Particularly, the annealing temperature and silica interlayer play important roles in modulating their frameworks and catalytic overall performance. Furthermore, this strategy may pave an alternative way to building non-noble-metal-based composites with yolk-shell structures.Amyloid β-peptide oligomer (AβO) is extensively called the encouraging biomarker for the diagnosis of Alzheimer's disease infection (AD). In this work, we designed a three-dimensional (3D) DNA walker nanoprobe for AβO detection and real time imaging in residing cells as well as in vivo. The presence of AβO triggered the DNAzyme walking strand to cleave the fluorophore (TAMRA)-labeled substrate strand modified in the silver nanoparticle (AuNP) surface and launch TAMRA-labeled DNA fragment, causing the data recovery of fluorescent sign. The whole procedure ended up being independent and continuous, without external gasoline strands or protease, and finally produced plenty of TAMRA fluorescence, attaining sign amplification effect. The nanoprobe allowed the quantitative recognition of AβO in vitro, plus the limit of detection ended up being 22.3 pM. Given the good biocompatibility of 3D DNA walker nanoprobe, we extended this enzyme-free signal amplification method to real-time imaging of AβO. Underneath the microscope, nanoprobe precisely located and visualized the circulation of AβO in living cells. Moreover, in vivo imaging results showed that our nanoprobe could possibly be used to efficiently differentiate the AD mice through the wild-type mice. This nanoprobe with the advantages of great sensitiveness, high specificity, and convenience, provides a superb prospect
