英文摘要 | The interactions between neutral Al12X(I (h) ) (X = Al, C, N and P) nanoparticles and DNA nucleobases, namely adenine (A), thymine (T), guanine (G) and cytosine (C), as well as the Watson-Crick base pairs (BPs) AT and GC, were investigated by means of density functional theory computations. The Al12X clusters can tightly bind to DNA bases and BPs to form stable complexes with negative binding Gibbs free energies at room temperature, and considerable charge transfers occur between the bases/BPs and the Al12X clusters. These strong interactions, which are also expected for larger Al nanoparticles, may have potentially adverse impacts on the structure and stability of DNA and thus cause its dysfunction. |
