Abstract
A method of making a set of metallic deposits includes injection molding a substrate, where a pattern of channels is in a surface of the substrate, applying a metallic layer on the surface, to form metallic deposits in the pattern, and removing a portion of the metallic layer, to expose a portion of the surface. The set of metallic deposits can form an electrode set for an electrochemical sensor strip.
Claims50
A method of making a set of metallic deposits, comprising:
- injection molding a substrate, wherein a pattern of channels is created in a surface of said substrate, and said pattern of channels comprises at least one channel and at least one island;
- forming a metallic layer on said surface, to form metallic deposits in said pattern;
- and
- removing a portion of said metallic layer, to expose at least a portion of said at least one island.
A set of metallic deposits, comprising:
- a pattern of channels in a surface of a substrate, and
- metallic deposits in said pattern,
- wherein portions of said surface are exposed, and
- said substrate comprises an injection moldable polymer.
22 The set of metallic deposits of claim 20, wherein said polymer is a thermoplastic polymer.
The set of metallic deposits of claim 22, wherein said polymer is a polycarbonate.
An electrode set, comprising:
- an electrode pattern in a surface of a substrate, and
- metallic deposits in said pattern,
- wherein said substrate comprises an injection moldable polymer.
A mold insert, comprising a metal,
- wherein a reverse electrode pattern is in a surface of said mold insert.
A set of metallic deposits, comprising:
- a pattern of channels in a surface of a substrate, and
- metallic deposits in said pattern,
- wherein portions of said surface are exposed, and
- said pattern of channels are formed by injection molding.
An electrode set, comprising:
- an electrode pattern in a surface of a substrate, and
- metallic deposits in said pattern,
- wherein said electrode pattern is formed by injection molding.
