SQUID magnetometers are most commonly used to measure the magnetic fields produced by laboratory samples, also for brain or heart activity (magnetoencephalography and magnetocardiography, respectively). Geophysical surveys use SQUIDs from time to time, but the logistics of cooling the SQUID are much more complicated than other magnetometers ...
Magnetic Immunoassay (MIA) is able to detect select molecules or pathogens through the use of a magnetically tagged antibody. Functioning in a way similar to that of an ELISA or Western Blot, a two-antibody binding process is used to determine concentrations of analytes. MIA uses antibodies that are coating a magnetic bead.
historically, used in human or animal experiments to measure and record data Long extension kymograph: historically, used in or human animal experiments to measure and record data Surface plasmon resonance: Label-free detection of molecule binding. Used to determine kinetic constants of the interaction (k a, k d, K D). Can also be used for ...
Simon Foner at MIT Lincoln Laboratory invented VSM in 1955 and reported it in 1959. [1] Also it was mentioned by G.W. Van Oosterhout [2] and by P.J Flanders in 1956. [3] A sample is first placed in a constant magnetic field and if the sample is magnetic it will align its magnetization with the external field.
Magnetoencephalography (MEG) is a functional neuroimaging technique for mapping brain activity by recording magnetic fields produced by electrical currents occurring naturally in the brain, using very sensitive magnetometers.

used for nasogastric suction (or at times introduction of food or drugs). video link: FNAC needles: used for fine needle aspiration of material from inside the body; used for diagnostic examinations of the cells hence obtained; video link: Trephine biopsy needle [4] used for taking a biopsy from a deep hard tissue like bone marrow (within a ...
The range of magnetometers based on piezoelectric resonators is mV/T (millivolt/Tesla), so higher responsivity is generally better. [5] Resolution refers to the smallest magnetic field a device can measure. The smaller the number, the more sensitive the device. The range of magnetometers based on piezoelectric resonator is a few nT (nanoTesla). [5]
