AI Article Synopsis
- AgInS/ZnS quantum dots were created using a solvothermal aqueous method with 3-mercaptopropionic acid as a stabilizer.
- Two strategies were employed for acrylamide sensing: fluorescence quenching by polyacrylamide synthesis under UV light and quenching with 2-naphthalenethiol, which allowed for signal recovery after adding acrylamide.
- The 2-naphthalenethiol method demonstrated better precision and selectivity, achieving acceptable accuracy in detecting acrylamide in fried snack products.
Article Abstract
AgInS/ZnS quantum dots were synthesized solvothermal aqueous phase method using 3-mercaptopropionic acid as the stabilizer. AgInS/ZnS quantum dots were employed for acrylamide sensing under two strategies: (1) quenching of the fluorescence signal by the synthesis of polyacrylamide under UV light and (2) use of 2-naphthalenethiol for quenching of the fluorescence signal of quantum dots followed by a recovery of the signal after the addition of acrylamide. Both methodologies display adequate limits of detection, 15.6 and 4.8 μg L, respectively. However, the 2-napthalenethiol based method exhibited better precision and selectivity compared to the other methodology. Both methodologies were applied for acrylamide detection in fried snack products and acceptable accuracy was obtained using 2-napthalenethiol method.
