Nowadays, the LSPR Accepted 4 September 2017 biosensing based on noble metal is still restricted in research laboratories, due to the limitations of their Available online 13 September 2017 intrinsic properties, high prime price, and high process cost. Researchers thereby have paid attention to the non-noble metals and semiconductor materials in recent years. This review focuses on the research Keywords: progress of non-noble-metal materials with nanostructures for plasmonic biosensing. Firstly, the Plasmonic biosensing physical and sensing principles of LSPR sensors are briefly introduced. Then, non-noble-metal materials, Localized surface plasmon resonance
