Photoinduced inhibition of DNA unwinding in vitro with water-soluble polymers containing both phosphorylcholine and photoreactive groups
Nile blue (NB)-tagged DNA helix-targeting amphiphilic photoreactive 2-methacryloyloxyethyl phosphorylcholine (MPC) polymer, poly(MPC-co-3-methacryloyloxy-2-hydroxypropyl-4-oxybenzophenone-co-2-trimethylammonium ethyl methacrylate chloride) (PMHT–NB), containing a cationic group to facilitate cell membrane penetration and a benzophenone (BP) group to promote photoinduced conjugation wi...

Water-Soluble Polymers Bearing Phosphorylcholine Group and Other Zwitterionic Groups for Carrying DNA Derivatives
Water-soluble polymers with equal positive and negative charges in the same monomer unit, such as the phosphorylcholine group and other zwitterionic groups, exhibit promising potential in gene delivery with appreciable transfection efficiency, compared with the traditional poly(ethylene glycol)-based polycation–gene complexes. These zwitterionic polymers with various archite...

Polymer, 50, 930-935: Modeling single chain elasticity of single-stranded DNA: A comparison of three models
The
dominant models of polymers, i.e. the freely jointed chain (FJC) model, the wormlike
chain (WLC) model and the freely rotating chain (FRC) model are modified by
integrating the inherent single-molecule elasticity obtained from quantum
mechanics (QM) ab-initio calculations. The QM modified models have been
utilized to generate fitting curves for single-stranded DNA obtained in organic
solvent. ...

Phys. Chem. Chem. Phys., 2010: The Possible Roles of Water in the Prebiotic Chemical Evolution of DNA
There
is no doubt that water is pivotal to life. Yet, as the emergence of life is
still a big challenge in science, the detailed involvement of water in that
process is not well recognized. Following the clues provided by recent
single-molecule studies on DNA, we attempt to elucidate the possible roles of
water in the prebiotic chemical evolution. Water has been long recognized as an
important rea...

J. Am. Chem. Soc. 2006: Weakly bound water molecules shorten single-stranded DNA
In this paper, we measure
the single chain elasticity of an oligomer ssDNA in both aqueous and
non-aqueous, apolar liquid environments by AFM-based single molecule force
spectroscopy. We find a marked deviation between the force-extension relations
recorded in the two ambients. This difference is attributed to the additional
energy required to break the H-bond directed water bridges around ssDNA c...

J. Am. Chem. Soc. 2007: Double Stranded DNA Dissociates into Single Strands when Dragged into a Poor Solvent
DNA displays a richness of biologically relevant
supramolecular structures, which depend on both sequence and ambient. The effect of dragging
dsDNA from water into poor solvent on the double-stranded structure is still
unclear because of condensation. Here
we employ single molecule techniques based on atomic force microscopy and molecular dynamics (MD) simulations to investigate the change in...

Studies on Synthesis of Water-Soluble Polymer-supported Transition Metal Polypyridyl Complexes and their interaction with DNA
Five water-soluble polymer-supported transition metal
polypyridyl complexes were synthesized from polyacrylic acid -co-
N-vinyl pyrrolidone, 2-methyl-3-hydroxyl benzaldehyde, o-phenanthroline and
metal acetate salts. Infrared spectra (IR), thermo-gravimetric and differential
thermal analysis (TG-DTA), Inductance Coupling Plasma (ICP) and X-ray
photoelectron spectroscopy (XPS) measurement technolog...

A label-free electrochemistry biosensor based flower-like 3-dimensional ZnO superstructures for detection of DNA arrays
A novel label-free DNA hybridization biosensor was fabricated using flower-like 3-dimensional (3D) ZnO superstructures as an enhanced sensing platform and employing chitosan (CS) as a film-forming material. A highly sensitive electrochemical DNA sensor was constructed by homogenously distributing Au nanoparticles (AuNPs) on the ZnO–CS matrix. The electrochemical performance of the designed elec...
