Monitoring acetylcholinesterase (AChE) activity and its inhibitor is crucial yet challenging for the early diagnosis treatment of neurological diseases. In this study, we present Au nanoparticle decorated CoAl layered double hydroxide monolayer (Au@CoAl-LDH-m) as a peroxidase-like (POD) nanozyme sensitive colorimetric detection AChE inhibitor, thiamine pyrophosphate (TPP). Remarkably, Au@CoAl-LDH-m can catalyze oxidation chromogenic substrates through POD-like activity, which effectively inhibited by thiocholine (TCh, catalytic product AChE), thereby enabling TPP visible readout. The approach provides highly specificity assay with broader linear response range (1-100 mU mL

Abstract: Given the complexity of central nervous system (CNS) and diversity neurological conditions, increasing prevalence disorders poses a significant challenge to modern medicine. These disorders, ranging from neurodegenerative diseases psychiatric not only impact individuals but also place substantial burden on healthcare systems society. A major obstacle in treating these conditions is blood-brain barrier (BBB), which restricts passage therapeutic agents brain. Nanotechnology, particularly use nanoparticles (NPs), offers promising solution this challenge. NPs possess unique properties such as small size, large surface area, modifiable characteristics, enabling them cross BBB deliver drugs directly affected brain regions. This review focuses application gene therapy enzyme replacement (ERT) for disorders. Gene involves altering or manipulating expression can be enhanced by designed carry various genetic materials. Similarly, improve efficacy ERT lysosomal storage (LSDs) facilitating delivery brain, overcoming issues like immunogenicity instability. Taken together, explores potential revolutionizing treatment options highlighting their advantages future directions rapidly evolving field. Keywords: system, nanoparticle, therapy,

Solanesol (Sol) and chlorogenic acid (CHA) are naturally active compounds. Sol exhibits a significant free radical absorption ability strong antioxidant activity. CHA, typical phenolic acid, excellent anticancer, anti-inflammation, antibacterial properties. Herein, bifunctional nanomicelles (CI@SPK) were skillfully designed to take advantage of the unique properties CHA treat Alzheimer's disease (AD). Hydrophobic was modified with poly(ethylene glycol) self-assemble into stable (SP). could be encapsulated hydrophobic core these nanomicelles, which increased its bioavailability greatly. Short peptide K (CKLVFFAED) incorporated facilitate their crossing blood-brain barrier. Then, CI@SPK targeted AD lesion area, released in greater quantities help IR780 under irradiation an 808 nm laser, resulting synergistically scavenging reactive oxygen species (ROS) Sol. Consequently, demonstrated capabilities ROS, inhibiting β-amyloid (Aβ) aggregation, eventually modulating microglia phenotype from M1 M2 promote Aβ phagocytosis clearance. In vivo studies indicated that improved learning cognitive impairments APP/PS1 mice by reducing plaque inflammation, signifying potential value clinical application for treatment.

Protein function investigation and clinical assay are fundamental to modern biology medical diagnostics. Flap endonuclease 1 (FEN1), a key enzyme in DNA replication repair, plays critical role the progression of many diseases. Taking FEN1 as an example, we present novel protein detection platform combining triboelectric nanogenerator (TENG) CRISPR/Cas technologies. As specific form TENG, transistor-droplet electricity generator (TDEG) is explored, which offers low-cost, simple fabrication approach with real-time capability. Meanwhile, activated system catalyzes reactions on three-dimensional tetrahedron interface, promising high sensitivity. This work not only demonstrates powerful method for rapid but also pioneers integration TENG. It has great prospect future development TENG sensors.

Abundant ·OH, 1O2, and ·O2- provide an efficient methodology for rapid tumor bacteria killing, whereas a limitation focuses on the catalytic efficiency. Thus, Jahn-Teller-driven electronic modulation of bioheterojunction (bioHJ) platform is developed remedy in diabetic infectious wound regeneration after postoperative resection. The bioHJ composed MoTe2/MnO2 glucose oxidase (GOx). GOx depletes to H2O2, which intercepts their metabolism. H2O2 can be further converted into highly lethal ·OH owing peroxidase-mimetic activity via Jahn-Teller effect, while GSH consumed due its GPx-mimetic activity. Both amplified upon NIR irradiation as NIR-activatable enzyme-mimetic activities. In vivo studies subcutaneous model authenticate ability kill tumor, defeat bacterial infection, accelerate regeneration. This work enlightens powerful resection using engineered bioHJ.
