Abstract

Assembly of gold nanoparticles (AuNP) into designer architectures with reliablity is important for nanophotonics and nanoelectronics applications. Toward this goal we present a new strategy to prepare AuNPs monofunctionalized with lipoic acid modified DNA oligos. This strategy offers increased bonding strength between DNA oligos and AuNP surface. These conjugates are further selectively mixed with other DNA strands and assembled into fixed sized DNA nanostructures carring a discrete number of AuNPs at desired positions. Atomic force microscopy imaging reveals a dramatically improved yield of the AuNPs on DNA tile structure compared to the ensembles using monothiolate AuNP-DNA conjugates.
