A ratiometric fluorescent biosensing platform based on CDs and AuNCs@CGO for patulin detection.

Background: Patulin (PAT) is a mycotoxin, usually found in fruit and their products, that can potentially be harmful to human health. In order to achieve rapid detection of mycotoxins and ensure the safety of food. This study reported a novel ratiometric fluorescent aptasensor for PAT detection.
