Researchers have created a new version of CRISPR that can edit free floating DNA in a test-tube, instead of only being able to operate on DNA within a living cell. This CRISPR sandbox can be used to test CRISPR on specific test samples, which would allow custom CRISPR diagnosis of cancer cells. The team involved are looking for commercial partners to help deevlop a CRISPR-on-a-chip product for cancer diagnosis.
