Abstract: Optical biosensors offer several benefits over standard analytical methods, including the ability to directly and immediately detect biological substances in a practical and visually intuitive manner. Among the various optical signals utilizing colorimetric, fluorescent, or luminescent probes, our focus lies on colorimetric and fluorescent biosensors. We have utilized the chromatic and fluorogenic transitions of the conjugated polymer polydiacetylene (PDA) to create colorimetric sensors for protein, malignant exosome, and Pb²⁺ detection, as well as a cell imaging probe. Additionally, PDA serves as an alternative to conventional organic fluorescent dyes on a biochip platform. Furthermore, research has explored the utilization of fluorescent carbon quantum dots (CQDs) as imaging probes, drug carriers, sensors, antioxidants, and blockers for UV and high-energy blue light (HEBL). Due to their advantageous characteristics, such as easy production, low cost, technical simplicity, and speed, they exhibit significant potential as convenient and straightforward platforms for practical usage.
