A laser beam which vibrates the molecules could help to detect improvised explosive devices, the researchers say.
Each molecule vibrates with a single frequency - so that the laser can "feel" the bombs during the mass digitization of a safe distance.
The team's work at Michigan State University, is another attempt to reduce the number of deaths caused by bombs in places like Afghanistan.
The research appears in the journal Applied charts.
Improvised explosive device a homemade bomb and more than half of the deaths of coalition soldiers in Iraq and Afghanistan is the result of an IED.
The lead developer of the laser sensor, Dr. Marcos said Dantus IED detection have always been a challenge because the environment of compounds that mask the molecules bomb.

"After the sensitivity molecular structure is crucial to identify explosives and prevent the evacuation of buildings and unnecessary road closures due to false alarms," he said.
The invention uses a laser beam to study the chemical composition of an object at a distance from the laser.
The package combines short pulses as "kick" for the molecules to vibrate with longer pulses.
"The laser and the method we developed originally scheduled for microscopes, but we were able to adapt and extend its use to demonstrate its effectiveness for the remote detection of explosives," said Dr. Dantus.
Researcher said that he was not able to describe the technology behind the invention in great detail, because of the sensitive nature of the project.
"I can not give details of its implementation," he told BBC News.
"All we are saying that it is able to detect explosives standoff distance."
Bombs at airports
Many different devices and techniques have been developed to help detect bombs safely.
UK scientist Dr Graham Turnbull at the University of St Andrews, who did a lot of research in this area, told the BBC that the latest research is a step forward in the stand-off detection of explosives - even though in the exploratory phase.
"Our work shows that the laser spectroscopy technique called" coherent anti-Stokes Raman spectroscopy "can be used for very sensitive stand-off detection of explosives," he said.
"The researchers suggest that their technique is sensitive - can detect low concentrations of explosives, a few millionths of a gram per square centimeter at a distance of one meter.
"They also show that it is very selective, and can even distinguish between very similar molecules explosives - which could be important in complex environments such as airports, where there may be substances that give false positive innocents with other remote sensing techniques."
Robot dog nose
Half of 2010, Dr. Turnbull and his team developed the laser technique was able to perceive the hidden explosives such as "Pumping" Plastic polyfluorene called with photons of light from another source.
They found a laser jet of explosive vapors such as TNT.
Dr Turnbull has suggested placing the robot, such as a laser, perhaps by remote control, a vehicle that would be able to "sniff around" in the mine, looking for clouds of steam.
"It 'a dusty road in Afghanistan, there are relatively few things that can cause false positives, and certainly could have a potential in this industry," said Turnbull.
"Basically it is an artificial nose to make a robot dog."
