Synergistic activities of silver indium sulfide/nickel molybdenum sulfide nanostructures anchored on clay mineral for light-driven bactericidal performance, and detection of uric acid from gout patient serum

Abstract

In this study, the hydrothermal method was used to synthesis of silver indium sulfide/nickel molybdenum sulfide (AgInS₂/NiMoS₄) nanostructure and decorated on Palygorskite (Plg) as an excellent carrier of antibacterial materials. The performance of the prepared AgInS₂/NiMoS₄/Plg composites was investigated for light-driven antibacterial process and detection of uric acid from biological samples. The result shows the highest antibacterial activity of the AgInS₂/NiMoS₄/Plg with the minimum inhibitory concentrations about 0.2-0.3 mg/mL. The prepared AgInS₂/NiMoS₄/Plg as sensor depicted enhanced peroxidase-like activity for detection of acid uric. The detection limit of acid uric by AgInS₂/NiMoS₄/Plg was about 26.1 nM. Therefore, the AgInS₂/NiMoS₄/Plg can be developed in the bactericidal process and sensing in complex biological systems.
