Lasers allow us to selectively excite smart composites - even with small spectroscopic differences, "says Mark Dantus

Biópisias laser can perform a painless and noninvasive. This is the conclusion of the study conducted by researchers from Michigan State University, USA.

The use of laser microscopes that deploy fast pulses and ultra-short for the identification of molecules can be formed as a new tool for doctors to detect diseases like cancer without causing discomfort or pain.

Lasers allow us to selectively excite smart composites - even with small differences spectroscopy. We can shape the laser pulse, exciting a compound or another based on their vibrational signatures, and this gives us an excellent contrast, "explained study leader Marcos Dantus.

Other Applications

The new technology may also have other potential uses such as allowing researchers to examine carefully how certain compounds penetrate the skin and hair. The laser can also better identify how drugs penetrate tissue and how drugs interact and the tissue, reducing the chances of side effects and helping to reduce the time required to bring new drugs to market.

Dantus is also using the technology of laser imaging for detection of trace substances in the distance.

"The ability to visualize with sensitivity and molecular specificity opens a series of applications in medicine and homeland security," he said.
