Phase Transition of DNA-Linked Gold Nanoparticle [PDF]

Physica A, 321 (2003) 164-169., 2001
Melting and hybridization of DNA-capped gold nanoparticle networks are investigated with optical absorption spectroscopy. Single-stranded, 12-base DNA-capped gold nanoparticles are linked with complementary, single-stranded, 24-base linker DNA to form particle networks.

Linker-mediated self-assembly of mobile DNA-coated colloids [PDF]

Science Advances, 6, eaaz6921 (2020), 2019
Developing construction methods of materials tailored for given applications with absolute control over building block placement poses an immense challenge. DNA-coated colloids offer the possibility of realising programmable self-assembly, which, in principle, can assemble almost any structure in equilibrium, but remains challenging experimentally ...

Bioelectronic DNA detection of human papillomaviruses using eSensor™: a model system for detection of multiple pathogens [PDF]

BMC Infectious Diseases, 2003
Background We used human papillomaviruses (HPV) as a model system to evaluate the utility of a nucleic acid, hybridization-based bioelectronic DNA detection platform (eSensor™) in identifying multiple pathogens.

Sequence sensitivity of breathing dynamics in heteropolymer DNA [PDF]

, 2006
We study the fluctuation dynamics of localized denaturation bubbles in heteropolymer DNA with a master equation and complementary stochastic simulation based on novel DNA stability data. A significant dependence of opening probability and waiting time between bubble events on the local DNA sequence is revealed and quantified for a biological sequence ...

Breathing dynamics in heteropolymer DNA [PDF]

, 2006
While the statistical mechanical description of DNA has a long tradition, renewed interest in DNA melting from a physics perspective is nourished by measurements of the fluctuation dynamics of local denaturation bubbles by single molecule spectroscopy. The dynamical opening of DNA bubbles (DNA breathing) is supposedly crucial for biological functioning

Monte Carlo implementation of supercoiled double-stranded DNA [PDF]

, 1999
Metropolis Monte Carlo simulation is used to investigate the elasticity of torsionally stressed double-stranded DNA, in which twist and supercoiling are incorporated as a natural result of base-stacking interaction and backbone bending constrained by hydrogen bonds formed between DNA complementary nucleotide bases.

Colloidal Flying Carpets [PDF]

arXiv, 2009
DNA plays a special role in polymer science not just because of the highly selective recognition of complementary single DNA strands but also because bacteria can express DNA chains that are very long yet perfectly monodisperse. The latter reason makes long DNA molecules widely used as model systems in polymer science.

Base Orientation of Second DNA in RecA·DNA Filaments. Analysis by combination of linear dichroism and small angle neutron scattering in flow-oriented solution [PDF]

, 1998
To gain insight into the mechanism of pairing two complementary DNA strands by the RecA protein, we have determined the nucleobase orientation of the first and the second bound DNA strands in the RecA·DNA filament by combined measurements of linear ...

A highly sensitive electrochemical genosensor based on Co-porphyrin-labelled DNA [PDF]

, 2014
We report the use of Co-porphyrins as electrochemical tags for a highly sensitive and selective genosensor. An avian influenza virus-based DNA sequence characteristic of H5N1 was detected at femtomolar levels from competing non-complementary sequences ...

Comprehensive view of microscopic interactions between DNA-coated colloids [PDF]

, 2021
The self-assembly of DNA-coated colloids into highly-ordered structures offers great promise for advanced optical materials. However, control of disorder, defects, melting, and crystal growth is hindered by the lack of a microscopic understanding of DNA-mediated colloidal interactions. Here we use total internal reflection microscopy to measure in situ
