Investigating the Impact of Copper-PEDOT:PSS Matrix towards Nonenzymatic Electrochemical Creatinine Detection

Chirantan Das, Subhrajit Sikdar, Shreyas Vasantham, Piotr Pięta et autres

Abstract Electrochemical creatinine sensors offer great promise toward rapid, reagent-free, and point-of-care (POC) kidney-function monitoring. However, challenges related to analyte binding, data reproducibility, sensitivity, fouling, and device degradation deter their widespread implementation. Here, we show how a carbon electrode modified with a …

Enhancing Conductivity in 3D Organic Electrochemical Transistors with PEDOT–Tetramethacrylate Integration

Viktorija Reinikovaite, İpek Sarıer, Martin Jönsson‐Niedziółka, Nehar Celikkin et autres

Electroconductive hydrogels offer a unique combination of conductivity and biocompatibility, mimicking the extracellular matrix for bioelectronic applications. Herein, we present a homogeneous, conductive, and cytocompatible hydrogel-based organic electrochemical transistor (OECT) composite, combining methacrylated gelatin (GelMA), PEDOT:PSS, and tetramethacrylated PEDOT:TOS (PEDOT-TMA:TOS). This three-component …
