Dissecting Colloidal Stabilization Factors in Crowded Polymer Solutions by Forming Self-Assembled Monolayers on Gold Nanoparticles
(American Chemical Society, 2013-05-21)
An ideal colloidal system should be highly stable in a diverse range of buffer conditions while still retaining its surface accessibility. We recently reported that dispersing citrate-capped gold nanoparticles (AuNPs) in ...
Instantaneous and Quantitative Functionalization of Gold Nanoparticles with Thiolated DNA Using a pH-Assisted and Surfactant-Free Route
(American Chemical Society, 2012-05-02)
The attachment of thiolated DNA to gold nanoparticles (AuNPs) has enabled many landmark works in nanobiotechnology. This conjugate chemistry is typically performed using a salt-aging protocol where, in the presence of an ...
Surface Science of DNA Adsorption onto Citrate-Capped Gold Nanoparticles
(American Chemical Society, 2012-02-28)
Single-stranded DNA can be adsorbed by citrate capped gold nanoparticles (AuNPs), resulting in increased AuNP stability, which forms the basis of a number of biochemical and analytical applications, but the fundamental ...
Polarity Control for Nonthiolated DNA Adsorption onto Gold Nanoparticles
(American Chemical Society, 2013-05-21)
Gold nanoparticles (AuNPs) functionalized with thiolated DNA have enabled many studies in nanoscience. The strong thiol/gold affinity and the nanoscale curvature of AuNPs allow the attached DNA to adapt an upright conformation ...
Fast pH-assisted functionalization of silver nanoparticles with monothiolated DNA
(Royal Society of Chemistry, 2012-10-18)
Attaching monothiolated DNA to silver nanoparticles has been achieved at pH 3.0 in 30 minutes and difficulties associated with DNA attachment to AgNPs at neutral pH have been revealed by studying DNA adsorption kinetics.
