Templates for DNA-templated Fe3O4 nanoparticles

The Application of Biomolecules in the Preparation of Nanomaterials

“…Then, the nanoparticles were assembled onto the DNA molecule via certain interactions between DNA and the particles. Based on the electrostatic interaction between the negatively charged DNA and the positively charged nanoparticles, gold nanoaprticles (Nakao et al, 2003), silver nanoparticles Sun et al, 2006), Fe 3 O 4 nanoparticles (Nyamjav et al, 2005) have been self-assembled onto DNA. The representative work in this area is the selfassembly of aniline-capped gold nanoparticles on -DNA carried out by Nakao et al Aniline was first used to reduce HAuCl 4 to produce the aniline-capped gold nanoparticles in one step.…”

“…[64] Two different strategies are utilised to accomplish this. The strategies combine solution templating of inorganic NP onto biomolecules and molecular combing, or the layer-by-layer method and dip-pen nanolithography (DPN).…”

DNA assisted fragmentation of nickel nanoparticle clusters and their spectral properties

“…Therefore we wanted to step in to the nature of interaction of these curiously studied metal nano particles with DNA. Even though in situ preparation of selfassembled DNA-metal nano particles including nickel are addressed by many researchers [13][14][15][16][17][18][19][20][21][22][23][24], we report for the first time, the use of DNA molecule to fragment the pre-formed NiNPs clusters of size 60-70 nm into 5-15 nm and to form a well organized NiNPs embedded tubular DNA structure, which was characterized by AFM, TEM and UVvis, emission and circular dichroic (CD) spectral studies.…”

“…Furthermore, there has been recently reported the use of DNA to control the assembly of AuNPs into tubular architectures, the incorporation of AuNPs into a planar DNA tile array by conjugating each AuNPs with a single DNA strand, which may lead to interesting properties for nanoelectronics and photonics applications [13]. To date, scientists have applied in situ methods to form DNA-templated materials with metals such as silver [14], platinum [15], palladium [16], gold [13,17], cobalt [18], nickel [1,19,20] and copper [21,22] and semiconductors such as cadmium sulfide [23] and iron oxide [24]. In some cases the metal cations change the conformation of DNA [25].…”
