Blue emitting gold nanoclusters templated by poly-cytosine DNA at low pH and poly-adenine DNA at neutral pH
(Royal Society of Chemistry, 2012-07-11)Blue fluorescent gold nanoclusters were prepared in the presence of poly-cytosine DNAs at low pH and poly-adenine at neutral pH using citrate as the reducing agent; various buffer conditions affecting the synthesis have ... -
Citrate inhibition of cisplatin reaction with DNA studied using fluorescently labeled oligonucleotides: implication for selectivity towards guanine
(Royal Society of Chemistry, 2013-10-21)The reaction between cisplatin and DNA is conveniently studied using fluorescently labeled oligonucleotides and gel electrophoresis; as an example of application, the inhibition of this reaction by citrate is demonstrated, ... -
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 ...
