NED-AM
Atomic Magnetometer
We have performed the first measurement of cancer cells in an atomic magnetometer (developed at The Sandia National Laboratories). This method allows for fast data acquisition, with no radiation required, and only bound nanoparticles are detected. As with the SQUID system, tissue, bone, and other media are transparent. The sensitivity of this detection method is unprecedented. With the current SQUID system, the noise is 2000 fT/√Hz, allowing for the detection of ~100,000 breast cancer cells. However, with the current atomic magnetometer system, the noise is only 15 fT/√Hz, allowing detection of ~750 breast cancer cells. This high sensitivity allows us to detect cancer cells in biopsy samples, histochemistry slices, and small animals with a high degree of sensitivity.
