摘要

Food contamination by toxic mycotoxins not only causes a considerable loss in economy, but importantly poses a huge threat to human health through accidental ingestion. Hence, it is an ongoing and imperative need to develop a convenient, cost-effective method for the detection of the mycotoxin-infected agricultural commodities. To this end, we herein fabricated a novel metal organic framework-derived composite material that displays a strong solid-state emission in the visible region, by attaching a frequently used fluorescent label, fluorescein isothiocyanate (FITC), via guest adsorption. Significantly, owing to the inherent pH-responsive conformational changes of FITC, the resulting composite material provides, to the best of our knowledge, the first example of the sensitive and selective fluorescence sensing toward 3-nitropropionic acid, which, as a major naturally occurring mycotoxin in moldy sugarcane, has been closely linked to poisoning episodes in human beings and animals.
