`
`How does fingerprint powder work? - Scientific American
`
`copper, silicon, titanium and bismuth. Fingerprint powder is applied by brushing it
`
`onto the surface and works by mechanically adhering to the oil and moisture
`
`components of the latent print. When the powder particles adhere to the grease or
`
`moisture forming the latent prints, it causes them to become Visible. The developed
`
`latent prints are then readily observable and able to be collected, preserved and
`
`examined.
