“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.”
