Aqueous phase photon upconversion using a post-encapsulation strategy with hollow mesoporous silica microcapsules |
| 초록 |
We developed new vehicles for aqueous phase photon upconversion using a post-encapsulation strategy with hollow mesoporous silica microcapsules. The prepared silica microcapsules possess tunable diameters, large interior cavities, and ordered radial mesochannels that favor the controlled encapsulation of guest molecules. The upconversion oil is readily encapsulated at high loadings into the microcapsules. We successfully demonstrated cell-mediated triplet-triplet annihilation upconversion system by incorporating our microcapsules with human mesenchymal stem cells, which showed promise system for tumor-targeted low-power bioimaging. To the best of our knowledge, this study is the first to design biocompatible triplet-triplet annihilation upconversion system with a post-encapsulation strategy and diverse functionalities, thereby establishing a new and general platform to achieve efficient aqueous phase triplet-triplet annihilation upconversion system for multifunctional applications. |
