Wafer‐Scale Dendritic Nanoporous Platinum Films for Neural Electrodes
Advanced Science, EarlyView.Wafer‐scale dendritic nanoporous platinum films with intrinsic nanoscale porosity are synthesized by suraface‐confined wet chemistry and transferred onto flexible substrates to create tissue‐conformal neural electrodes. The ultrathin films combine mechanical flexibility with electrochemical stability, enabling low‐impedance, high‐capacitance interfaces

Advanced Science, EarlyView.Orthodontic compression suppresses PIAS3 expression in cementoblasts, impairing ALOX15 SUMOylation and ubiquitin‐mediated degradation, which leads to ALOX15 accumulation, lipid peroxidation, ferroptosis, and osteoclastogenesis. Local delivery of PIAS3 circRNA‐loaded lipid nanoparticles restores the PIAS3–ALOX15 regulatory pathway, alleviates ...
