As a new member of antibody industry, nanobodies have been rapidly developing in the field of immunoassay in the recent years. Nanobodies have valuable properties such as small molecular weight, high stability, high affinity and specificity, and high-quality production by prokaryotic expression system, etc. The application of nanobody reagents have improved the issues of traditional monoclonal antibody-based detection reagents, such as difficulties of reagent transportation and storage, higher costs of research and development, or larger differences among product batches, and also increased the detection sensitivity. Therefore, nanobodies have shown a wide application prospect in immunoassay. This article reviews the structure, characteristics and the recent research progress in immunoassay of nanobody, and envisages a prospect for the future of nanobody-based immunoassay.
