Abstract
The absorption studies on serotonin (STO) and platinum metal clusters were investigated. The STO-Pt3 (gas phase) cluster has the maximum adsorption energy, whereas the water medium has the lowest. The gas phase STO-Pt3 absorption energy is -19.18 kcal/mol, while the water solvent is -11.03. The electrophilicity index of all metal-drug systems is greater, indicating that metal clusters make the STO more electrophilic. The cluster's conductivity representation as energy gaps pointed, suggesting it could be a sensor. A more stable gas phase medium has more negative solvation energies than other media types. The metal clusters and molecules interacted substantially in non-covalent interaction studies. ELF and LOL experiments proved electron delocalization energies and RDG confirmed non-covalent interactions. MEP shows the electrophilic and nucleophilic attractions of STO with Pt3 metal clusters. FMO studies show very low energy gap values.
