lipid-based inorganic nanoparticles. Thirdly, characteristics microenvironment, their pathological changes during FNDs, corresponding strategies constructing smart elaborated. Furthermore, prospects discussed.

Nanozymes, characterized by their nanoscale size and enzyme-like catalytic activities, exhibit diverse therapeutic potentials, including anti-oxidative, anti-inflammatory, anti-microbial, anti-angiogenic effects. These properties make them highly valuable in nanomedicine, particularly ocular therapy, bypassing the need for systemic delivery. Nanozymes show significant promise tackling multi-factored diseases, those influenced oxidation inflammation, like dry eye disease, age-related macular degeneration. Their small size, coupled with ease of modification integration into soft materials, facilitates effective penetration barriers, thereby enabling targeted or prolonged therapy within eye. This review is dedicated to exploring diseases that are intricately linked shedding light on role nanozymes managing these conditions. Additionally, recent studies elucidating advanced applications therapeutics, along materials disease management, discussed. Finally, this outlines directions future investigations aimed at bridging gap between nanozyme research clinical applications.

Gold nanoclusters (AuNCs) exhibit unique physicochemical properties but their functional transitions under external stimuli remain underexplored. This study reveals that ultraviolet (UV) irradiation triggers structural evolution in AuNCs, causing fluorescence loss while activating dual enzyme-mimetic activities. UV-induced particle enlargement and surface restructuring endow AuNCs with peroxidase-like (POD-like) laccase-like functionalities. The POD-like activity enables sensitive glucose detection human serum, the capability facilitates simultaneous degradation of phenolic pollutants wastewater. These light-responsive transformations demonstrate AuNCs' dynamic adaptability, bridging intrinsic catalytic properties. findings elucidate photo-regulation mechanisms nanomaterial functionality, proposing a novel strategy for designing multifunctional nanosystems applicable biosensing environmental remediation. work advances development adaptive nanomaterials programmable features biomedical ecological applications.
