Fabrication of porcine DNA biosensor based on ruthenium bipyridine complex [PDF]
, 2016 Electrochemical DNA biosensor for detection of porcine oligonucleotides based on ruthenium (II) as label redox complex has been developed. The system of biosensor is based on the modified screen printed carbon electrode (SPE) with goldnanoparticles ...

Loop Dynamics in DNA Denaturation [PDF]
, 2006 The dynamics of a loop in DNA molecules at the denaturation transition is studied by scaling arguments and numerical simulations. The autocorrelation function of the state of complementary bases (either closed or open) is calculated. The long-time decay of the autocorrelation function is expressed in terms of the loop exponent c both for homopolymers ...

Molecular Oncology, EarlyView.Urine is a rich source of biomarkers for cancer detection. Tumor‐derived material is released into the bloodstream and transported to the urine. Urine can easily be collected from individuals, allowing non‐invasive cancer detection. This review discusses the rationale behind urine‐based cancer detection and its potential for cancer diagnostics ...

Crowding-induced hybridization of single DNA hairpins [PDF]
, 2015 It is clear that a crowded environment influences the structure, dynamics, and interactions of biological molecules, but the complexity of this phenomenon demands the development of new experimental and theoretical approaches.

Differential stability of DNA based on salt concentration [PDF]
arXiv, 2015 Intracellular positive ions neutralise negative charges on the phosphates of a DNA strand conferring greater strength on the hydrogen bonds that connect complementary strands into a double helix and so confer enhanced stability. Beyond a certain value of salt concentration, the DNA molecule displays a unstable nature {\it in vivo} as well as {\it in ...

Molecular Oncology, EarlyView.Circulating tumor DNA (ctDNA) offers a possibility for different applications in early and late stage breast cancer management. In early breast cancer tumor informed approaches are increasingly used for detecting molecular residual disease (MRD) and early recurrence. In advanced stage, ctDNA provides a possibility for monitoring disease progression and

Supramolecular DNA Three-Way Junction Motifs With a Bridging Metal Center
Frontiers in Chemistry, 2020 Various nano-sized supramolecular architectures have been constructed from DNA molecules via sequence-dependent self-assembly. A DNA three-way junction (3WJ), consisting of three oligonucleotides that are partially complementary to each other, is one of ...
