Advances in Optical Fiber Aptasensor for Biochemical Sensing Applications (Adv. Mater. Technol. 16/2023)

Optical Fibers Aptasensors fiber has attractive characteristics of fine diameter, soft texture, light weight, intrinsic safety and high biocompatibility, as reported by Ya-nan Zhang, Yong Zhao, co-workers in article 2300137. Specific aptamers modified the optical sensing region can specifically capture target analyte blood environment, such cytochrome C. This biological binding event cause changes output signal, thereby achieving purpose detection.
