Chiral nanocomposite for highly selective dual-mode sensing and bioimaging of hydrogen sulfide

With the continuous development of nanotechnology, more artificial chiral nanomaterials have been constructed. As one of the most representative optical properties of these chiral nanomaterials, circular dichroism (CD) is a powerful sensing technology. Compared with other analytical methods, CD signal has higher sensitivity, but it cannot achieve in-situ imaging in vivo.
