Designing and synthesizing multishelled metallic hollow nanostructures with intragaps porous shells have received widespread attention for enhancing optical catalytic properties. However, significant challenges remain in engineering these structures at the nanometer scale. Herein, we employed galvanic replacement reaction (GRR) method to prepare multimetallic superstructures 3D cavities distinct intragaps. By precise control of intragap distances (1–10 nm) composition distributions within a single entity, libraries were constructed. Using 4-nitrophenol reduction as model reaction, triple-shell Au@Pt–Ag nanoparticles approximately 1 nm exhibited rate 211.6 times higher than that commercial Pt/C catalysts. The nanoconfinement environment not only increases active sites but also promotes electron delocalization reactants, accelerating hydrogenation process both thermodynamically kinetically. Our work advances rational synthesis nanostructures, expanding their potential applications catalysis, plasmonics, biosensing.

Abstract Tumor immunotherapy exerts its anti-tumor effects by stimulating and enhancing immune responses of the body. It has become another important modality therapy with significant clinical efficacy advantages compared to chemotherapy, radiotherapy targeted therapy. Although various kinds tumor immunotherapeutic drugs have emerged, challenges faced in delivery these drugs, such as poor permeability low cell uptake rate, had prevented their widespread application. Recently, nanomaterials emerged a means for treatment different diseases due targeting properties, biocompatibility functionalities. Moreover, possess characteristics that overcome defects traditional immunotherapy, large drug loading capacity, precise easy modification, thus leading wide application immunotherapy. There are two main classes novel nanoparticles mentioned this review: organic (polymeric nanomaterials, liposomes lipid nanoparticles) inorganic (non-metallic metallic nanomaterials). Besides, fabrication method nanoparticles, Nanoemulsions, was also introduced. In summary, review article mainly discussed research progress based on past few years offers theoretical basis exploring strategies future.

Designing an effective treatment strategy to combat oral diseases caused by complex polymicrobial biofilms remains a great challenge. Herein, series of metal-phenolic network with Pd nanoparticle nodes using polyphenols as stabilizers and reducing agents is constructed. Among them, sulfonated lignin-Pd (SLS-Pd) ultrafine size palladium nanoparticles broadband near infrared absorption exhibit excellent oxidase-like activity stable photothermal effect. In vitro experiments demonstrate that the superoxide radical generated SLS-Pd exhibits selective antibacterial effects, while its effect induced hyperthermia potent antifungal properties. This difference further elucidated RNA-sequencing analysis all-atom simulation. Moreover, SLS-Pd-mediated synergistic antimicrobial system remarkable efficacy in combating various biofilms.

Breast cancer (BC) is a significant cause of cancer-related deaths among women worldwide. Hypoxia, common feature solid tumor, associated with drug resistance and poor prognosis in BC. In this study, we present strategy to overcome hypoxia-induced chemotherapy tolerance Specifically, synthesized hollow gold (Au)-platinum (Pt) bimetallic nanoshell for the first time, which acted as delivery system (DDS) doxorubicin (DOX). The photothermal effect, induced by surface plasmon resonance (SPR) from Au-Pt shell under near infrared-II (NIR-II) laser irradiation, not only directly causes tumor cell death through therapy (PTT), but also significantly enhances catalase-like activity between Pt nanoparticles endogenous H2O2. This, subsequently, results heightened yield O2, further facilitates release DOX. This process alleviates hypoxia down-regulating hypoxia-inducible factor-1α (HIF-1α), multidrug gene 1 (MDR1), P-glycoprotein (P-gp), can reverse achieve more effective DOX effects. Significantly, increased availability oxygen re-polarizes immunosuppressive M2 macrophages into antitumor M1 macrophages. study presents novel tackle proliferation enhance response chemotherapy, offering hope reversing cancerous lesions.
