英文摘要 | Food safety is a constant concern for humans. Besides adulteration and contamination, another major threat comes from the spontaneous spoilage of perishable products, which is basically inevitable and highly dependent on the temperature history during the custody chain. For advanced quality control and assessment, time-temperature indicators (TTIs) can be deployed to document the temperature history. However, the use of TTIs is currently limited by either relatively high cost or poor programmability. Here we describe a general, kinetically programmable, and cost-efficient TTI protocol constructed from plasmonic nanocrystals. We present proof-of-principle demonstrations that our III can be specifically tailored and thus used to track perishables, dynamically mimic the deteriorative processes therein, and Indicate product quality through sharp-contrast multicolor changes. The flexible programmability of our TTI, combined with Its substantially low cost and low toxicity, promises a general applicability to each single packaged item of a plethora of perishable products.; Chemistry, Multidisciplinary; Chemistry, Physical; Nanoscience & Nanotechnology; Materials Science, Multidisciplinary; SCI(E); EI; PubMed; 12; ARTICLE; 5; 4561-4568; 7 |
