A novel electrochemiluminescence immunosensing strategy fabricated by Co(OH) two-dimensional nanosheets and Ru@SiO-Au NPs for the highly sensitive detection of enrofloxacin.

In this work, a novel sensitive electrochemiluminescence immunosensor based on Ru@SiO-Au NPs and Co(OH) two-dimensional nanosheets (2D Co(OH)) is constructed for the detection of enrofloxacin (ENR). Ruthenium bipyridine silica spheres and modified gold nanoparticles were synthesized as immune probe materials, which were combined with ENR antibodies (Abs) to form the immune probe part. 2D Co(OH) with a large specific surface area and good catalytic effect was firstly used as an immune substrate material, and at the same time, it was conjugated with the coating antigen (Ae) of ENR to form an immune substrate.

Hydrogen-Atom Tunneling in Metaphosphorous Acid.

Metaphosphorous acid (HOPO), a key intermediate in phosphorus chemistry, has been generated in syn- and anti-conformations in the gas phase by high-vacuum flash pyrolysis (HVFP) of a molecular precursor ethoxyphosphinidene oxide (EtOPO→C H +HOPO) at ca. 1000 K and subsequently trapped in an N -matrix at 2.8 K.
