Gold-coated ZnO nanostructures on no-core optical fiber for ammonia detection in food spoilage applications

Abstract A selective and cost-effective optical fiber sensor for detecting ammonia gas, a key byproduct of food spoilage, was developed using a no-core fiber (NCF) structure. The optical fiber was coated with a zinc oxide (ZnO) thin film decorated with gold nanoparticles (AuNPs) to enhance sensitivi...
