| Outline of Research at the Start |
The main purpose in this research is atomic-level manipulation of metal clusters. The manipulation includes number, composition, structure and sequence of the atoms in a cluster. 3. In order to achieve this, a novel and original cyclic atomic electrodeposition process allowing deposition of metal
atoms one-by-one at a specific location has been developed to allow preparation of the atomic-level metal clusters. In addition, evaluating and clarifying the atomic-level metal clusters’ extraordinary properties, especially the even-odd effect, is another purpose in my research.

| Outline of Final Research Achievements |
The objective of this 3-year project is to develop novel catalytic materials for biosensors through the decoration of atomic-level metal clusters onto conjugated polymers using a unique cyclic atomic electrodeposition technique. The accomplishments include 7 peer-reviewed papers, presentations at 12 international conferences, and 4 domestic conferences. Of the 7 published papers, 6 are open access publications. Additionally, one of the conference presentations was delivered as an invited talk at an international conference.
The research commenced with the optimization of the original cyclic atomic electrodeposition technique, followed by the preparation and study of atomic pure metal clusters (such as Au, Pd, and Pt) on polyaniline. In the last fiscal year, the research progressed to the deposition of atomic Pd-Au alloy clusters, with the results already published in a peer-reviewed scientific paper.

| Academic Significance and Societal Importance of the Research Achievements |
Catalytic materials are expected to be a key solution for achieving the Sustainable Development Goals (SDGs). It is anticipated that performance will be enhanced through size reduction. Therefore, the atomic-level catalysts developed in this project will make a significant contribution to the SDGs.
