Direct Laser Patterning of Conductive Wires on Three-Dimensional Polymeric Microstructures

We show that silver lines patterned on a substrate with multiphoton absorption can be rendered electrically conductive using electroless enhancement with copper. We demonstrate that this technique can be used to create metallic features on three-dimensional polymeric structures that have been fabricated with multiphoton absorption polymerization. This method makes it possible to use multiphoton absorption to create complete metal/polymer hybrid microstructures with a single fabrication setup.
