Detection of Phenylalanine by Iridium Nanoclusters Using Time-Dependent Density Functional Theory Calculations.

ABSTRACT: Metal nanoclusters have several applications in biological processes, medicine, cancer therapy, catalysis, etc. Iridium (Ir) nanoclusters exhibit excellent detection behavior compared to their bulk material. This work includes a deep insight into the interaction of Ir nanoclusters of four atoms (Ir₄) with amino acids and the analysis of Ir-amino acid (Ir-AAc) complexes. UV-visible spectroscopy of the Ir₄ nanocluster, amino acids, and their complexes was discussed as a way to detect amino acids with the help of the Ir₄ nanocluster. In UV-visible analysis, the UV-visible peak of phenylalanine (Phe) appeared at 204 nm with an excitation energy of 6.02 eV with a 0.0516 oscillator strength. Meanwhile, only in the Ir₄ nanocluster-phenylalanine (Ir-Phe)
