We report a periodically patterned organization of hierarchical ZnO twin-crystals on a planar substrate in a biomimetic solution process. The deposition of the porous complex ZnO structure on specific sites of the substrate is achieved by introduction of the substrate surface modification and gelatin in a hydrothermal crystallization of ZnO.

Environmental issues arising from the low pesticide utilization rate make the development of environmentally friendly and low-cost pesticide carrier systems an urgent problem to be solved. Pickering emulsion systems have shown broad application prospects in pesticide delivery. In this study, dodecenyl succinic anhydride (DDSA) was used to hydrophobically modify cellulose nanofiber (D-CNF), and biomimetic flower-like zinc oxide (ZnO) particles were prepared by precipitation method at room temperature.

Optical patterning of colloidal particles is a scalable and cost-effective approach for creating multiscale functional structures. Existing methods often use high-intensity light sources and customized optical setups, making them less feasible for large-scale microfabrication processes. Here, we report an optical patterning method for semiconductor nanoparticles by light-triggered modulation of their surface charge.

Enhancement of the mechanical and biological properties of dental restoration materials is of significant importance. Drawing inspiration from the architecture and mechanical properties of natural nacre, we employed a low-cost accumulative rolling process to develop resin-ceramic composites with suitable hardness and high toughness. Plate-like aluminum oxide powder with diameters of 5-10 μm and nano-zinc oxide (ZnO) with antibacterial properties were mixed as the ceramic phase of the composite.

The present research aims to develop a Ca-Zn ion-incorporated surface functionalized 3D Ti cancellous bone scaffold for bone defect repair. The scaffold is designed to mimic human cancellous bone architecture through selective laser melting-based additive manufacturing. The chemical-based surface modification approach employed here created a Ca and Zn ions incorporated nano-porous surface layer with enhanced surface roughness and hydrophilicity.

Chronic refractory wounds have become a serious threat to human health and are characterized by prolonged inflammation, recurrent bacterial infections, and elevated ROS levels. However, current therapeutic strategies usually target a unilateral healing function and are unable to tackle the complexity and sensitivity of chronic refractory wound healing. This study fabricated a biomimetic nanozyme based on rhein (Cu-rhein NSs), which effectively mimics the activity of superoxide dismutase (SOD) for scavenging various free radicals.
