Abstract

In this work, microwires of gold nanoparticles (Au NPs) were grown using the fungus Aspergillus niger as a biological template. Au NPs were synthesized through the reduction of chloroauric acid using monosodium glutamate (MSG) in an aqueous media. The MSG here, served as a nutritional trigger behind the self-organization of Au NPs on Aspergillus niger apart from being the reducing as well as stabilizing agent. The fungal hyphae coated with gold nanoparticles were spread over the glass slide. The ZnO/ZnS core/shell nanostructures were deposited in a 2 mm gap of gold microwires’ spread. Uric acid sensing behavior of these ZnO/ZnS core/shell nanostructures were studied using the gold microwires as electrode.

生物启发金线上用于尿酸传感的ZnO/ZnS核/壳纳米结构

在这项工作中，利用真菌黑曲霉作为生物模板，培养了金纳米颗粒(Au NPs)的微丝。采用味精在水介质中还原氯金酸合成金纳米粒子。这里的味精除了作为还原和稳定剂之外，还作为黑曲霉Au NPs自组织背后的营养触发器。用金纳米颗粒包被的真菌菌丝铺在玻片上。ZnO/ZnS核/壳纳米结构沉积在2 mm的金微线铺展间隙中。以金微细线为电极，研究了这些ZnO/ZnS核/壳纳米结构对尿酸的传感行为。
