AbstractA novel sensing colloidal nanoprobe and indicator paper based on fluorescent carboxymethyl chitosan grafted poly(p-dioxanone) (CMCs-g-PPDO) copolymer nanomicelles which encapsulate hydrophobic conjugated polymer-poly(9,9-dioctylfluorene) (PFO) were developed for the fast and sensitive determination of banned food dye Sudan I. The PFO/CMCs-g-PPDO colloidal solution can selectively detect Sudan I in aqueous media among commonly appearing natural pigments: β-carotene, Monascorubrin and Lycopene. The sensing constant (K) for the PFO/CMCs-g-PPDO aqueous solution toward Sudan I was 1.74 × 10 M, which was over 400 times larger than that of single PFO in toluene solution, due to the maximized interaction between the sensing material and the analyte within the chitosan-based nanomicelles. The fluorescent indicator paper functionalized with PFO/CMCs-g-PPDO also showed outstanding selectivity for Sudan I. By using this flexible and portable indicator paper, Sudan I dye could be immediately and visually distinguished from natural pigments. This material could be used for real-time and on-site food safety testing. © 2014 the Partner Organisations.
