Microarray chip based on surface-enhanced raman scattering-chiral anisotropy for ultrasensitive detection of Aβ42 as an Alzheimer’s disease-associated serum biomarker

In this study, a highly sensitive surface-enhanced Raman scattering-chiral anisotropy (SERS-ChA)-based microarray chip was fabricated for the quantitative analysis of β-amyloid protein (Aβ42) in Alzheimer’s disease (AD). To construct the chip, D-type chiral gold nanoparticles (CG...
