Various biomaterials such as antibody, aptamer, enzyme, DNA and sensory receptor can be used for recognizing ligands by nanobiosensor. Especially, olfactory sensing elements with olfactory receptor are most promising one to develop the nanobiosensor with high performance because they can discriminate target molecules with high selectivity and also detect numerous odorant molecules, for example over ten thousands of odorants at very low concentration can be detected by human nose. There have been increasing many efforts to develop the nanobiosensor using various olfactory sensing elements. Recently, several olfactory sensing elements were integrated with nanomaterials, which greatly improve the sensitivity of the nanobiosensor, to enhance the performance of nanobiosenor. In this paper, olfactory sensing elements were briefly introduced for the development of the nanobiosensor with high performance.
