Abstract:
1. A microdevice, which microdevice comprises: a) a magnetizable substance; b) a photorecognizable coding pattern, wherein said microdevice has a preferential axis of magnetization,and wherein an induced magnetization in its absolute magnitude along the preferential axis of the magnetization of said microdevice is at least 20% more than an induced magnetization of said microdevice along at least one other axis, wherein said microdevice has a thin rectangular shape with the preferential axis of the magnetization substantially in the direction of the length of the microdevice, and c) a binding partner that is capable of binding to a moiety on a surface of the microdevice.
