Abstract: Biological imaging is an essential means of disease diagnosis. However, semiconductor quantum dots that are used in bioimaging applications comprise toxic metal elements that are nonbiodegradable, causing serious environmental problems. Herein, we developed a novel ecofriendly solvothermal method that uses ethanol as a solvent and doping with chlorine atoms to prepare highly fluorescent graphene quantum dots (GQDs) from seaweed. The GQDs doped with chlorine atoms exhibit high-intensity white fluorescence. Thus… Show more

“…Li et al [ 79 ] prepared Cl-GQDs (average particle size: 3.95 nm, QY: 28%) with white fluorescence by subjecting seaweed dispersed in a mixture of ethanol and chloroform to high-temperature, high-pressure treatment ( Figure 6 E). By adding an aqueous Cl-GQDs solution to HeLa cells, cell imaging revealed blue, green, purple, and red fluorescence under 405, 488, 543, and 633 nm excitation, respectively.…”

“…The diagnostic method, bioimaging, is connected with the penetration of drugs and diagnostic agents into tissues and cells and the sensitivity of detection. Bioimaging is controlled by biodegradability, biocompatibility, specificity, and applicability for carbon nanotubes [68][69][70][71][72][73][74][75][76][77][78][79][80][81], graphene [82][83][84][85][86][87][88][89][90][91][92][93][94], fullerenes [95], and dots [96].…”
