Carbonized polymer dots with dual‐wavelength emission for labeling nucleoli in live cells through hydrogen bonding‐induced aggregation

We prepared carboxyl‐containing carbonized polymer dots (CPDs) with dual‐wavelength emission through a simple hydrothermal method. The CPDs emit blue light in live cells under the excitation at 405 nm, and show green fluorescence in cytoplasm and nucleoli when excited at 488 nm. No fluorescence can...
