A signal-locked clamped hybridization chain reaction nanoamplifier for rapid and highly sensitive analysis of Aβ42.

Amyloid-beta 42 (Aβ42) is a core biomarker associated with Alzheimer's disease (AD), but accurate quantification of low-abundance plasma Aβ42 remains challenging because of matrix interference, limited assay sensitivity, and time-consuming procedures in conventional methods. Herein, we developed an enzyme-free fluoresc...
