“…In addition to biochips and situ photopolymerizable bioglues, radiation is used to develop biochips ( Aly and Elembaby, 2020b ). Gamma radiation, great-energy electrons, and ultraviolet radiation are the most common energy sources used to irradiate biomaterials ( Balashova et al, 2019 ; Aly et al, 2022a ; Elganzory et al, 2022 ). The manuscript aimed to prepare, characterize, and investigate the impact of gamma irradiation on Pd(II), Cu(II), and Cu(I) metal complexes and also an antimicrobial study of these compounds.…”

The main objective of this study is to synthesize and characterize of a new three complexes of Pd (II), Cu (II), and Cu (I) metal ions with novel ligand ((Z)-2-(phenylamino)-N'-(thiophen-2-ylmethylene)acetohydrazide) H2LB. The structural composition of new compounds was assessed using several analytical techniques including FT-IR, 1H-NMR, electronic spectra, powder X-ray diffraction, and thermal behavior analysis. The Gaussian09 program employed the Density Functional Theory (DFT) approach to optimize the geometry of all synthesized compounds, therefore obtaining the most favorable structures and crucial parameters. An investigation was conducted to examine the impact of γ-irradiation on ligands and complexes. Before and after γ-irradiation, the antimicrobial efficiency was investigated for the activity of ligands and their chelates. The Cu(I) complex demonstrated enhanced antibacterial activity after irradiation, as well as other standard medications such as ampicillin and gentamicin. Similarly, the Cu(I) complex exhibited superior activity against antifungal species relative to the standard drug Nystatin. The docking investigation utilized the target location of the topoisomerase enzyme (2xct) chain A.

A new series of Pd (II), Cd (II), and Cu(I) complexes with ((Z)‐2‐(phenylamino)‐N′‐(thiophen‐2‐ylmethylene)acetohydrazide)(H2LB) has been prepared. FT‐IR, 1H‐NMR, electronic spectra, Powder X‐ray, thermal behavior, theoretical methods and DNA interaction of ligand and of Pd (II) and Cu(I) complexes before and after γ‐irradiation are studied. The 1H NMR spectrum of the ligand after γ‐irradiation shows the signals appear at the same position or slightly shift, but the intensity of the bands after γ‐irradiation is higher than before irradiated. X‐ray diffraction (XRD) studies exhibited the samples in nanorange, the crystallite size is 1.94, 4.81 nm for both unirradiated (B1 and B3) and 2.93, 4.72 nm for irradiated (A1 and A3). The thermal stability of the complexes after γ‐irradiation increase than before γ‐irradiation. The possible structures of the metal complexes have been computed using the molecular mechanic calculations UFF using quantum chemical software by Gaussian 09 W program. The calculations are performed with DFT/B3LYP/LANL2DZ to obtain the optimized molecular geometry. Some important quantum chemical descriptors of the metal complexes were calculated such as HOMO, LUMO, and energy gap. Metal complexes before and after irradiation in the absence and presence of increasing amounts of CT‐DNA exhibit that the absorption intensities decrease with increasing the concentration of DNA.
