Algal polysaccharide Sacran-based conductive nanocomposites for ultrathin flexible and biodegradable organic electrochemical transistors

Popis výsledku v původním jazyce

Organic electrochemical transistors (OECTs) have emerged as essential components in various applications, including bioelectronics, neuromorphics, sensing, and flexible electronics. Recently, efforts have been directed toward developing flexible and sustainable OECTs to enhance their integration into wearable and implantable biomedical devices. In this work, we introduce a novel PEDOT:Sacran bio-nanocomposite as a channel material for flexible and biodegradable OECTs. Sacran, a high-molecular-weight polysaccharide derived from blue-green algae, possesses exceptional ionic conductivity, water retention, and biocompatibility, making it a promising candidate for bioelectronic applications. We successfully fabricated ultrathin and flexible OECTs on poly(ethylene terephthalate) (PET) foils, achieving transconductance values up to 7.4 mS. The devices exhibited stable ion-to-electron transduction after mechanical deformation. The OECTs were further demonstrated on eco-friendly and biodegradable poly(lactic acid) (PLA) substrates, achieving a transconductance of 1.6 mS and undergoing enzymatic hydrolysis under controlled conditions. This study highlights the potential of Sacran-based conductive bio-nanocomposites in advancing sustainable bioelectronic devices.
