Reversibly linking DNA strands using light/ reduction-oxidation signals

https://phys.org/news/2026-02-dna-redox-cues-reversibly-link.html

"switchable DNA linkage uses specific chemical modifications (redox-active labels) triggering DNA strands to bond/ separate in response to different stimuli: laser, LED, presence of certain antioxidants/ oxidants... dynamic nanomaterials that can assemble, disassemble, reconfigure... targeted drug delivery releasing cargo only when triggered, synthetic tissues/ hydrogels that can change stiffness/ elasticity, molecular computing using DNA as logic gates that respond to chemical/ light triggers"
