Abstract

The effects of anionic and cationic nanoparticles (15 and 100 nm in diameter) on the stability of the secondary structure of DNA were studied in DNA denaturation and renaturation processes. The results showed that DNA denaturation is greatly inhibited in the presence of cationic nanoparticles. In contrast, in the presence of even large amounts of anionic nanoparticles, the DNA melting transition occurs at the original melting temperature. The effects of the size and concentration of nanoparticles on DNA denaturation are discussed.
