magnetic gradient

magnetic gradient

An MRI term for the degree and direction of the linear rate of change of a magnetic field in space, which is one of three linear magnetisation waveforms superimposed on the main magnetic field at specific times within a pulse sequence to select the imaging region or provide necessary spatial localising information.

They magnetized the beads in solution and formed a magnetic gradient to attract the antibody-coated beads to the surface in contact with any bound targets.
Subsequently, the external magnetic gradient enables and enhances the movement of the therapeutic-nanoparticle complex into the tumor environment where the drug is “activated,” resulting in a significant anti-tumor response.

A large number of structures can be interpreted from breaks in magnetic trends and vertical magnetic gradient features.
Unlike with lifting magnets, the purpose of magnetism for separating is not to anchor a load firmly, but to induce a motion into material (attraction for the ferrous and repulsion for the nonferrous), that has more to do with magnetic gradient and suitable frequency.
The researchers added two lasers to the setup, one atop j the other, such that their light would cross the magnetic gradient.
