Abstract

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

摘要

在这项研究中，采用水热法合成了银铟硫化物/镍钼硫化物（AgInS/NiMoS）纳米结构，并将其修饰在坡缕石（Plg）上，作为抗菌材料的优良载体。研究了制备的 AgInS/NiMoS/Plg 复合材料在光驱动抗菌过程和生物样品中尿酸检测中的性能。结果表明，AgInS/NiMoS/Plg 的抗菌活性最高，最低抑菌浓度约为 0.2-0.3mg/mL。制备的 AgInS/NiMoS/Plg 作为传感器显示出增强的过氧化物酶样活性，可用于检测尿酸。AgInS/NiMoS/Plg 检测尿酸的检出限约为 26.1nM。因此，AgInS/NiMoS/Plg 可用于复杂生物体系中的杀菌过程和传感研究。
