Autologous nerve transplantation (ANT) is currently considered the gold standard for treating long-distance peripheral defects. However, several challenges associated with ANT, such as limited availability of donors, donor site injury, mismatched diameters, and local neuroma formation, remain unresolved. To address these issues comprehensively, we have developed porous poly(lactic-

Abstract Organic mixed ionic‐electronic conductors have emerged as a key material for the development of bioelectronic devices due to their soft mechanical properties, biocompatibility, and high volumetric capacitance. In particular, PEDOT:PSS has become choice because it is highly conductive, easily processible, commercially available. However, dispersible in water, leading delamination films when exposed biological environments. For this reason, chemical cross–linking agents such (3‐glycidyloxypropyl)trimethoxysilane (GOPS) are used stabilize but at cost decreased electrical performance. Here, shown that thin water‐stable by simply baking temperatures (>150 °C) short time (≈ 2 min).

Abstract Durable and conductive interfaces that enable chronic high‐resolution recording of neural activity are essential for understanding treating neurodegenerative disorders. These implants require long‐term stability small contact areas. Consequently, they often coated with a blend polymers crosslinked to enhance durability despite the potentially deleterious effect crosslinking on mechanical electrical properties.
