Fig. 5From: Plant Cell Imaging Based on Nanodiamonds with Excitation-Dependent FluorescenceConfocal fluorescence images of mung bean stem cells cultivated in the solution with 1 mg mL−1 of NDs for 48 h. Panels a–c were obtained under excitations 405 nm, 488 nm, and bright field, respectively. d The overlayer of the images in b and c proved that NDs invaded the cell cytoplasm. The emissions were recorded in different ranges: a 480–550 nm and b 600–680 nmBack to article page
