A Near-Infrared Luminescent 11-Metal Cd(II)-Nd(III) Nanocluster for the Rapid Excitation Wavelength-Dependent Detection of Rutin.

A near-infrared luminescent Cd(II)-Nd(III) nanocluster 1 (molecular dimensions of 1.0 nm × 2.2 nm × 2.2 nm) was obtained using a Schiff base ligand. It can be used as a sensor for the wavelength-dependent detection of rutin even in the presence of other interference, which can be expressed by the third-order equation I Ex470 nm / I Ex395 nm = A [Rut] 3 + B [Rut] 2 + C [Rut] + D . 1 is used to analyze the Rut concentrations quantitatively in CH 3 CN and fetal calf serum (FCS). For the determination of Rut concentrations in FCS, the ranges of recovery and relative standard deviations are 99.06-104.70% and 2.30-4.15%, respectively.
