Figure 19. (A) The synthesis of GSH-CDs, Fe₃O₄ NPs and M-CDs; (B)Schematic mechanism for the binding of M-CDs to Hg²⁺; (C) The fluorescent intensity ratio I/I₀ of M-CDs with various metal ions (100 μM) vs. Hg²⁺ (100 μM); (D) FL spectra of M-CDs exposed to different concentrations of Hg²⁺ (0-100 μM); (E) The linear fitting of I₀/I vs. the Hg²⁺ concentration (0.008-0.08 μM, R₂ = 0.999).
