Abstract: The present disclosure provides a method and a platform for enhancing detection activity of an interaction between a spike protein receptor binding domain of coronavirus from a specimen and a human angiotensin-converting enzyme II. The method and the platform of the present disclosure use a cleavable luciferase as a report test for the combination of the spike protein receptor binding domain of coronavirus (such as novel coronavirus) and angiotensin-converting enzyme II. Screening is carried out at the cellular level. The strength of the drug's influence on the interaction between the two molecules can be judged by the strength of the luminescence signal. The detection time can be completed within 20 minutes.

Abstract: The invention prepares FeNiCrTi/NiAl-A12O3 nanocomposite materials by a method of in situ synthesis by thermite reaction with sol-gel. The nanocomposite material has high intensity at high temperature, high tenacity at room temperature, good oxidation resistance and good resistance to thermal corrosion. The method of the invention comprises: igniting thermite mixture to produce a high temperature melt and putting the high temperature melt into a fast-cooling mold, thereby obtaining the FeNiCrTi/NiAl—Al2O3 nanocomposite material. The thermite mixture contains Fe2O3, NiO, Cr2O3, CrO3, Al and TiO2 gel. The composite material is featured by small size of grains.
