Conjugated Polymer based Optoelectronic Sensors for Health


This project concept is the development of integrated technologies (optical/electronics response) for the highest sensitivity solid-state biosensor to tackle the limitation of non-invasive global disease detection nowadays. Investigation of the conjugated polymer material, which are synchronous in both optical and electrical properties, is a main point to promote the dual sensor-based system. The research aims to optimize the synthesis of electrospun nanofibers by utilizing the optoelectronics function of conjugated polymer materials. This novel chemical material will be able to detect the various biomarkers simultaneously with dual detection system and subsequently combined with Organic Field Effect Transistor platform to establish lab-on-a-chip wearable device.
