It is generally assumed that MIP selectivity depends mainly on compatibility between the analyte and polymer being used. Accordingly, less research has concentrated on applying imprinting techniques to modify the polymeric material. Where applied, imprinting has traditionally been carried out with one or two small target molecules simply mixed with or loaded on polymers. In this study, we employed a novel alternative protocol incorporating dengue virus particles to assist imprinting of DNT. The binding sites and affinity of DNT with dengue surface protein were simulated for enhancing MIP selectivity. Composite MIP sensors were produced and tested to detect explosive molecules including DNT, TNT, and PETN in aqueous solution. Interestingly, the sensor fabricated with DNT template and dengue virus co-imprinting demonstrated improved TNT selectivity as compared to the other MIP sensors. The detection limit of these sensors approached 0.3 ppt.Mahidol UniversityEngineeringMaterials SciencePhysics and AstronomyArticleSCOPUS10.1016/j.matlet.2020.129201
