Light-Activated Gene Editing

Engineers show that near-infrared light can trigger the release of CRISPR-Cas9 to slow tumor growth

Engineers are making their mark on biotech’s hottest commodity. Chinese scientists today reported that they can control the gene editing tool CRISPR-Cas9 with light.

The method replaces the use of viruses traditionally used to deliver CRISPR gene editing machinery, and gives scientists temporal control over the tool, the researchers said. They published their findings in the journal Science Advances.

The technique has the potential to precisely target and kill cancer cells, says Yujun Song, an author of the paper and a professor in the College of Engineering and Applied Sciences at Nanjing University in China.
