AbstractUnmethylated CpG oligodeoxynucleotides (CpG‑ODN) are powerful activators of innate and adaptive immunity, yet their rapid degradation in serum limits clinical utility. We engineered CpG‑MCA nanohydrogels by multi‑primed chain amplification (MCA), generating hydrogels rich in tandem CpG repea

AbstractGas‑sensing performance of graphene thin films is often limited by nanosheet stacking, which reduces surface accessibility. Here we introduce a novel ammonia (NH3) sensor that employs holey graphene oxide (HGO) thin films. HGO nanosheets are produced by UV‑assisted photo‑Fenton etching of gr

AbstractSulfur, nitrogen co-doped graphene quantum dots (S, N-GQDs) with high crystallinity were obtained by a top-down strategy. The as-prepared S, N-GQDs were investigated and the results indicate that S, N-GQDs exhibit a transverse dimension about 20 nm and a topographic height of 1–2 layers grap

AbstractCarbon nanotubes (CNTs) combine exceptional mechanical strength, high aspect ratio, large surface area, distinctive optical signatures, and superior thermal and electrical conductivity. These attributes make CNTs indispensable for electronics, energy storage, biomedicine, and advanced coatin

AbstractTransition‑metal oxides (TMOs) have attracted attention as pseudocapacitor electrodes because of their high theoretical capacitance, abundance, and environmental friendliness. However, their practical specific capacitance often falls short of theory, and volume changes during cycling comprom

AbstractEarly, precise detection of low‑abundance biomarkers is pivotal for pre‑emptive treatment of clotting disorders. We present a robust surface‑functionalization strategy that combines pre‑alkaline polystyrene activation, amine (APTES) modification, and gold nanoparticle (GNP) conjugation to im

Abstract Bufalin, a cardiac glycoside extracted from Venenum Bufonis, demonstrates strong antitumor activity but is limited by poor bioavailability and significant systemic toxicity when administered as a free drug. In this study we evaluated bufalin‑loaded PEGylated liposomes (BF/PEG‑LP) in terms o

AbstractThis study examines how a copper insertion layer and rapid thermal annealing (RTA) influence the resistive switching (RS) behavior of lanthanum‑based RRAM devices. Compared with the undoped Cu/LaAlO₃/Pt control, Cu‑embedded structures exhibit higher device yield and an elevated reset‑stop vo

Abstract Terahertz time‑domain spectroscopy (THz‑TDS) is rapidly becoming a cornerstone technique in non‑destructive evaluation, biomedicine, and secure communications. Yet, the development of robust, room‑temperature components that can generate, detect, filter, and modulate THz radiation remains a

Research HighlightsFunctional groups on GO drive both reduction and PEDOT polymerization without external

AbstractIn this study we formulated a resveratrol (RES)-loaded solid lipid nanoparticle (SLN‑RES) designed to improve insulin resistance by upregulating the SNARE protein complex in a rat model of type 2 diabetes. The optimized SLN‑RES displayed an average diameter of 248 nm, a zeta potential of –16

AbstractMalignant tumors remain a leading cause of mortality worldwide. Lymphatic vessel density correlates strongly with metastasis, yet current markers lack specificity and affordability. Here we report Fe3O4@KCTS core‑shell magnetic nanoparticles functionalized with both LYVE‑1 and podoplanin ant
