Magnetic properties of copper as a constituent of nanobridges formed between spatially fixed deoxyribonucleic acid molecules

The number of copper ions as constituents of a nanobridge that links two deoxyribonucleic acid (DNA) molecules that are fixed in a particle of a liquid-crystalline dispersion has been evaluated from the measurements of the magnetic susceptibility of particles in the liquid-crystalline dispersion of DNA. It has been shown that the experimental data are consistent with both theoretical assumptions on the possible structure of a nanobridge and a thermodynamic model that describes the formation of these bridges.
