This paper demonstrates that DNA can be used to control the synthesis of silver nanoplates with different morphologies using spherical silver seeds. UV-vis spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy were used to characterize the synthesized nanoparticles. Silver nanoprisms were encoded by poly C and poly G, while silver flower bouquets and silver nanodiscs were synthesized using poly A and poly T, respectively. The length of DNA was found to have little effect on the morphology of silver nanoparticles. Moreover, the synthesized silver nanoplates were found to have high SERS (surface enhanced Raman scattering) enhancement ability, good antibacterial activity, and good biocompatibility. These discoveries will broaden the application of DNA in nanoscience and will provide a new platform to investigate the interaction between DNA sequences and silver nanoparticles.
