Selfassembly of metallic nanoparticle arrays by DNA scaffolding
We report the self-assembly of metallic nanoparticle arrays using DNA crystals as a programmable molecular scaffolding. Gold nanoparticles, 1.4 nm in diameter, are assembled in two-dimensional arrays with interparticle spacings of 4 and 64 nm. The nanoparticles form precisely integrated components, which are covalently bonded to the DNA scaffolding. These results show that heterologous chemical...
متن کاملRegulating Virtual Interactions
The evolution of internet has brought about many forms of virtual interactions, like e-learning or e-goverment, whose aim is to achieve an objective that is shared by those parties that interact. It is not unusual that in order for such interactions to be effective, they may require the explicit definition of conventions that participants should abide by, not unlike traditional social interacti...
متن کاملNature of Lithium Interactions with DNA Nucleobases: Theoretical Study
In the present study, the interactions of three different lithium species Li+, Li3+ and CH3Li with several different sites of the most stable tautomers of DNA nucleo-bases are presented. This investigation is based on the results of thermochemical properties, Quantum Theory of Atoms in Molecules (QTAIM) and Natural Bond Orbi...
متن کاملDynamic force spectroscopy of protein-DNA interactions by unzipping DNA.
We demonstrate the first site-specific single-molecule characterization of the prominent activation barrier for the disruption of a protein-DNA binding complex. We achieved this new capability by combining dynamic force spectroscopy with unzipping force analysis of protein association and used the combination to investigate restriction enzyme binding to specific DNA sites. Analysis revealed lif...
متن کاملProbing Rad51-DNA interactions by changing DNA twist
In eukaryotes, Rad51 protein is responsible for the recombinational repair of double-strand DNA breaks. Rad51 monomers cooperatively assemble on exonuclease-processed broken ends forming helical nucleo-protein filaments that can pair with homologous regions of sister chromatids. Homologous pairing allows the broken ends to be reunited in a complex but error-free repair process. Rad51 protein ha...
