The frequency of lung cancer in the world is increasing,and there are many ways to treat lung cancer.The use of iron death to treat lung cancer is difficult to be effective.This is mainly because the divalent ferrous ions entering the lungs will be oxidized by a large amount of oxygen in the lungs,so that there are very few ferrous ions that really reach the target cells of lung cancer treatment.How to efficiently transport divalent ferrous ions is a major technical problem,and choosing a good carrier for ferrous ions is an efficient and convenient solution.Minimize the oxidation of ferrous divalent ions during transport.Experiments have found that the use of nanomaterials as carriers can significantly increase the content of free iron in cells.In this project,the ability of nanocarbon carriers to adsorb ferrous ions by studying the stability and structural characteristics of hydrated complexes of graphene oxide and ferrous ions was explored by quantum chemistry.The results show that the structure is the most stable when the spin is 5,which is consistent with the high spin of iron.
