The researchers use a conjugate of the deoxyadenosine
deaminase with a catalytically impaired Cas9 to convert A to I at a target site and to nick the opposite strand.

with magnetic iron oxide in immunoprotective alginate microcapsules and then remotely triggered cytosine

Base editors borrow from CRISPR's components — guide RNAs (gRNAs) and Cas9 or other nucleases — but don't cut the double helix and instead chemically alter single bases
with deaminase enzymes such as TadA and ADAR.
