Claims22
A freestanding rod-shaped particle comprising 2 to 50 segments, wherein the particle has a generally circular cross-section along its length, wherein the segment transitions are generally perpendicular to said length, wherein the particle length is from 20 nm to 50 μm and the particle width is from 5 nm to 50 μm, and
- wherein at least one segment is comprised of a metal selected from the group consisting of:
- silver, gold, copper, nickel, palladium, platinum, cobalt, rhodium and iridium, and wherein the particle contains information regarding an associated material.
A freestanding segmented rod-shaped particle manufactured by a method including the deposition of a plurality of materials inside a template, the method of manufacturing the particle comprising:
- a) causing deposition of a first material into a pore of said template;
- b) causing deposition of a second material into said pore of said template, wherein the deposition of at least one of said first material and said second material is electrochemical deposition;
- and
- c) releasing said segmented particle from said template to provide a freestanding segmented particle having a length from 10 nm to 50 μm and a width from 5 nm to 50 μm, wherein said particle has a generally circular cross-section along its length, wherein the segment transitions are generally perpendicular to said length, and wherein the particle comprises 50 or fewer segments, and wherein at least one of said segments has a length of at least 10 nm, and wherein the particle contains information regarding an associated material.
A freestanding particle comprising 2 to 50 segments, wherein the particle length is from 20 nm to 50 μm, and the particle width is from 5 nm to 50 μm, and wherein at least one of said segments is comprised of a superparamagnetic compound.
A freestanding rod-shaped particle comprising 2 to 50 segments, wherein the particle has a generally circular cross-section along its length, wherein the segment transitions are generally perpendicular to said length, wherein the particle length is from 20 nm to 50 μm, and the particle width is from 5 mm to 50 nm,
- wherein at least one segment is comprised of a metal selected from the group consisting of:
- silver, gold, copper, nickel, palladium, platinum, cobalt, rhodium and iridium;
- and
- wherein the particle is an electronic device or a part of an electronic device.
