摘要：
Embodiments of a method for nucleic acid-mediated control of a nanoparticle shape are disclosed. In some embodiments, one or more nucleic acid oligomers are adsorbed to a metal nanoseed, and additional metal is deposited onto the nanoseed to produce a shaped nanoparticle. In certain embodiments, the nanoseed is gold and the oligomers are 5-100 nucleotides in length. The nanoparticle shape is determined at least in part by the nucleic acid sequence of the oligomer(s). Shaped nanoparticles produced by embodiments of the method include nanoflowers, nanospheres, nanostars, and nanoplates. Embodiments for using the shaped nanoparticles also are disclosed.
