Silver chloride/molybdenum disulfide (AgCl/MoS2) nanocomposites were fabricated through a simple chemical precipitation method and used as electrochemical sensors to detect chloramphenicol. The nanocomposites exhibit an excellent sensing property because of the synergistic effect of MoS2 and AgCl. The AgCl/MoS2 nanocomposite with a molar ratio (MoS2:AgCl) of 1:3 has a high sensitivity of 3802 μA mM–1 cm–2, a linear range of 4–531 μM, good selectivity, and an estimated limit of detection of 1.93 μM at a signal-to-noise ratio of 3. This nanocomposite shows accurate measurement results in honey and milk samples and thus can be used for food inspection.
