Parts-per-Million of Polyethylene Glycol as a Non-Interfering Blocking Agent for Homogeneous Biosensor Development
(American Chemical Society, 2013-11-05)
Many homogeneous assays are complicated by the adsorption of probe molecules by the surface of reaction vessels, which are often made of polypropylene or polystyrene-based plastics. To solve this problem, many protein and ...
Nanodiamond decorated liposomes as highly biocompatible delivery vehicles and a comparison with carbon nanotubes and graphene oxide
(Royal Society of Chemistry, 2013-12-21)
Studying interactions between nano-carbons and lipid membranes is important for multiplexed drug delivery, device fabrication and for understanding toxicity. Herein, we report that nanodiamond (ND, sp3 carbon) forms a ...
Rationally Designed Nucleobase and Nucleotide Coordinated Nanoparticles for Selective DNA Adsorption and Detection
(American Chemical Society, 2013-12-17)
Nanomaterials for DNA adsorption are useful for sequence-specific DNA detection. Current materials for DNA adsorption employ electrostatic attraction, hydrophobic interaction, or π–π stacking, none of which can achieve ...
Visual optical biosensors based on DNA-functionalized polyacrylamide hydrogels
Biosensors are devices that can provide quantitative or semi-quantitative analytical information about target molecules, where molecular recognition is based on biomolecular interactions. In recent years, DNA has emerged ...
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, ...
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.
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, ...
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 ...
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.
