The highly efficient peroxidase‐like activity of platinum nanozymes (3–20 nm size) is exploited within the complex cellular environment to catalyze oxidation DAB substrate, producing an electron‐dense signal around nanozyme surface, upon osmium staining. It proved that such amplification can achieve a catalytic enhancement up 10‐fold, enabling quick detection Pt particles (even 3 by transmission electron microscopy (TEM) also at low magnification and across wide fields view in intricate intracellular milieu. developed procedure ideally suited overcome standard strategies currently used TEM analysis, as gold or silver enhancements. Furthermore, versatility Pt‐nanozyme probes imaging demonstrated immuno‐EM protein trafficking studies, showing their potential track subcellular localization target biomolecules both high magnifications. These results suggest use might represent paradigm shift conventional systems employed for analyses, offering enhanced capabilities.

Abstract Topical eyedrop administration is identified as an ideal non‐invasive strategy for ocular drug delivery. However, multiple complex barriers greatly restrict their effectiveness in the treatment of posterior disease. Herein, a liposome‐based permeable eyedrops (pDrops) capable overcoming and achieving efficient delivery presented. pDrops have core‐shell structure which drugs are encapsulated inside liposome core with chitosan shell. This coating significantly enhances pDrops’ binding to mucin tears facilitates temporary opening tight junctions cornea/conjunctive epithelial cells, thereby prolonged preocular retention enhanced segment In this study, hydrophilic ganciclovir (GCV) hydrophobic curcumin (CUR) employed model drugs. Upon topical instillation, effectively overcome delivered GCV both rat rabbit eyes. Notably, CUR by demonstrates therapeutic efficacy light‐damaged retina mice. Considering that can deliver eye, it potentially become feasible platform various molecules improve efficiency diseases.

Nanozymes (NZs) are nanomaterials able to mimic natural enzymes, offering the advantages of better durability, wider range operational conditions, and easier functionalization. In addition, some NZs exhibit multiple enzyme‐like activities effective tandem/self‐cascade reactions. this context, metallic metal–oxide nanoparticles among most promising candidates for biomedical/biotechnological applications, thanks their efficient oxidoreductase activities. However, characterizing is challenging because experimental set‐up different assays strongly influence performances. Consequently, currently available literature provides limited understanding characteristics various NZs, especially in terms activity‐related performance, hindering optimal selection applicative potential. Here, leveraging on accurate characterization methodology, we report a direct comparison several (gold‐Au, platinum‐Pt, palladium‐Pd, ceria, iron oxide) possessing multi‐enzymatic Our main findings indicate that 1) PtNZs outperform other tested catalase‐like activity; 2) Pt PdNZs present superior superoxide dismutase‐like 3) peroxidase‐ oxidase‐like activity, best‐performing NZ substrate‐dependent; 4) competitive reactions multifunctional play key role specific AuNZs can be choice peroxidase/oxidase configurations; 5) more than metal‐oxide ones, but 6) ceria presents unique phosphatase‐like activity.
