Abstract A series of experiments on rats have been performed, to study the
effects of long time (50 days) exposure to electromagnetic fields of extremely
low frequency (ELF, i.e. less than 100 Hz) and amplitude (non thermal), testing
whether the metabolic processes would be affected. The background lies on recent
observations on the behaviour of isolated enzymes in vitro exposed to EFL
fields. In ... hiện toàn bộ
Abstract Background Magnetic Split-flow thin (SPLITT) fractionation is a newly
developed technique for separating magnetically susceptible particles. Particles
with different field-induced velocities can be separated into two fractions by
adjusting applied magnetic forces and flow-rates at inlets and outlets. Methods
Magnetic particles, Dynabeads, were used to test this new approach of
field-induc... hiện toàn bộ

The effects of weak magnetic and electromagnetic fields in biology have been
intensively studied on animals, microorganisms and humans, but comparably less
on plants. Perception mechanisms were attributed originally to ferrimagnetism,
but later discoveries required additional explanations like the "radical pair
mechanism" and the "Ion cyclotron resonance" (ICR), primarily considered by
Liboff. The... hiện toàn bộ

In recent years the visualization of biomagnetic measurement data by so-called
pseudo current density maps or Hosaka-Cohen (HC) transformations became popular.
The physical basis of these intuitive maps is clarified by means of analytically
solvable problems. Examples in magnetocardiography, magnetoencephalography and
magnetoneurography demonstrate the usefulness of this method. Hardware

Biotechnology applications of magnetic gels include biosensors, targeted drug
delivery, artificial muscles and magnetic buckles. These gels are produced by
incorporating magnetic materials in the polymer composites. A biocompatible
magnetic gel film has been synthesized using polyvinyl alcohol. The magnetic gel
was dried to generate a biocompatible magnetic film. Nanosized iron oxide
particles (γ-... hiện toàn bộ
Magnetic separation technology, using magnetic particles, is quick and easy
method for sensitive and reliable capture of specific proteins, genetic material
and other biomolecules. The technique offers an advantage in terms of subjecting
the analyte to very little mechanical stress compared to other methods.
Secondly, these methods are non-laborious, cheap and often highly scalable.
Moreover, tech... hiện toàn bộ
