The development of new methods for applications of detection in the biological field is a topic of intense and growing interest. The currently practiced methods for biological detection have many defects, such as time-consuming, low accuracy, and cumbersome for operators. Gold nanorods (AuNRs) have received tremendous attention recently in the fields of biological detection owing to the unique characteristics of surface plasmon resonance (SPR), which provides a remarkable ability to absorb and scatter light. Furthermore, AuNRs can be functionalized with a wide variety of biomolecules for targeted detection. Moreover, their versatility and unique properties have generated more applications in medical areas. In this review, we briefly outline the synthesis and surface modification of AuNRs, and focus on the recent advances of the application of AuNRs in detection field. Finally, the outlook and future prospect on the development of AuNRs are provided.
