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.
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 ...
Orthogonal Adsorption Onto Nano-Graphene Oxide Using Different Intermolecular Forces for Multiplexed Delivery
Nano-graphene oxide can adsorb both doxorubicin and zwitterionic dioleoyl-sn-glycero-3-phosphocholine (DOPC) liposomes in an orthogonal and non-competing manner with high capacities based on different surface and intermolecular ...
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 ...
Attaching DNA to Nanoceria: Regulating Oxidase Activity and Fluorescence Quenching
(American Chemical Society, 2013-08-14)
Cerium oxide nanoparticles (nanoceria) have recently emerged as a nanozyme with oxidase activity. In this work, we present a few important interfacial properties of nanoceria. First, the surface charge of nanoceria can be ...
Mechanisms of DNA Sensing on Graphene Oxide
(American Chemical Society, 2013-08-20)
Adsorption of a fluorophore-labeled DNA probe by graphene oxide (GO) produces a sensor that gives fluorescence enhancement in the presence of its complementary DNA (cDNA). While many important analytical applications have ...
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 ...
