Enzymatic enhancing of triplet–triplet annihilation upconversion by breaking oxygen quenching for background-free biological sensing

Triplet-triplet annihilation upconversion (TTA-UC) nanoparticles (NPs) are a promising material for diverse applications, but TTA-UC is sensitive to oxygen, which hinders its biological utility. Here, the authors report an enzymatic method to deplete oxygen and amplify the upconversion of TTA-UCNP i...
