A controllable silver nanoparticle aggregate system has been synthesized by adding different amounts of ethanol to cetyltrimethylammonium bromide (CTAB) capped silver nanoparticles (Ag-nps), which...
Atomic force microscopic study of low temperature induced disassembly of RecA-dsDNA filaments (2008)
Wang, L, Sun, Lanlan, Sun, Yujing, Peng, Chongyang, ...
The assembly and disassembly of RecA-DNA nucleoprotein filaments on double-stranded DNA (dsDNA) or single-stranded DNA (ssDNA) are important steps for homologous recombination and DNA repair. The...

We reported a simple method to synthesize gold nanoparticles (NPs) by photoreducing HAuCl4 in acetic acid solution in the presence of type I collagen. It was found that the collagen takes an...
Self-assembled gold nanoparticle chains in presence of silver ions (2007)
Wei, Gang, Wang, Li, Guo, Cunlan, Sun, Yujing, ...
A simple method has been developed to assemble gold nanoparticles to generate 1D assemblies by the assistance of silver ions. The lengths of nanoparticle chains can be controlled by adjusting the...
Effects of bridge ions, DNA species, and developing temperature on flat-lying DNA monolayers (2007)
Guo, Cunlan, Sun, Lanlan, Wei, Gang, Peng, Chongyang, Wang, Li, ...
Recently, we have successfully constructed flat-lying DNA monolayers on a mica surface (J. Phys. Chem. B 2006, 110, 10792-10798). In this work, the effects of various factors including bridge ions,...
