Aryl ketones are photolabile caging groups if installed at the N7 position of guanosine or the N1 position of adenosine whereas common photocaging groups derived from the ortho‐nitrobenzyl moiety were not suitable.

DNA-encoded libraries are increasingly used of drug identification. However, the reactivity of the DNA imposes limitations on the choice of chemical methods for encoded library synthesis. Amphiphilic block copolymers covalently functionalized with sulfonic acid moieties in the lipophilic portion assemble in water and locate the Brønsted catalyst in micelles. These acid nanoreactors enabled the reaction of DNA-conjugated aldehydes to diverse substituted tetrahydroquinolines and aminoimidazopyridines by Povarov and Groebke–Blackburn–Bienaymé reactions, respectively.

Small DNA circles can serve as templates for rolling circle amplification (RCA), which is a common and extremely robust amplification mechanism for nucleic acids. We discovered a strong template length-dependent amplification efficiency bias of RCA with the same periodicity as B-DNA.
