要旨

Cisplatin is a well known anti-cancer drug and considered as essential by the World Health Organization. However, cisplatin features side effects during medical treatments due to its lack of selectivity resulting in the indiscriminate death of cells including healthy cells. To solve this issue, it is mandatory to improve its delivery towards affected organs or tissues. The well known bio-compatibility of gold clusters encouraged us to study the interaction between cisplatin molecules and the Au18(SR)14 cluster (named Au18) and our DFT calculations have provided insight into this aspect. Calculated adsorption energy values of the cisplatinn/Au18 complexes are within the 0.5–3.6 eV range, which attests to their unique interaction. In addition, their calculated optical absorption (UV-vis) and circular dichroism (CD) spectra display distinct peaks in such a manner that UV/CD spectra can be used as fingerprints by experimentalists.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
