Carbon nanodots@zeolitic imidazolate framework-8 nanoparticles for simultaneous pH-responsive drug delivery and fluorescence imaging

A facile two-step method was developed to fabricate green fluorescent carbon nanodots@zeolitic imidazolate framework-8 nanoparticles (C-dots@ZIF-8 NPs) with tunable size and fluorescence intensity, which acted as platforms for simultaneous pH-responsive drug delivery and fluorescence imaging of cancer cells.
