US 7,718,419 B2 · Microdevices having a preferential axis of magnetization and uses thereof

Abstract

This invention relates generally to the field of moiety or molecule isolation, detection and manipulation and library synthesis. In particular, the invention provides a microdevice, which microdevice comprises: a) a magnetizable substance; and b) a photorecognizable coding pattern, wherein said microdevice has a preferential axis of magnetization. Systems and methods for isolating, detecting and manipulating moieties and synthesizing libraries using the microdevices are also provided.

Claims26

Dependent claims

A microdevice which comprises:

a) a first layer of nonmagnetic material;
b) a photorecognizable coding pattern on said substrate;
and
c) a second layer comprising magnetic material,
wherein said microdevice has a longest linear dimension of not more than 500 microns and has a preferential axis of magnetization, and wherein an induced magnetization in its absolute magnitude along the preferential axis of magnetization of said microdevice is at least 20% more than induced magnetization of said microdevice along at least one other axis.
