“…In luminescence sensors the emitted fluorescence, phosphorescence or chemiluminescence signals are measured after the analyte is immobilized in a suitable solid support, giving origin to the expression solid-phase luminescence (SPL) or to its equivalent solid-matrix luminescence (SML). Under certain conditions, these analytical signals can be related to the concentration of analyte in the sample (Ibañez & Escandar, 2011).…”

Background Intelligent packaging is the newest technology within the food packaging field. Even though this technology is still growing and not fully commercially viable, it has enormous potential to improve the safety, quality, and traceability of food products, as well as its convenience for consumers. Scope and Approach This paper first describes both the technical aspects and commercial applications of the most representative intelligent technologies-indicators, data carriers, and sensors-with special focus on systems and devices that are directly integrated into the package. Secondly, to provide useful guidelines for future research in the field, the paper discusses some important aspects that still hinder the full exploitation of intelligent technology within the food packaging industry.

“…2,3 Conventional pesticide analysis mainly relies on UV-HPLC, 4,5 GC-MS, 6 fluorescent and chemiluminescent assays. 7,8 However, these methods require bulky instruments together with fully equipped laboratory infrastructure and well-trained operators. Therefore, it is important to develop fast and accurate screening methods to enable on-site detection of pesticides.…”

Flow Control-based 3D μPADs for Organophosphate Pesticide Detection

et al. 2018

Flow control-based paper devices have recently shown great potential for point-of-need analysis, since they allow for the easy operation of multi-step assays by minimizing user operation. In this work, a wax printing method was evaluated as a means to control liquid flow in 3D microfluidic paper-based analytical devices (μPADs). The resulting flow controlbased 3D μPADs were applied to determine paraoxon-ethyl as a typical organophosphate pesticide model system. The analytical procedure is as simple as applying a 200-μL sample solution, resulting in reproducible (relative standard deviation of colorimetric signals from 6 independently fabricated devices, 2.63%) colorimetric signals within 1 h of the assay time with the limit of detection (LOD) reaching 25.0 μg/L. Finally, results obtained for pesticide-spiked water samples analyzed by flow control-based 3D μPADs showed good agreement with those from a conventional HPLC analysis with UV detection.

“…14,15 Due to the recaptured attention around the topic, in the past two decades the development of chemical sensors for environmental analysis based on uorescence signals was consolidated as a dynamic area within the sensor eld. 16 From a quite general view, a chemical sensor is frequently dened as a device that interacts chemically with an analyte, transforming either qualitative or quantitative chemical information into an analytically useful signal. 17 More specically, it is a miniaturized device able to provide real-time information about the presence of specic analyte in a sample.…”
