Conditions for the dispersion of molybdenum disulfide (MoS 2 ) in aqueous solution at concentrations up to 0.12 mg mL −1 using a range of nonionic, biocompatible block copolymers (i.e., Pluronics and Tetronics) are identified. Furthermore, the optimal Pluronic dispersant for MoS 2 is found to be effective for a range of other 2D materials such as molybdenum diselenide, tungsten diselenide, tungsten disulfide, tin selenide, and boron nitride.
