Interactions of gold with DNA and its components constitute an important area of research in the development of potential miniature devices and biotechnology. The interactions between x-Guanine (xG) and gold nanoclusters (Aun) are studied theoretically using density functional theory by Laibin Zhang, Tingqi Ren, Xiuqin Yang, Liuzhu Zhou, and Xiaoming Li on page 2234. The binding modes, interaction strength, and charge-transfer properties of different Aun–xG complexes are investigated. The top of the image shows the gold clusters considered in the work and the x-Guanine is located in the center, on which red dashed circles indicate the possible binding sites. The most stable Aun–xG complexes are shown around x-Guanine.
