In this work, a colorimetric aptamer-based method for detection of cadmium using gold nanoparticles modified MoS2 nanocomposites as enzyme mimic is established. In short, biotinylated Cd2+ aptamers are immobilized by biotin-avidin binding on the bottoms of the microplate, the complementary strands of Cd2+ aptamers are connected to the Au-MoS2 nanocomposites which have the function of enhanced peroxidase-like activity. The csDNA-Au-MoS2 signal probe and target Cd2+ compete for binding Cd2+ aptamer, the color chan
