Researchers at Harvard University and Michigan State University have created an intelligent laser technology that may allow noninvasive and painless skin cancer biopsies.
Until now, skin cancer biopsies are done by cutting a slice of skin and then analyzing it in a laboratory. The new laser technology will enable physicians to analyze the results instantly by utilizing laser microscopes that generate quick, ultra-short laser pulses to detect molecules in the mole.
The laser technology may also enable scientists to analyze the penetration process of drugs in tissue and the interaction between the tissues and drugs. These advancements reduce the possibilities of possible side effects and thus accelerates the production cycle time for new drugs.
Marcos Dantus of Michigan State University said that the new laser technology enables selective agitation of compound, even those with minute spectroscopic variations. He further said that the technology can be used to shape the laser pulse and agitate one compound or other based on their vibrational signatures, thus providing superior contrast.
Dantus continued that the capability to image with molecular sensitivity and specificity would lead to a wide range of applications in homeland security and medicinal field. The laser technology can also help in determining traces of dangerous materials from a distance.
