The treatment of irregular-shaped and critical-sized bone defects poses a clinical challenge. Deployable, self-fitting tissue scaffolds that can be implanted by minimally invasive procedures are promising solution. Toward this, we fabricated NIR-responsive programmable polylactide-co-trimethylene carbonate (PLMC) nanoengineered with polydopamine nanoparticles (PDA) extrusion-based three-dimensional (3D) printing. 3D-printed demonstrated excellent (>99%), fast (under 30 s), tunable shape recovery under NIR irradiation. PLMC-PDA composites significantly higher osteogenic potential

Inspired by the transpiration in tree stem having a vertical and porous channel structure, high efficiency of formaldehyde removal is realized multi-scale micro-nano structure hybrid P(AAm/DA)-Ag/MgO hydrogel coating cross-linked on microfiber-based polyurethane. The present formed joint effect directional freezing redox polymerization as well nanoparticles-induced porosity. Due to large number vertically aligned channels micrometer size an embedded nanometer size, specific surface area significantly increased. Therefore, from solution can be rapidly adsorbed amine group hydrogels efficiently degraded Ag/MgO nanoparticles. By only immersing (0.2 mg mL-1) for 12 h, 83.8% removed with which 60.8% faster than that observed without any structure. After cross-linking polyurethane exposing vapor atmosphere, 79.2% again 11.2% higher Unlike traditional approaches remove light catalyst, no external conditions are required our coating, very suitable indoor use. In addition, due formation free radicals nanoparticles, synthetic leather also shows good anti-bacterial capability. 99.99% Staphylococcus aureus killed surface. Based ability kill bacteria, obtained containing used broad field applications, such furniture car interior parts, simultaneously solve air pollution hygiene problems.
