UK security firm RedWeb Security has developed an "i-powder" that sticks to an intruder, staining him/her with a "unique DNA code" of the powder's owner. The result is irrefutable proof linking a criminal to the scene of the crime.
The powder, suspended in a red dye, cannot be washed off for several weeks. I-powder is currently being marketed to retail establishments; in cases in the UK where it has been presented as evidence, RedWeb claims that it has led to a 100% convinction rate. A version for home security systems is presently in the works.
