American researchers at the University of Rhode Island have developed a new device that can detect TATP, a homemade explosive favored by terrorists because it's made with common household chemicals. The device, funded by a $1 million grant from the Department of Homeland Security, is designed to compete with bomb-sniffing dogs and operate 24/7 without needing breaks.

Why it matters

TATP is a highly volatile explosive that has been used in several terrorist attacks. The new detection device could help improve security and public safety by providing a reliable way to identify this dangerous substance, even in small trace amounts.

The details

The TATP detection device was designed by Professor Otto Gregory at the University of Rhode Island's Center of Explosives Detection. It uses an electronic trace detection system that can identify TATP at concentrations as low as 1 part per billion, even in closed spaces like airports. In testing, the device was able to quickly detect the presence of TATP in a small vial sample.

  • The University of Rhode Island received a $1 million grant from the Department of Homeland Security to develop the TATP detection device.
  • The device will enter real-world testing later this year.

What’s next

The device will enter real-world testing later this year with the goal of making it small enough to be used on turnstiles or worn by officers.

The takeaway

This new TATP detection device represents an important advancement in security technology that could help prevent terrorist attacks involving this dangerous homemade explosive.
