A new bullet-tagging technology being developed in the UK could give forensic teams a robust new tool in the fight against gun crime.
The breakthrough has been achieved by a multidisciplinary team from Brighton, Brunel, Cranfield, Surrey and York universities, with funding from the Engineering and Physical Sciences Research Council (EPSRC). Project partners include the Forensic Science Service, BAE Systems and coatings manufacturer Andura.
The tags, which measure 30 microns in diameter, are applied to gun cartridges by being embedded in cartridge coatings made from polylactic acid, sucrose ester and tetrahydrofuran. They then attach themselves to the hands or gloves of anyone handling the cartridge and are said to be very difficult to wash off.
A portion of the tag remains on the cartridge even after it has been fired, which could make it possible to establish a definitive forensic link between a cartridge fired during a crime and whoever handled it.
The current success rates for DNA profiling using evidence from gun cartridges are only around 10 per cent. To date it has been extremely hard to establish such a link because of the difficulty in retrieving fingerprints or significant amounts of DNA from cartridge surfaces.
‘The tags primarily consist of naturally occurring pollen, a substance that evolution has provided with extraordinary adhesive properties,' said Prof Paul Sermon from Surrey University, who led the research.
He added: ‘It has been given a unique chemical signature by coating it with titanium oxide, zirconia, silica or a mixture of other oxides.
'The precise composition of this coating can be varied subtly from one batch of cartridges to another, enabling a firm connection to be made between a particular fired cartridge and its user.’
The team has also developed a method of trapping forensically useful amounts of DNA on gun cartridges. It involves increasing the abrasive character of the cartridge case with micro-patterned pyramid textures, or adding an abrasive grit, held in place by a thin layer of resin, to the cartridge base.
This rough surface is able to retain dead skin cells from a thumb as it loads a cartridge into a firearm.
The technology has been designed to avoid damage to the DNA captured that is caused by temperatures generated as the gun is fired, when heat is rapidly transferred from the burning propellant into the cartridge case and when copper is extracted from the cartridge case by lactic acid in sweat.
The tag and DNA-capture technologies could potentially be available for use within as little as 12 months. There may also be scope to apply them in other fields, such as knife crime, in future.
‘We’re currently focusing on understanding the precise requirements of the police and cartridge manufacturers,’ said Prof Sermon. ‘But our work clearly could make a valuable contribution not only to solving gun crime but also to deterring criminals from resorting to the use of firearms in the first place.’
I have a huge supply of lead and molds.......
Just something to raise the cost of ammunition. I’m sure there’s a dozen ways of defeating this if someone wants too.
It would probably also lead to increased use of revolvers by criminals, so they don’t leave the casing behind.
Final note - i thought they banned guns in England. That would mean there is no more gun crime, right?
BAE is a huge defense contractor in the US. No doubt they have LE contracts, too.
The UK is far worse than the usa for not punishing criminals. The only one's this would hurt are the honest gun owners. “Gun Control is not about guns or crime control.”
“Final note - i thought they banned guns in England. That would mean there is no more gun crime, right?”
They’re just such a nice bunch of fart smellers, I mean Smart Fellers, that they want to help US with OUR “problems”.
OR... “Gun Control is about CONTROL, but it is not about guns”.
Can I point out that making a cartridge case abrasive enough to remove skin cells will make it a wee bit difficult to eject, let alone draw and form? But, when did the Brit police show any smarts, since 1950?
“A new bullet-tagging technology being developed in the UK could give forensic teams a robust new tool in the fight against gun crime.”
Translation:
A new impediment to legitimate gun owners has been devised by hoplophobic researchers in the anti-gun Kingdom of Britain.
They’ll want to tag those too.

That's the point.
It's difficult to argue with that. If I may offer another solution to the problem.
Perhaps, we could pass another law. We could simply request the criminal leave a note at the scene of the crime just like when you park to close to my new car and accidentally put another ding in the side of the door.
Simple, cost effective and except for the criminal should not offend anyone.
It will take me ages to get through my supply of bullets before I have to resort to that... :o)
Surgical gloves and throw them away later. Don’t want to do that? Then load your own and make your own bullets, lead and molds are common. In a country where owning a gun is against the law but still relatively easy to obtain why do they think someone couldn’t get ammo that was free of this stuff one way or another? This will catch zero criminals in my opinion and is just another idiotic sop to the gun grabbers.
The coatings are on the bullets themselves. If you touch the bullet, a tiny bit of skin cells well be left behind on it. As long as it doesn’t cost more (yea, right) or affect accuracy, or cause abnormal bore wear, who cares?
While it may be difficult to remove this stuff from a box of bullets, give me half an hour and I'll find a chemical that will take it off a knife like water off a duck's back.
‘The coatings are on the bullets themselves. If you touch the bullet, a tiny bit of skin cells well be left behind on it. As long as it doesn’t cost more (yea, right) or affect accuracy, or cause abnormal bore wear, who cares?”
Who cares? Its a stupid idea whose sole purpose is to increase the cost of ammunition for law abiding gun owners.
The story says it will be done in batches. We’re supposed to think its like DNA but its not.
Second, rubber gloves are really really cheap.
Why stop with this? Why not just take a DNA sample from everyone and put them in jail for thinking bad thoughts.
The UK is such a diabolical mess that I would not use them for an example of anything positive.
