Abstract

This article describes the development of lignocellulose-based analytical  devices (LADs) for rapid bioanalysis in low-resource settings. lignocellulose-based analytical devices are constructed using either a single lignocellulose or a hybrid design consisting of multiple types of lignocellulose. lignocellulose-based analytical devices are simple, low-cost, easy to use, provide rapid response, and do not require external instrumentation during operation. Here, we demonstrate the implementation of lignocellulose-based analytical devices for food and water safety (i.e., nitrite assay in hot-pot soup, bacterial  detection in water, and resazurin assay in milk) and urinalysis (i.e., nitrite, urobilinogen, and pH assays in human urine). Notably, we created a unique approach using simple chemicals to achieve sensitivity similar to that of commercially available immunochromatographic strips that is low-cost, and provides on-site, rapid detection, for instance, of Eschericia coli (E. coli) in water.
