We studied the adsorption attributes of guanine, adenine, thymine, cytosine, and uracil on chair graphane nanosheets based on the density functional theory (DFT) method. The negative formation energy value of chair graphane ensures a stable structure. All the calculations were carried out within the hybrid GGA/B3LYP level of theory.
