Enantioselective determination of S-ornidazole by using carbon paste electrode modified with boron-embedded conductive copolymer-polysiloxane-based molecularly imprinted hybrid film

•An innovative B-MIHF-based sensor was fabricated for the sensing of S-ONZ.•The coordinate interaction endows the sensor with excellent enantioselectivety.•Differential pulse voltammetry for the quantification of S-ONZ at trace level.•B-MIHF: boron-embedded molecularly imprinted hybrid film.
