    An Improved Synthesis of Water-Soluble Dual Fluorescence Emission Carbon Dots from Holly Leaves for Accurate Detection of Mercury Ions in Living Cells by Wang P, Yan Y, Zhang Y, Gao T, Ji H, Guo S, Wang K, Xing J, Dong Y

    Published 2021-03-01
    “…However, the Hg2+ detection of CDs was limited because of the insufficient water solubility, low fluorescence and poor stability.Methods: Dual fluorescence emission water-soluble CD (Dual-CD) was prepared through a solvothermal method from holly leaves and low toxic PEI1.8k. PEG was further grafted onto the surface to improve the water solubility and stability.Results: The Dual-CD solution can emit 487 nm and 676 nm fluorescence under single excitation and exhibit high quantum yield of 16.8%. …”
