Techniques/chemicals for lifting fingerprints

Let’s say that a house gets broken into. Well the perpetrator will leave prints everywhere, sometimes without knowing. He may leave prints on porous or non-porous surfaces. Examples of porous surfaces would be paper, unfinished wood, or cardboard. Non-porous surfaces could be glass, plastic, or a metal. Since we said that the house was broke into, there are likely to be fingerprints on the door knob, which in this case is going to be metal. For a porous surface, like a metal, you should most likely use a powder. A metallic, black, or white colored powder, is best depending on which powder would contrast the most with the surface containing the fingerprint. If the crime is a kidnapping, then there might be a note. The note, written on paper, would be an example of a porous surface. There are two ways you can lift prints from a porous surface. One being use a chemical or chemical solution. The most common chemicals are iodine, ninhydren, and silver nitrate. The other way would be to use super glue fumes in an airtight container.
