Polarized P(VDF-TrFE) film promotes skin wound healing through controllable surface potential

Zhiyuan Zhou et al.

Summary: The surface potential of biomaterials is crucial for wound healing. This study investigated the effect of surface potential on wound healing by preparing poly(vinylidenefluoride-co-trifluoroethylene) (P(VDF-TrFE)) films with different surface potentials and piezoelectric responses. The results revealed that electric polarization promotes the crystallization of the beta phase of P(VDF-TrFE) and high surface potential enhances protein adsorption, fibroblast proliferation, and macrophage polarization. In vivo experiments further demonstrated that high voltage polarized P(VDF-TrFE) films can generate a higher dynamic potential and significantly promote wound healing compared to the control group. Overall, this study provides insights into designing wound healing materials with similar properties.

Chemical interaction at the interface of metal-plastic direct joints fabricated via injection molded direct joining

Shuaijie Zhao et al.

Summary: This study discusses the chemical interaction between metal and plastic, showing that hydrogen bonds play a significant role in joining strength. By carefully controlling the surface texture and chemical conditions of aluminum plates, different joining strengths were observed, indicating the presence of chemical interactions between aluminum and polyamide 6 (PA6). The formation of hydrogen bonds between -CONH in PA6 and hydroxyl groups on the aluminum surface was confirmed by changes in IR spectra, although chemisorbed water on the surface may hinder this bond formation.

3D-Printed Regenerative Magnesium Phosphate Implant Ensures Stability and Restoration of Hip Dysplasia

Nasim Golafshan et al.

Summary: The study introduces a novel regenerative hip implant fabricated through a one-step process based on patient-specific design and load-bearing properties. The implant, made using a flexible, bone-inducing biomaterial and extrusion-assisted 3D printing, shows mechanical stability and degradation resistance. It can be fixed with metallic screws to host bone and withstand physiological loads, even after losing approximately 40% of its initial mass. Overall, the hip implant offers an innovative solution for hip dysplasia treatment with regenerative properties.
