"Rapid Fingerprint Detection with Jellyfish Protein Spray"

Scientists have developed a forensic spray using a protein found in jellyfish that can reveal fingerprints in just 10 seconds, making forensic investigations quicker and more effective. The water-soluble and low-toxicity dye spray, based on a fluorescent compound called green fluorescent protein (GFP), is biologically compatible and does not interfere with DNA analysis. The spray comes in two colors, binds to chemicals in sweat and oils, and emits a fluorescent glow under blue light. This innovation offers a safer, more sustainable, and faster alternative to traditional fingerprint detection methods, and the team aims to make the forensic dyes commercially available.
