DNA-DNA hybridization study of Bradyrhizobium strains. [PDF]

International Journal of Systematic and Evolutionary Microbiology, 2001
DNA-DNA hybridizations were performed between Bradyrhizobium strains, isolated mainly from Faidherbia albida and Aeschynomene species, as well as Bradyrhizobium reference strains. Results indicated that the genus Bradyrhizobium consists of at least 11 genospecies, I to XI.

Development of Si-based electrical biosensors: Simulations and first experimental results

Sensing and Bio-Sensing Research, 2015
In this work, we simulated and experimentally assessed the possibility to detect, through electrical transduction, hybridization of DNA molecules on MOS-like devices, having different dielectrics: SiO2, Si3N4 and SiO2/Si3N4/SiO2 (ONO).

Homologies in human and Macasa fuscata chromosomes revealed by in situ suppression hybridization with human chromosome specific DNA libraries [PDF]

, 1992
We established chromosomal homologies between all chromosomes of the human karyotype and that of an old world monkey (Macaca fuscata) by chromosomal in situ suppression (CISS) hybridization with human chromosome specific DNA libraries.

Impact of point-mutations on the hybridization affinity of surface-bound DNA/DNA and RNA/DNA oligonucleotide-duplexes: Comparison of single base mismatches and base bulges

BMC Biotechnology, 2008
Background The high binding specificity of short 10 to 30 mer oligonucleotide probes enables single base mismatch (MM) discrimination and thus provides the basis for genotyping and resequencing microarray applications.

Hybridization and self‐assembly behaviors of surface‐immobilized DNA in close proximity: A single‐molecule perspective

Aggregate, 2022
Solid surfaces that are immobilized with DNA molecules underlie an array of biotechnological devices. These surfaces may also mediate the self‐assembly of hierarchical DNA nanostructures.

Design and analysis of linear cascade DNA hybridization chain reactions using DNA hairpins

New Journal of Physics, 2017
DNA self-assembly has been employed non-conventionally to construct nanoscale structures and dynamic nanoscale machines. The technique of hybridization chain reactions by triggered self-assembly has been shown to form various interesting nanoscale ...

Use of the checkerboard DNA-DNA hybridization technique for bacteria detection in Aedes aegypti (Diptera:Culicidae) (L.)

Parasites & Vectors, 2011
Background Bacteria associated with insects can have a substantial impact on the biology and life cycle of their host. The checkerboard DNA-DNA hybridization technique is a semi-quantitative technique that has been previously employed in odontology to ...

Attaching DNA to Gold Nanoparticles With a Protein Corona

Frontiers in Chemistry, 2020
DNA-functionalized gold nanoparticles (AuNPs) have been widely used in directed assembly of materials, biosensors, and drug delivery. This conjugate may encounter proteins in these applications and proteins may affect not only DNA adsorption but also the

Ultrasensitive hybridization capture: Reliable detection of <1 copy/mL short cell-free DNA from large-volume urine samples.

PLoS ONE, 2021
Urine cell-free DNA (cfDNA) is a valuable non-invasive biomarker with broad potential clinical applications, but there is no consensus on its optimal pre-analytical methodology, including the DNA extraction step.

Modeling the kinetics of hybridization in microarrays [PDF]

, 2007
Conventional fluorescent-based microarrays acquire data after the hybridization phase. In this phase the targets analytes (i.e., DNA fragments) bind to the capturing probes on the array and supposedly reach a steady state.
