The use of nanoparticles as labels in biomolecular detection in place of conventional
molecular fluorophores has led to improvements in sensitivity, selectivity, and multiplexing …

Less than thirty years after the giant magnetoresistance (GMR) effect was described, GMR
sensors are the preferred choice in many applications demanding the measurement of low …

A laser-based atomic magnetometer (LBAM) apparatus measures magnetic fields,
comprising: a plurality of polarization detector cells to detect magnetic fields; a laser source …

Precision measurement of magnetic fields is at the heart of many important analytic
techniques in materials, geology, biology, medicine, security, space, and the physical …

Remote and non-invasive tracking of a moving magnetic object based on an atomic
magnetometer has been developed recently. The sensitivity of atomic magnetometers is …

In this work, a colossal enhancement of strain sensitivities through the push-pull deformation
method in interferometry is reported for the first time. For the demonstration of the new …

An InSb thin-film linear micro-Hall sensor array of eight sensors, each with a sensitivity of 10
nT/Hz/sup 1/2/was developed for biomedical applications. The individual Hall sensors had …

The authors demonstrate the detection of magnetic particles carried by water in a continuous
flow using an atomic magnetic gradiometer. Studies on three types of magnetic particles are …

Cardiac Troponin I (cTnI) functionalized immunomagnetic beads in lateral flow membrane
was measured to analyze the analyte kinetics of mass-transport and antibody–antigen …

We report the detection of nuclear magnetic resonance (NMR) using an anisotropic
magnetoresistive (AMR) sensor. A “remote-detection” arrangement was used in which …
