Recent advances of conjugated polymer (CP) nanocomposite-based chemical sensors and their applications in food spoilage detection: A comprehensive review

Functional Polymers and Polymer–Dye Composites for Food Sensing

“…[ 75–78 ] This feature is related to the ability of π‐conjugated polymers to serve as a highly efficient transport medium for the electronic excited states. [ 28,79–81 ] The absorption and fluorescence properties of π‐CP can be easily affected by the intramolecular conformation and intermolecular aggregation, chemical environment, etc. Through direct incorporation of receptors into the π‐CP backbone, the relevant change of absorption or fluorescence of π‐CP after interaction with analytes provides a sensing principle to the design of the π‐CP‐based sensor.…”

Nanotechnology in the development of food packaging: A supertechnology that successfully addresses the current challenges of packaging and friendly to the environment

“…Actualmente, la industria alimentaria exige metodologías analíticas rápidas para evaluación de deterioro de los alimentos con el propósito de retrasar la senescencia del producto. Según un estudio realizado por Pavase et al (2018), más de 1.3 millones de toneladas por año de alimentos envasados para el consumo humano son desperdiciados debido al deterioro, por lo que muchos investigadores se han motivado enfrentar estas deficiencias por la realización del campo emergente de la detección basados en la nanotecnología han surgido como nanosensores. Los nanosensores son herramientas multiuso muy simple, rentable y de consumo que ilustran un alcance potencial de sistemas que afirman la calidad de diversos productos perecederos tales como mariscos, carne de cerdo, carne de res, cordero y pollo para su viabilidad comercial.…”

Probabilistic topic modelling in food spoilage analysis: A case study with Atlantic salmon (Salmo salar)

“…In the food and nutrition sector, this global trend has had a major impact on the development of foodomics (Miguel et al, 2012), a novel interdisciplinary field where metabolomicsthe study of low molecular weight (<1500 Da) molecules associated with biological samples (Castro-Puyana et al, 2017;Pinu, 2016) has already been used for addressing various questions related to food quality and safety (Böhme et al, 2019;Klampfl, 2018;Mancano et al, 2018;Martinović et al, 2018;Xu, 2017). In particular, the latest advances in the analysis of spoilage-indicating volatile organic compounds (VOCs) have greatly benefitted both scientific knowledge (Dong et al, 2019;Odeyemi et al, 2018;Wang et al, 2016) and technology development (Ghasemi-Varnamkhasti et al, 2018;Pavase et al, 2018;Poghossian et al, 2019).…”
