Fig. 5From: A Brief Review of Carbon Dots–Silica Nanoparticles Synthesis and their Potential Use as Biosensing and Theragnostic Applicationsa Schematic representation of the multifunctional nanoplatform of silica–CDs. b The nanoplatform is localized in the cytoplasm, and the signal is due to the red CDs. All (b1–b4) images were obtained by confocal microscopy. Reproduced with permission from reference [247]. Copyright 2017 Royal Society of ChemistryBack to article page
