Fig. 6From: Hybrid material of structural DNA with inorganic compound: synthesis, applications, and perspective(Reproduced with permission [58])DNA pyramid structures including gold nanoparticles and upconversion nanoparticles. The DNA pyramid disintegrates its original structures upon binding specially to intracellular miRNAs, thus restoring suppressed optical properties of the upconversion nanoparticles involved in the systemBack to article page
