Biopsies in the future may be painless and noninvasive, thanks to smart laser technology being developed at Michigan State University.

To test for skin cancer, patients today must endure doctors cutting away a sliver of skin, sending the biopsy to a lab and anxiously awaiting the results. Using laser microscopes that deploy rapid, ultra-short pulses to identify molecules, doctors may soon have the tools to painlessly scan a patient’s troublesome mole and review the results on the spot, said Marcos Dantus.

The apparently random self-assembly of molecular threads into the proteins that make the body work is far less frantic than previously thought, Michigan State University scientists say. That discovery could be a key to help unlock the nature of some diseases.

How proteins spontaneously “fold” from wiggling chains of amino acids into a wide variety of functional – or malfunctioning – three-dimensional molecules is one of the biggest mysteries in biochemistry.
