  • Title: Specific detection of cysteine and homocysteine: recognizing one-methylene difference using fluorosurfactant-capped gold nanoparticles.
    Author: Lu C, Zu Y.
    Journal: Chem Commun (Camb); 2007 Oct 07; (37):3871-3. PubMed ID: 18217674.
    Abstract:
    Aggregation of fluorosurfactant-capped gold nanoparticles could be induced selectively by cysteine and homocysteine and, when solution ionic strength was low, the kinetics of homocysteine-induced aggregation of large size nanoparticles (approximately 40 nm) was much faster than that induced by cysteine, leading to specific detection of homocysteine in the presence of excess cysteine.
