COLORIMETRIC DETECTION OF SINGLE - AND DOUBLE-STRANDED DNA ON GOLD NANOPARTICLES. Authors: S. BOCA, S. ASTILEAN, O. POPESCU, I. LUPAN. |

Abstract: In this work we report the use of gold nanoparticles (AuNPs) for optical detection of single and double-stranded DNA. The linkage of DNA sequences to gold nanoparticles was demonstrated by the modification of spectral position and intensity of plasmon resonance band and the chemical stabilization that DNA confers to gold particles against a standard aggregation test. Keywords. Gold nanoparticles, Optical detection, Plasma resonance in DNA |
