Liquid Laser

Using this liquid laser, University of Michigan Professor Xudong Fan has developed a highly sensitive technique for identifying mutated DNA that differs from healthy DNA by a single base. The fine white horizontal line is the capillary cavity that enables the laser to amplify the intrinsic difference in the light signals from healthy and mutated DNA. Image: Nicole Casal Moore

Genes Linked To Cancer Could Be Easier To Detect With Liquid Lasers

Using a liquid laser, University of Michigan researchers have developed a better way to detect the slight genetic mutations that might predispose a person to a particular type of cancer or other diseases.
