Organic Materials and Devices for Biosensing and Neuromorphic Computing

Dear Colleagues,

In recent years, organic materials and devices have played an increasingly important role in biosensing applications. These materials offer advantages such as flexibility, biocompatibility, and tunable electronic properties, making them ideal for developing next-generation biosensors. Organic-based biosensors have been widely explored for detecting biomolecules, monitoring physiological signals, and diagnosing diseases with high sensitivity and specificity. Integrating organic electronic materials into biosensors has enabled advances in wearable, implantable, and point-of-care diagnostic systems.

A key aspect of organic biosensing technologies is their ability to interface with biological systems in a soft and flexible manner. Organic field-effect transistors (OFETs), organic electrochemical transistors (OECTs), and organic photodetectors have demonstrated promising results in detecting biomarkers, neurotransmitters, and physiological changes. Additionally, emerging organic bioelectronic platforms have paved the way for real-time and non-invasive health monitoring. These innovations have the potential to improve early disease detection and personalized medicine.

Beyond traditional biosensing applications, organic materials and devices also contribute to neuromorphic computing, an area inspired by the brain's information-processing mechanisms. Organic neuromorphic devices can mimic synaptic functions and process biological signals in a way that closely resembles neural networks. This intersection between biosensing and neuromorphic computing is particularly exciting for applications such as brain–machine interfaces and intelligent diagnostics.

For this Special Issue, we welcome original research articles and reviews on the latest advancements in organic materials and devices for biosensing. Topics of interest include, but are not limited to, the following:

• The development of high-sensitivity and selective organic biosensors for medical diagnostics and health monitoring.
• Innovations in organic electrochemical and field-effect transistors for biomolecular detection.
• Flexible and wearable organic biosensing devices for real-time physiological monitoring.
• Theoretical and experimental studies on organic bioelectronic interfaces.
• The role of organic materials in neuromorphic-inspired biosensing and intelligent diagnostic platforms.

We invite contributions that explore novel materials, fabrication techniques, and application-driven studies that push the boundaries of organic biosensing technology. Both experimental and theoretical studies are encouraged to provide a comprehensive understanding of the field and its future prospects.
