• We have studied 6-thioguanine, a substituent of deoxyribonucleic acid (DNA) bases, adsorbed on a Au(111) surface by scanning tunneling microscopy (STM) under ambient condition in air. Observation of the STM image of the molecule suggests that thioguanine is bound to the Au substrate through the Au-S bond formation described in STM studies of alkanethiolate molecules. Our STM images obtained under ambient condition are much more similar to those of a planar two-dimensional hydrogen-bonded array of guanine molecules on a MoS_2 substrate rather than those of a disordered array of guanine on a Au substrate in solution.
