ORIENTED LOADING SYSTEMS AND METHOD FOR ORIENTING A PARTICLE LOADED IN A WELL

摘要

An oriented loading system is provided. The oriented loading system includes a substrate, a plurality of wells formed in the substrate, each well having a bottom and sidewalls, a plurality of particles loaded in the wells, wherein the particle comprises a core structure and an inner layer comprising magnetic material partially covering the core structure such that a part of the core structure uncovered by the inner layer is exposed, and a metal layer comprising magnetic material deposited partially in the sidewalls of the wells, wherein the inner layer is attracted by the metal layer such that the exposed core structure is oriented towards the bottom of the well or the inner layer is oriented towards the bottom of the well.

1. An oriented loading system, comprising:
a substrate; a plurality of wells formed in the substrate, each well having a bottom and sidewalls, the sidewalls having an upper part and a lower part; a plurality of particles loaded in the wells, wherein the particle comprises a core structure and an inner layer comprising magnetic material partially covering the core structure, or further an outer layer formed over the inner layer, wherein a part of the core structure uncovered by the inner layer is exposed or is further covered by a coating layer; and a metal layer comprising magnetic material deposited partially in the sidewalls of the wells, wherein the inner layer is attracted by the metal layer such that the exposed core structure or the coating layer, or the inner layer or the outer layer becomes a bottom side of the particle oriented towards the bottom of the well.
