Transition metal sulfides (TMS) have been receiving specific attention due to their excellent physiochemical properties and electrochemical activity. In this article, we demonstrate the synthesis of sea-urchin-like Bi2S3 combined with MoS2 hierarchical nanoflowers via a hydrothermal route for sensing Flufenamic acid (FMA). FMA is one non-steroidal anti-inflammatory drugs (NSAIDs) which endangers human health. The Bi2S3/MoS2 composite's formation was confirmed by various characterizations microscopic spectroscopic techniques. synergistic effect between two improves electron transport enables more active sites. Under optimal conditions, resultant nanocomposite exhibits high sensitivity value (0.44 ​μA ​μM−1 ​cm−2), reasonable limit detection (0.009 ​μM), broad linear range (0.01 – 453 ​μM). Furthermore, in biological samples achieved good reliability decent recovery.
