“…The fabrication process of these devices has been covered elsewhere [16,17,18,19], and hence will not be detailed in this review. As polymer science and micro/nanofabrication technologies have been advancing, a wide range of LOC devices have emerged for different applications including diagnostics, proteomics, metabolomics, genomics [4,14,20], (bio)analytical chemistry [21,22,23,24], organic chemistry [25,26], environmental monitoring [27,28], fuel cells [29], biodefence [30], as well as the monitoring of food safety and quality [31,32,33].…”
