Like ninhydrin, amido black is a protein stain. TMB, on the other hand, reacts with the hemoglobin molecule in the blood to produce a colored product. Silver nitrate reacts with salt to produce a dark colored residue. Since salt is often part of the latent print residue, this reaction allows yet another way of development or enhancement of prints. It must follow ninhydrin if sequential enhancements will be applied. If salt is present in the substrate, the entire object will darken. Silver nitrate reacts with light to darken also. In fact, silver nitrate is the principal reactive material in. General Enhancement Methods. General Enhancement Methods Â© Infobase Publishing Â© Infobase Publishing
