WO3-based electrochemical transistors (ECTs) are recognized as candidates for three-terminal memristors due to their high on–off ratio, long retention time, and rapid switching speed. However, patterned fabrication often relies on complex vacuum systems or extreme processing conditions, hindering cost-effective scalability. Here, we developed a novel wet etching technique integrated with sol–gel-derived WO3 channels, enabling ambient-air of Nafion-WO3 ECTs. The wet-etched devices achieve an ratio ~105, surpassing unetched dry-etched counterparts by orders magnitude. Furthermore, they exhibit exceptional paired-pulse facilitation long-term stability, maintaining 12 distinct conductance states 103 s, ~102 over 25 read–write cycles. XPS result shows higher W5+ content M-O-H bond proportion devices, revealing optimized interface, enhanced H+ injection efficiency. simulated artificial neural network using this ECT ~97% recognition accuracy handwritten numerals. This approach offers patterning strategy developing cost-effective, high-performance neuromorphic devices.

Parkinson’s disease (PD), a neurodegenerative disorder marked by the progressive loss of dopaminergic neurons in substantia nigra, imposes substantial economic burdens, including both direct and indirect costs. The medical community currently lacks definitive cure for disease, early detection is crucial timely intervention management. As innovative diagnostic tools, biosensors have shown great potential detecting PD at its stages. This review comprehensively summarizes recent advances PD, with particular focus on two key biomarkers: dopamine (DA) α-synuclein (α-syn). Furthermore, it illustrates variety nanotechnology-based biosensors, optical, electrochemical, transistor detailing their underlying principles, advantages, limitations, applications detection. Moreover, explores challenges prospects advancing diagnosis.
