Time‐gated emission spectra (delay time: 100 ns) of Ru‐NBD (10 × 10⁻⁶ m) in the absence and presence of different concentrations of GSH (0–15 × 10⁻⁶ m) A), Cys (0–15 × 10⁻⁶ m) B) and Hcy (0–15 × 10⁻⁶ m) C) in 50 × 10⁻³ m Tris‐HCl buffer (pH 7.4). Linear correlation of emission intensity at 610 nm against the concentration of D) GSH, E) Cys, and F) Hcy. (λ _ex = 450 nm)
