Latex-Based Paper Devices with Super Solvent Resistance for On-the-Spot Detection of Metanil Yellow in Food Samples

Abstract The following paper presents a construct for paper-based device which utilizes latex as the hydrophobic material fabrication of its barrier, was deposited onto cellulose surface either by free-hand or stenciled drawing. This method demands least amount expertise and time from use, enabling simple rapid experience. Several properties were characterized, such hydro head penetration rate, with aim assessing robustness stability. presented barriers fabricated using this approach have barrier width 4 mm, coating thickness 208 µm, hydrophilic resolution 446.5 µm. modality boasts an excellent solvent resistance regard to barrier. These devices employed on-the-spot detection Metanil Yellow, banned food adulterant often used in curcumin pigeon peas, within successful limits (LOD) 0.5% (w/w) 0.25% (w/w), respectively. results indicate great potential has numerous applications other closely related domains, diagnostics sensing, signalling capacity become commonplace both industrial domestic settings.
