New high-tech laser method allows DNA to be inserted ‘gently’ into living cells

“A team of scientists in South Korea have now developed the most precise method ever used to insert DNA into cells. The method combines two high-tech laboratory techniques and allows the researchers to precisely poke holes on the surface of a single cell with a high-powered “femtosecond” laser and then gently tug a piece of DNA through it using “optical tweezers,” which draw on the electromagnetic field of another laser. The team’s approach, which is a breakthrough in precision and control at the single-cell level, was published today in the Optical Society’s (OSA) open-access journal Biomedical Optics Express.”
