Revolutionary Jellyfish Protein-Based Spray Rapidly Visualizes Fingerprints

A groundbreaking spray developed by UK and Chinese scientists enables law enforcement to detect fingerprints in seconds, enhancing forensic investigations.

• A UK-Chinese team has created a biocompatible, fluorescent spray derived from jellyfish protein that visualizes fingerprints in just 10 seconds.
• The non-toxic, water-soluble spray offers a safer, faster, and more environmentally friendly alternative to traditional fingerprint detection methods.
• The spray, available in two colors, binds selectively to fingerprint molecules, emitting a fluorescent glow visible under blue light.
• The technology, which does not interfere with DNA analysis, can be used on a variety of surfaces, including rough textures like brick.
• Scientists are collaborating with companies to commercialize the dyes, with ongoing research to expand the range of available colors.
