Abstract The previous studies mainly focused on improving microwave absorbing (MA) performances of MA materials. Even so, these designed materials were very difficult to be employed in complex and changing environments owing their single-functionalities. Herein, a combined Prussian blue analogues derived catalytical chemical vapor deposition strategy was proposed produce hierarchical cubic sea urchin-like yolk–shell CoNi@N-doped carbon (NC)-CoNi@carbon nanotubes (CNTs) mixed-dimensional multicomponent nanocomposites (MCNCs), which composed zero-dimensional CoNi nanoparticles, three-dimensional NC nanocubes one-dimensional CNTs. Because good impedance matching attenuation characteristics, the CoNi@NC-CoNi@CNTs MCNCs exhibited excellent performances, achieved minimum reflection loss ( RL min ) −71.70 dB at 2.78 mm Radar Cross section value −53.23 m 2 . More importantly, acquired results demonstrated that presented photothermal, antimicrobial anti-corrosion properties structure, highlighting potential multifunctional applications. It could seen this finding not only generalizable route magnetic NC-CNTs-based MCNCs, but also provided an effective develop improve environmental adaptabilities.

The rise of multi-drug-resistant (MDR) bacteria poses a severe global threat to public health, necessitating the development innovative therapeutic strategies overcome these challenges. Copper-based nanomaterials have emerged as promising agents due their intrinsic antibacterial properties, cost-effectiveness, and adaptability for multifunctional approaches. These materials exhibit exceptional potential in advanced therapies, including chemodynamic therapy (CDT), photothermal (PTT), photodynamic (PDT). Their unique physicochemical such controlled ion release, reactive oxygen species (ROS) generation, tunable catalytic activity, enable them target MDR effectively while minimizing off-target effects. This paper systematically reviews mechanisms through which Cu-based enhance efficiency emphasizes specific performance field. Key factors influencing properties—such electronic interactions, characteristics, size effects, ligand single-atom doping, geometric configurations—are analyzed depth. By uncovering copper-based nanomaterials, this work aims inspire approaches that improve patient outcomes, reduce burden bacterial infections, health initiatives.
