Protection and Promotion of UV Radiation-Induced Liposome Leakage via DNA-Directed Assembly with Gold Nanoparticles
DNA-functionalized gold nanoparticles and liposomes are assembled by a linker DNA. The gold nanoparticles can either protect the liposome from UV radiation induced leakage or can promote the leakage, depending on the DNA ...
Platinated DNA oligonucleotides: new probes forming ultrastable conjugates with graphene oxide
(Royal Society of Chemistry, 2014-06-21)
Metal containing polymers have expanded the property of polymers by involving covalently associated metal complexes. DNA is a special block copolymer. While metal ions are known to influence DNA, little is explored on its ...
Light-Activated Metal-Coordinated Supramolecular Complexes with Charge-Directed Self-Assembly
(American Chemical Society, 2013-02-21)
Metal-coordinated materials are attractive for many applications including catalysis, sensing, and controlled release. Adenine and its derivatives have been widely used to generate many coordination complexes, polymers, ...
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, ...
Oxidation Level-Dependent Zwitterionic Liposome Adsorption and Rupture by Graphene-based Materials and Light-Induced Content Release
Liposomes may be stably adsorbed or ruptured on graphene-based materials, depending on the oxidation state of graphene. IR-induced liposome leakage is achieved, since graphene oxide does not induce liposome leakage spontaneously.
DNA stabilized silver nanoclusters for ratiometric and visual detection of Hg2+ and its immobilization in hydrogels
DNA oligomers are particularly interesting templates for making silver nanoclusters (AgNCs) as different emission colors can be obtained by varying the DNA sequence. Many AgNCs have been used as Hg2+ sensors since Hg2+ ...
DNA duplex stabilization in crowded polyanion solutions
(Royal Society of Chemistry, 2013-02-14)
The melting temperature of duplex DNA is much higher in polyanions than in non-ionic polymers with similar ionic strength, suggesting an additional electrostatic contribution on top of the excluded volume effect.
Functional nucleic acids for detecting bacteria
(De Gruyter, 2013-01-31)
Bacterial infection represents one of the leading causes of disease and death, and as such, bacterial detection is an important step in managing infectious diseases. The current protocol requires growing cell cultures, ...
Correlation of photobleaching, oxidation and metal induced fluorescence quenching of DNA-templated silver nanoclusters
(Royal Society of Chemistry, 2013-04-07)
Few-atom noble metal nanoclusters have attracted a lot of interest due to their potential applications in biosensor development, imaging and catalysis. DNA-templated silver nanoclusters (AgNCs) are of particular interest ...
Extraction of DNA staining dyes from DNA using hydrophobic ionic liquids
(Royal Society of Chemistry, 2013-05-18)
The partition of oligonucleotides and DNA staining dyes into a few hydrophobic ionic liquids has been studied, where the oligonucleotides remain in the aqueous phase and all the DNA staining dyes are extracted in the ionic ...
