Rose Bengal-derived pH-sensitive carbon quantum dots for the detection of urea and urease activity
In this work, rose Bengal-derived carbon quantum dots (S-CQDs) were prepared by a one-step solvothermal method in ethanol using rose Bengal and 2-aminothiophenol as raw materials. The morphological properties, surface functional group information, elemental composition and optical properties of S-CQDs were carefully ch...
