Abstract
N, N’-di (L-glutamic amine)-perylene-3,4,9,10-tetracarboxylic diimide (GAPDI) functionalized Sb2S3 nanocomposites (GAPDI-Sb2S3) were fabricated using a hydrothermal method and characterized. GAPDI-Sb2S3 nanocomposites can catalyze the oxidation of 3,3′,5,5′- tetramethyl benzidine (TMB) by H2O2. The experimental conditions including pH and temperature were optimized. GAPDI-Sb2S3 nanocomposites showed a strong affinity for TMB substrates, and their catalytic activity followed the Michaelis–Menten kinetics. The experimental results showed that GAPDI-Sb2S3 nanocomposites exhibited a low detection limit (LOD = 0.39 μM) and high sensitivity for H2O2 detection and showed good response to glucose detection with a LOD of 0.42 μM over arrange of 2–10 μM. These findings suggest broad application prospects in the fields of environmental chemistry, biotechnology, and biomedicine.
