Abstract

Nanowires (NWs) are one-dimensional nanomaterials with a very high surface-area-to-volume ratio, as well as good durability, which have attracted researchers for use in sensing materials. The advancement of nanowire manufacturing processes and modification methods have made nanowire-based biosensors viable in a wide variety of research fields, counting protein biomarker discovery, metal ion detection, and drug discovery. Nanowires are best suited for biomedical sensors due to their high sensitivity, homogeneity, reproducibility, scalability, and easy fabrication process. This review evaluates an array of nanowire-based biosensors suitable for detecting a wide range of biological compounds. We expect to see more advancements in nanowire research and biosensor development in near future.
