Song Yongbo, a young teacher in the School of Biomedical Engineering of Anhui Medical University, and his collaborators have made important progress in the research of metal nanoclusters, realized the spiral assembly of atomically precise nanoclusters, and analyzed its formation mechanism at the atomic level
For a long time, using the special properties of deoxyribonucleic acid, inorganic nanoparticles can construct various helical assemblies by modifying their surfaces
Song Yongbo and his collaborators obtained Au29 clusters with heterodimeric structure through precise control of the nanocluster structure
In the double helix structure, they observed two chiral enantiomers of Au29, and each enantiomer has four different surface motif structures, two inherited from Au28, and the other two inherited from Au30
Atomically precise nanoclusters can be used to clarify problems that conventional nanoparticles cannot explain so far, so that everyone can clearly "see" what is on the surface of nanoparticles, how the interaction between nanoparticles occurs, and explore the principles of nanoparticle assembly And function control
