Thermodynamic Feasibility

A rapid, facile, reproducible and green method for synthesizing SnSe nanosheets in aqueous media is reported. Cyclic voltammetry studies indicate better thermodynamic feasibility for reducing SnSe, while the nanomaterial is nontoxic up to a 100 μM concentration in CHO cells.
