The long-dreamed-of capability of monitoring the molecular machinery in living systems has
not been realized yet, mainly due to the technical limitations of current sensing technologies …

Today's magnetic-field sensors are not capable of making measurements with both high
spatial resolution and good field sensitivity. For example, magnetic force microscopy allows …

We review stationary and mobile systems that are used for the nondestructive evaluation of
room temperature objects and are based on superconducting quantum interference devices …

We experimentally demonstrate that one-dimensional Bose-Einstein condensates brought
close to microfabricated wires on an atom chip are a very sensitive sensor for magnetic and …

The ability of pigeons to sense geomagnetic fields has been conclusively established
despite a notable lack of determination of the underlying biophysical mechanisms. Quasi …

Magnetic microparticles or “beads” are used in a variety of research applications from cell
sorting through to optical force traction microscopy. The magnetic properties of such …

Superconducting quantum interference devices (SQUIDs) are accepted as one of the
highest magnetic field sensitive probes. There are increasing demands to image local …

The use of a magnetometer or gradiometer as a quantitative instrument requires the proper
calibration of the output voltage as a measure of the magnetic field. The methods used to …

Visualizing magnetic fields is essential for studying the operation of electromagnetic systems
and devices that use permanent magnets or magnetic particles. However, commercial …

We report the application of a scanning high-T c SQUID (superconducting quantum
interference device) microscope with a ferromagnetic flux guide for the nondestructive …
