Genes on the - laser - firing line.

Genes on the (laser) firing line

Like a nail puncturing a tire, lasers apparently make tiny, self-sealing holes in cell membranes through which genetic material can enter, say scientists at the University of California at Irvine. In the "laser-mediated gene transfer' technique, cells are irradiated with an yttrium-aluminum garnet laser beam while suspended in a liquid containing foreign DNA. According to an article in the June PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES (Vol.84, No.12), the DNA is successfully incorporated into the genetic machinery of host cells. The authors suggest that the method may circumvent problems in standard DNA transfer techniques.
