In this paper, we have investigated the adsorption properties of different strands of a DNA to the colloidal nanoparticles. We measured the plasmonic spectrums of the nanoparticles under the presence of different oligonucleotids. It is shown that the quality of the adsorption of different strands of DNAs on the nanoparticles strongly depends on the sequence of the DNAs. Between the different bases of a DNA, the base (A) has the best and the base (G) has the worst attachment to the nanoparticles. It is also shown that with increment of the DNA concentration, the adsorption of the silver nanoparticles to the DNAs increases leading to a more protection of the nanoparticles against salt-induced aggregation.
Keywords: Surface plasmon resonance, Gold and silver nanoparticles, Single and double strand DNAs
