  • Title: A sensitive and selective resonance light scattering bioassay for homocysteine in biological fluids based on target-involved assembly of polyethyleneimine-capped Ag-nanoclusters.
    Author: Sun SK, Wang HF, Yan XP.
    Journal: Chem Commun (Camb); 2011 Apr 07; 47(13):3817-9. PubMed ID: 21286655.
    Abstract:
    A specific resonance light scattering bioassay for homocysteine is developed on the basis of target-involved assembly of polyethyleneimine-capped Ag-nanoclusters. The bioassay permits discriminating homocysteine from cysteine, glutathione and other amino acids, and allows sensitive and selective detection of homocysteine with a detection limit of 42 nM.
