There is intense interest of layered materials such as molybdenum disulfide-based two-dimensional nanosheets for various applications including electrical and optical devices. Here we have studied the dissolution behaviors of molybdenum disulfide in aqueous solution with the assistance of dsDNA under sonication. Various conditions including dsDNA concentrations, sonication time, buffer constituents, and different pH levels have been examined for preparing molybdenum disulfide aqueous suspensions. The obtained suspensions show characteristic optical absorption features of molybdenum disulfide monolayers. Further discussion will focus on the optical properties of the molybdenum disulfide suspensions at different pH levels.
