Hyperspectral observation of the treatment for 4T1 cells with CMMP. a Dark-field hyperspectral image of CMMP, the RGB vertical lines represented the "true color" wavelengths: red = 640 nm, green = 550 nm and blue = 460 nm. b Hyperspectral images for cells mapped with CMMP at 100 μg/mL. c Cell viability of 4T1 cells treated with MW, CDDP and CMMCP plus MW. Different concentrations of CMMCP (50, 100 and 200 μg/mL) and corresponding CDDP (6.15, 12.3, and 24.6 μg/mL) were incubated with 4T1 cells for 24 h and then cell viability was detected. *** indicates p < 0.001
