Abstract
- Over use of lincomycin (LIN) as antibiotic in animals can lead to multiple harmful impacts to public health, thus detection of LIN at trace level in milk and chicken sample matrixes is vital. In this work, Zinc phthalocyanine nanoparticles sensitized MoS 2 (ZnPc/MoS 2) was firstly developed as a novel photocathode material combined with nitrogen-doped graphene-loaded TiO 2 nanoparticles (TiO 2 /NG) as photoanode material to construct a dual-photoelectrode photofuel cell (PFC). The as-prepared membrane/mediator-free PFC achieved excellent output performance that the maximum power density (P max) reached 11.83 μW cm−2. Specific aptamers are adopted as LIN recognition elements, the as-proposed self-powered aptasensor for LIN exhibited a linear scope in 10−11 –10−5 mol L−1 along with a low detection limit (3S/N) of 3.33 pmol L−1. Consequently, such high-power density dual-photoelectrode PFC aptasensor may be a reassuring candidate electrochemical sensor for the detection of trace contamination in food samples. [Display omitted] • Zinc phthalocyanine sensitized MoS 2 was developed as a novel photocathode material. • The maximum power density reached 11.83 μW cm−2 • A dual-photoelectrode PFC lincomycin aptasensor was successfully established. • This aptasensor can be applied to detect lincomycin in milk and chicken.
