Synthesis and Properties of Novel Silver-Containing DNA Molecules.
Migration of silver atoms from silver nano-particles selectively to a double-stranded poly(dG)-poly(dC) polymer leads to metallization of the DNA. As a result the DNA molecules become shorter and thicker (higher), as evident from the atomic force microscopy imaging analysis. The metalized molecules can be detected by transmission and scanning electron microscopy in contrast to the initial non-metalized ones.
