photocontrollable nucleic acid displacement reaction
Engineering MethodPhotocontrollable nucleic acid displacement reaction is a light-gated nucleic acid engineering method used within a near-infrared-activatable cascade recycling amplification system. In the cited implementation, it is integrated with exonuclease III-assisted nucleic acid amplification and upconversion nanoparticles to enable spatiotemporally controllable, signal-amplified mRNA imaging in selected living cancer cells.
