Under the premise of eliminating multivalent interactions, we found that the distance between aptamer and nanoparticle could affect the affinity between nanoprobe and target. Furthermore, we found that keeping a certain distance between aptamer and nanoparticle could effectively improved the recognition efficiency of the aptamer nanoprobe and target. It shows that the rigidity of nanomaterials could maintain the spatial structure of the aptamer.While ultraviolet light (UV) absorbance detection is th
