A superhydrophobic modified film and modification method, and a triboelectric nanogenerator (TENG) composed thereof and a preparation method are disclosed. A polyethylene (PE) film is etched and deposited with an inductively coupled plasma (ICP) etcher in sequence. A nano-textured structure is formed on an upper surface of the PE film and a fluorocarbon layer is further deposited for modification. An upper electrode of the film is constructed by sticking a piece of ultra-thin copper tape on a superhydrophobic surface of the superhydrophobic modified film, and a lower electrode of the film is constructed by spin-coating a conductive polymer on a lower surface of the film after Oplasma treatment. Thus, the TENG with high output and a double-electrode working mode based on the superhydrophobic modified greenhouse film is constructed. According to the modification method, the nano-textured structure is constructed on the surface of the film.

The present invention describes a test kit for the detection of fat-soluble vitamins in serum using a method based on high performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS). The internal standard (IS) solution included in the kit is based on methanol, acetonitrile and isopropyl alcohol solvents. Ammonium acetate is added to the IS solution to make it more stable and last for longer storage time. The application of this kit can significantly improve the recovery and detection sensitivity of vitamins A, E, K1 and K2 in serum without additional sample enrichment, make sample preparation process simpler and more efficient, keep processed samples stable for longer time, and lower the overall cost for more accurate and repeatable test results.
