Article Synopsis
  • - Furaltadone (FTD) is a potent veterinary antibiotic that can be harmful to humans as it might cause cancer through the food chain, making it urgent to find a reliable way to detect it at low levels.
  • - Researchers created pamoic acid-capped gold nanoparticles (PA@AuNPs) for detecting FTD, showing that these nanoparticles change in morphology and fluorescence characteristics when interacting with FTD, thus confirming their potential as fluorescent probes.
  • - PA@AuNPs demonstrated high sensitivity and effectiveness in measuring FTD concentrations in water and blood serum, while also being non-toxic to live zebrafish, suggesting their practical application in detecting harmful substances.

Structure, optical absorption, and charge transport properties of dibenzocoronene tetracarboxdiimide (DCDI) based molecules were studied using electronic structure calculations. Based on the optimized neutral, cationic, and anionic geometries the ionized state properties, such as ionization potential, electron affinity, hole extraction potential, electron extraction potentials, and reorganization energy, were calculated. On the basis of the ground state geometry of the studied molecules, the absorption spectra were calculated using the time-dependent density functional theory (TDDFT) method at the PBE0/def-TZVP level of theory.
