Synthesis of Dual-Color-Emitting Carbon Nanodots via Surface Modification with 4-Octyloxyaniline for Multicolor Bioimaging and Optogenetic Control of Ion Channels |
| 초록 |
The electronic structure engineering of carbon nanodots (CNDs) has been one of the great issue for their various fields of applications. Here, we have developed intrinsically multicolor-emitting CNDs which emit two distinct colors via the surface electronic structure engineering with 4-octyloxyaniline. The so-called dual-color-emitting CNDs (DC-CNDs) could be stably encapsulated within water-soluble poly(styrene-co-maleic anhydride) (PSMA) enabling biomedical applications to in vitro and in vivo dual-color bioimaging and optogenetics. In vivo optical imaging could visualize the biodistribution of intravenously injected DC-CNDs@PSMA. Moreover, DC-CNDs could be successfully exploited for optogenetic applications via the wavelength-dependent activation of ion channels. As a new type of fluorophore, DC-CNDs offer a big insight into the design of multicolor-emitting materials for various optical and biomedical applications. |
