Development of Biosensors Based on the One-Dimensional Semiconductor Nanomaterials

Biosensors are becoming increasingly important due to their applications in biological and chemical analyses, food safety industry, biomedical diagnostics, clinical detection, and environmental monitoring. Recent years, nanostructured semiconductor materials have been used to fabricate biosensors owing to their biocompatibility, low toxicity, high electron mobility, and easy fabrication. In the present study, we focus on recent various biosensors based on the one-dimensional semiconductor nanomaterials such as electrochemical biosensor, field-effect transistors biosensor, and label-free optical biosensor. In particular, the development of the electrochemical biosensor is discussed detailedly.
