Magnetic reluctance, or magnetic resistance, is a concept used in the analysis of magnetic circuits. It is defined as the ratio of magnetomotive force (mmf) to magnetic flux . It represents the opposition to magnetic flux, and depends on the geometry and composition of an object.
In 2021, Jinwoo Cheon's research group has successfully developed the magneto-mechanical genetics which uses magnetic stimulation derived mechanical force in mammalian. [7] In this study, magnetic torque by rotating magnetic field was employed to activate the mechanosensitive cation channel Piezo1.
It is the property of certain substances or phenomena that give rise to magnetic fields: =, where Φ is the magnetic flux and is the reluctance of the circuit. It can be seen that the magnetomotive force plays a role in this equation analogous to the voltage V in Ohm's law , V = IR , since it is the cause of magnetic flux in a magnetic circuit ...
Nucleic acid NMR is the use of nuclear magnetic resonance spectroscopy to obtain information about the structure and dynamics of nucleic acid molecules, such as DNA or RNA.It is useful for molecules of up to 100 nucleotides, and as of 2003, nearly half of all known RNA structures had been determined by NMR spectroscopy.
Magnetic complex reluctance (SI Unit: H −1) is a measurement of a passive magnetic circuit (or element within that circuit) dependent on sinusoidal magnetomotive force (SI Unit: At·Wb −1) and sinusoidal magnetic flux (SI Unit: T·m 2), and this is determined by deriving the ratio of their complex effective amplitudes.[Ref. 1-3] = ˙ ˙ = ˙ ˙ =
Magnet-assisted transfection is a transfection method which uses magnetic interactions to deliver DNA into target cells. Nucleic acids are associated with magnetic nanoparticles, and magnetic fields drive the nucleic acid-particle complexes into target cells, where the nucleic acids are released. [1] [2]
Magnetobiology is the study of biological effects of mainly weak static and low-frequency magnetic fields, which do not cause heating of tissues. Magnetobiological effects have unique features that obviously distinguish them from thermal effects; often they are observed for alternating magnetic fields just in separate frequency and amplitude intervals.
The collection of DNA molecules of various truncated lengths therefore informs the frequency of reaction at every base position, which reflects the structure profile along the RNA. This is traditionally assayed by running the DNA on a gel , and the intensity of bands inform the frequency of observing a truncation at each position.
