According to the US "Daily Science" report, scientists from the University of Manchester in the United Kingdom claimed that a fluorescent film with a color change can be better captured on metal surfaces (such as guns, knives, door handles, etc.) hidden or newly left behind Fingerprints. Basically, if you do not wear gloves, this new fingerprint recognition technology can be identified.
Usually, because of sweat or natural oils, fingers can easily leave a fingerprint on the surface of the object, but because it is easily wiped, this leaves a very big problem for crime scene investigation. According to the British "Guardian", precisely because of this limitation, only about 10% of fingerprints at the crime scene can finally be used as forensic evidence. But new fingerprint recognition technology can at least improve this situation in some cases.
"We often say that we repeatedly confirm that we have put on gloves and do not leave fingerprints on the scene," said a thieves in London. "Any experienced thief will wear gloves anyway. So I think this new fingerprint recognition." Technology is only used to catch luck and catch amateur rookies who do not know how to wear gloves."
Despite the use of advanced science to extract fingerprints that have been wiped, the easiest way for the thieves to avoid this series of fingerprinting problems is to wear gloves. However, once the thief does not wear a glove, whether he has wiped his fingerprint or not, he will be able to find him with his fingerprint recognition technology.
Nanomicro Tech provides a series of Magnetic Particles with narrow size distribution and super-paramagnetism. These small magnetic particles have a resin core and an iron oxide layer sandwiched between the core and an outermost layer. The outermost layer of the particles is inorganic SiO2 or a functionalized polymer which completely covers iron oxide to prevent it from potentially incompatible interaction with biomaterials. These magnetic particles have a very good dispersity with well controlled particle size and narrow particle size distribution.
