摘要：

The colloidal silver nanoparticles were prepared by the gamma-irradiation of silver nitrate (AgNO3) in a mixture solution of water and 2-propanol in the presence of poly(vinylpyrrolidone) as a colloidal stabilizer. The Ag colloids obtained by gamma-irradiation were characterized by use of XRD and TEM. The surface of the Ag colloids were modified by use of mercaptosuccinic acid (MSA), (D)-cysteine (Cys), and (L)-CYS, respectively. The MSA and (L)-Cys-capped Ag colloids were aggregated because of hydrogen bonding of the carboxylic acid and amino acid group, respectively. From the analysis by CD spectroscopy, it was shown that chiral-enhanced phenomena were obtained in (L)- and (D)-Cys-capped Ag colloids. (C) 2003 Elsevier Science Ltd. All rights reserved.
