AI Contract Overview

The National Institute of Standards and Technology (NIST) is developing an advanced microfluidic platform designed to facilitate the high-throughput sorting and manipulation of magnetic particles and biomolecules. This innovative platform utilizes an array of switchable spin-valve elements that can be toggled between ferromagnetic "on" states, generating localized magnetic fields to trap and manipulate particles, and antiferromagnetic "off" states, which release the particles by eliminating the magnetic field. This capability allows precise control over magnetic particle movement and interaction, with the option to have the particles and traps either separated by a membrane or co-located on the same side. The design not only enables selective trapping and release but also allows external global magnetic fields to rotate the confined particles while they are held in place by the spin-valve elements. This technology has potential applications in biological and materials research where controlled manipulation of magnetic particles is crucial. The development is managed by NIST's Office of Technology Partnerships, with Susan K. Brinkman as the contract specialist contact, indicating ongoing work toward refining this platform and its practical applications in scientific and industrial fields.

This is not an announcement of a contract action or a grant. NIST DOCKET NUMBER: 04-016US Title: Microfluidic Platform of Arrayed Switchable Spin-Valve Elements for High-Throughput Sorting and Manipulation of Magetic Particles and Biomelecules Description: The invention presents a microfluidic platform that incorporates an array of spin-valve elements to selectively trap, manipulate and release magnetic particles with high throughput and specificity. The array of spin-valve elements can exist in a ferromagnetic - on state, thereby acting like mini bar magnets with local magnetic fields. The magnetic field gradients provide the trapping field to confine the magnetic particles. The spin-valve element can be turned to the antiferromagnetic - off state where they no longer produce a local magnetic field. In the absence of the local magnetic field, the magnetic particles are released from the trap. The platform consists of a membrane that can separate the traps from the magnetic particle fluid, or it is possible to have the magnetic particle fluid on the same side of the traps. The - on/off magnetic characteristic of these elements make it possible to apply an external global magnetic field to rotate the magnetic particles while they are confined by the spin-valve elements.
