摘要

Single atomically thick graphene,with unique structural flexibility,surface sensitivity,and effective light-mater interaction,has shown exceptional advances in optoelectronics.It opens a door for diverse functionalized photonic devices,ranging from passive polarizers to active lasers and parametric oscillators.Among them,graphene-fiber biochemical sensors combine the merits of both graphene and fiber structures,demonstrating impressively high performances,such as single-molecule detectability and fast responsibility.These graphene-fiber biochemical sensors can offer tools in various applications,such as gas tracing,chemical analysis,and medical testing.In this paper,we review the emerging graphene-fiber biochemical sensors comprehensively,including the sensing principles,device fabrications,systematic implementations,and advanced applications.Finally,we summarize the state-of-the-art graphene-fiber biochemical sensors and put forward our outlooks on the development in the future.
