MagArray Technology

MagArray GMR Chip

When assay platforms rely on the detection of optical labels, they are at risk of optical interference in biological matrices. There is too much room for error and uncertainty. There is also a limit to the assay sensitivity. The MagArray technology overcomes these concerns with an assay format based on the use of magnets to detect magnetic labels. The low-cost, chip-based platform is capable of simultaneously detecting dozens of analytes in as little as 10 minutes.

Developed by Stanford professors who adapted magnetic sensing technology from the computer disk drive industry, the MagArray system is several hundred times more sensitive than systems using optical readers. There are other advantages to this innovative system:

  • It can accommodate virtually any sample type, including blood, plasma, serum, urine, and saliva. (No extra steps are required to process whole blood samples.)
  • It uses chips with up to 80 sensors that can be individually printed with a capture reagent. That means reference, control, and unique biomarker sensors can all be printed on one chip, and in multiple replicates to provide internal quality control.
  • The technology provides exceptional sensitivity without sacrificing reproducibility.
  • The system is rugged, easy to use, and easy to maintain.
