Cellular uptake mechanism of the quantum probe. A Schematic representation of the endocytosis mechanism. B Enhanced SERS signal for cancer and non-cancer cells. Magenta, cyan and green represent SERS signal and black spectra for non-SERS response. C Cell TEM reveal time-dependent cellular uptake of the quantum probes. Scale bar \(=10 \mu m\).
