  • Title: Simple Colorimetric Detection of Amyloid β-peptide (1-40) based on Aggregation of Gold Nanoparticles in the Presence of Copper Ions.
    Author: Zhou Y, Dong H, Liu L, Xu M.
    Journal: Small; 2015 May 13; 11(18):2144-9. PubMed ID: 25641831.
    Abstract:
    A simple method for specific colorimetric sensing of Alzheimer's disease related amyloid-β peptide (Aβ) is developed based on the aggregation of gold nanoparticles in the presence of copper ion. The detection of limit for Aβ(1-40) is 0.6 nM and the promising results from practical samples (human serum) indicate the great potential for the routine detection.
