MIL-101/CDs/MIL-101 for potential fluorescence imaging and pH-responsive drug delivery

A composite MIL-101/CDs/MIL-101 comprising MIL-101 and carbon quantum dots (CDs) was prepared and characterized. The particles were uniform in size and found to be potentially used for fluorescence imaging. Cytotoxicity assays indicated the particles were biocompatible and suitable for carrying drugs. In the drug release experiments, the MIL-101/CDs/MIL-101 demonstrated an excellent pH-triggered drug release.
