Abstract:
1. A method of forming a microscopic structure of a material, the method comprising: obtaining a solution comprising the material, wherein the material comprises a metal; depositing a bonding layer on an inner wall of a capillary, wherein the capillary has an inner dimension that is smaller than about 300 micrometers; establishing a flowing stream of a colloidal suspension of particles within the capillary; maintaining the flowing stream of the colloidal suspension of particles until a layer of particles is built up on the bonding layer; establishing a flowing stream of the solution in the capillary; and maintaining the flowing stream of the solution to deposit material on the layer of particles until a layer of the material is built up along the inner wall of the capillary, thereby forming a microscopic structure.
