The Role of Ultra‐Thin Buffer Layers for Achieving Ultra‐Low Dark Currents in Single‐Component Organic Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
Here, SubNc single‐component organic photodiodes (SC‐OPDs) are investigated, which achieve highly competitive performance metrics, including high EQE, ultra‐low JD, and high specific detectivity (D*). This study emphasizes the critical role of an organic buffer layer in studying the interface energetics and effects to achieve state‐of‐the‐art ...

Spatiotemporal Drug Delivery via a Neonatal Spinal Cord ECM Hydrogel for Biomimetic Microenvironment Remodeling After Spinal Cord Injury

open access: yesAdvanced Functional Materials, EarlyView.
A biomimetic hydrogel derived from neonatal spinal cord ECM (DNSCM) delivers LAMB2 protein and ISP peptide to remodel the inhibitory injury microenvironment. The system sustains drug release, upregulates pro‐regenerative LAMB2, downregulates inhibitory CSPG, and promotes axonal regeneration.
