Aggregation-induced emission carbon dots-based dual-mode sensor for smartphone-assisted rapid detection of putrescine in shrimp.
Accurate on-site detection of food spoilage indicators constitutes a fundamental requirement for evaluating food freshness and ensuring safety. In this work, a dual-mode sensor (CDs/AuNCs) integrating carbon dots and gold nanoclusters was reported, which enabled the rapid detection of putrescine within 20 s. Interactio...
