The classical 3D-printed scaffolds have attracted enormous interests in bone regeneration due to the customized structural and mechanical adaptability defects. However, pristine still suffer from absence of dynamic bioactive microenvironment that is analogous natural extracellular matrix (ECM) regulate cell behaviour promote tissue regeneration. To address this challenge, we develop a black phosphorus nanosheets-enabled DNA hydrogel integrate with scaffold build gel-scaffold construct...
Novel antimicrobial nanocomposite incorporating halloysite nanotubes (HNTs) and silver (Ag) into zinc oxide (ZnO) nanoparticles is prepared by integrating HNTs decorating Ag nanoparticles. ZnO (ZnO NPs) (Ag with a size of about 100 8 nm, respectively, are dispersively anchored onto HNTs. The synergistic effects NPs, led to the superior antibacterial activity Ag-ZnO/HNTs nanocomposites. facilitated dispersion stability NPs brought them in close contact bacteria, while could promote separation...
Dynamic hydrogels have attracted enormous interest for bone tissue engineering as they demonstrate reversible mechanics to better mimic biophysical cues of natural extracellular matrix (ECM) compared traditional static hydrogels.

Herein, we report a dual nanoengineered...
Abstract Bilayer graphene (BLG) is intriguing for its unique properties and potential applications in electronics, photonics, mechanics. However, the chemical vapor deposition synthesis of large-area high-quality bilayer on Cu suffering from a low growth rate limited coverage.
