Abstract: The present disclosure discloses a process for evaluating a corrosion inhibitor based on a high-throughput corrosion chip. In the present disclosure, a high-throughput corrosion chip is first prepared by using a chip spotter, and only a corrosion inhibitor and a corrosive substance need to be spotted on a metal sample to quickly, efficiently, and accurately evaluate performance of a corrosion inhibitor formulation, to meet corrosion test conditions such as different substances, different concentrations, and different corrosion duration; and then a corrosion degree of each measurement point in the high-throughput corrosion chip is identified and quantified by using a laser scanning confocal microscope. The high-throughput corrosion chip prepared by using the foregoing method can bear 10-1000 measurement points, and these measurement points can reflect corrosion effects of different inhibitor formulations in different corrosion duration.

Abstract: Disclosed in the present invention are a gene interference vector- and iron nanoparticle-based composition for killing cancer cells, and the use thereof. The composition comprises a gene interference vector and iron nanoparticles, wherein the gene interference vector is a CRISPR/Cas13a expression vector or microRNA expression vector controlled by a cancer cell specific promoter DMP, with the Cas13a-gRNA or microRNA expressed by the vector being able to inhibit, in a targeted manner, intracellular iron metabolism and the expression of reactive oxygen related genes, and the iron nanoparticles can be degraded after entering cells to produce iron ions and to increase the reactive oxygen level. The composition comprising the gene interference vector and the iron nanoparticles of the present invention can be used for preparing a new reagent for treating cancers.
