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.
期刊介绍：
The growing interest and activity in the field of sensor technologies requires a forum for rapid dissemination of important results: Sensor Letters is that forum. Sensor Letters offers scientists, engineers and medical experts timely, peer-reviewed research on sensor science and technology of the highest quality. Sensor Letters publish original rapid communications, full papers and timely state-of-the-art reviews encompassing the fundamental and applied research on sensor science and technology in all fields of science, engineering, and medicine. Highest priority will be given to short communications reporting important new scientific and technological findings.
