DNA-like Helices as Nanosized Polarizers of Electromagnetic Waves
Frontiers in Nanotechnology, 2022 The possibility of using a conducting double DNA-like helix as the basis of an electromagnetic wave polarizer, which converts an incident linearly polarized wave into a reflected wave with circular polarization, has been shown. A high-frequency resonance

Proceedings of the National Academy of Sciences, 1998 Using circular DNA to measure the degree of unwinding of the double helix caused by ligand binding was one of the first applications of the specific properties of circular DNA. The approach is conceptually simple. Consider a nicked circular DNA of N base pairs that is bound to molecules of a ligand so that the ratio of bound ligands to base pairs is ...

Single-stranded circular DNA theranostics
Theranostics, 2022 The past decade has witnessed the blossom of nucleic acid therapeutics and diagnostics (theranostics). Unlike conventional small molecule medicines or protein biologics, nucleic acid theranostics have characteristic features such as the intrinsic ability as "information drugs" to code and execute genetic and theranostic information, ready ...

Characterization of the DNA binding activity of structural protein VP1 from chicken anaemia virus
BMC Veterinary Research, 2018 Background Chicken anaemia virus (CAV) is commonly found in poultry. VP1 is the sole structural protein of CAV, which is the major component responsible for capsid assembly. The CAV virion consists of the VP1 protein and a viral genome. However, there is

Circular DNA tumor viruses make circular RNAs [PDF]
Proceedings of the National Academy of Sciences, 2018 Significance Circular RNAs (circRNAs) play critical physiologic functions, but it is not known whether human DNA viruses express circRNAs. We surveyed Epstein−Barr virus (EBV) and Kaposi’s sarcoma herpesvirus (KSHV) tumors and cell lines, and found specific circRNAs expressed from both viruses.

Small Circular DNA Molecules as Triangular Scaffolds for the Growth of 3D Single Crystals
Biomolecules, 2020 DNA is a very useful molecule for the programmed self-assembly of 3D (three dimension) nanoscale structures. The organised 3D DNA assemblies and crystals enable scientists to conduct studies for many applications such as enzymatic catalysis, biological ...

Construction of DNA hemicatenanes from two small circular DNA molecules. [PDF]
PLoS ONE, 2015 DNA hemicatenanes, one of the simplest possible junctions between two double stranded DNA molecules, have frequently been mentioned in the literature for their possible function in DNA replication, recombination, repair, and organization in chromosomes ...
