New Way of Inserting DNA into Living Cells
A team of scientists have devised a new method of inserting foreign DNA into cells that, they say, is far more gentle and precise than any that have come before it.
Described in the journal Bio-medical Optics Express, the technique includes poking holes on the surface of a cell using a high-powered "femtosecond" laser and retrieving a piece of DNA with "optical tweezers" like a high-tech version of the game Operation.
The process, the researchers say, is an improvement on past methods for a number of reasons, including efficiency (many current techniques are clumsy and often require many tries) as well as its control at the single-cell level.
