According to different simulations we have done till now I have learned that its all about the working and proportion of the chemicals used to make a solution or coating. If the chemicals used in coating works as they are supposed to it doesn’t if it is a different or same source. Since it does its work from all the reagents used to make the coating the issue of the toxicity or its structure that is important. This can be controlled by varying the concentrations of the reagents used or simply replacing it by same working, different properties defining chemical.
