Abstract

Nanometersized Lcysteinecapped ZnS particles were synthesized by a colloidal aqueous method The functionalized nanoparticles are watersoluble and suitable for biological applications In TrisHCl buffer solution nucleic acids combine with cysteinecapped nanoZnS particles by intermolecular forces to form larger nanoparticles There are two resonance light scattering peaks at 3045 nm and 3738 nm respectively The enhanced RLS is related to the concentration of nucleic acids in the range of 004 to 12 µg mL−1 for calf thymus DNA and 02 to 10 µg mL−1 for fish sperm DNA The detection limits 3δ are 19 ng mL−1 for calf thymus DNA and 23 ng mL−1 for fish sperm DNA respectively Four synthetic samples were analyzed satisfactorily
