Forensic spray using jellyfish protein could speed up fingerprint detection

Dyes based on the fluorescent proteins are also water-soluble and low-toxicity so could replace solvents

Scientists have developed a forensic spray using a protein found in jellyfish that shows up fingerprints in just 10 seconds.

They say that the dye spray could make forensic investigations quicker and more effective. It is also water-soluble and has low toxicity. Traditional forensic methods either use toxic powders that can harm DNA evidence or petrochemical solvents that are bad for the environment, the sale of which is increasingly restricted.
