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 ...
Toward Fast and Quantitative Modification of Large Gold Nanoparticles by Thiolated DNA: Scaling of Nanoscale Forces, Kinetics, and the Need for Thiol Reduction
(American Chemical Society, 2013-08-01)
We have recently reported on the fast and quantitative adsorption of DNA to 13 nm gold nanoparticles (AuNPs) at pH 3. This is in contrast to most traditional methods at neutral pH, where the adsorption is both slow and ...
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 ...
Adsorption of DNA Oligonucleotides by Titanium Dioxide Nanoparticles
(American Chemical Society, 2014-01-28)
Titanium dioxide (TiO2) or titania shows great promise in detoxification and drug delivery. To reach its full potential, it is important to interface TiO2 with biomolecules to harness their molecular recognition function. ...
