A new cross double point discharge (CrossPD) microplasma was designed as an excitation source to construct a miniaturized optical emission spectrometer with hydride generation (HG) for sample introduction. The CrossPD...
A novel “on–off” fluorescent probe for the determination of ammonia nitrogen has been synthesized. URO can replace PAL into the cavity of CB[7] to form a stable inclusion complex, eventually forming the fluorescence quenching system of URO@CB[7].
A direct competitive nanozyme-linked immunosorbent assay (dcNLISA) based on MnO2 nanosheets (MnO2 NSs) as a nanozyme label was developed for the highly sensitive determination of fumonisin B1 (FB1). The MnO2...
