Abstract:
1. A method of fabricating a biosensor chip, comprising: providing a device including a machine body defining a receiving space, a vacuumed chamber mounted in the receiving space, and a microwave emitting unit mounted on the machine body and corresponding to the vacuumed chamber; forming at least one metallic layer on a transparent substrate to form a composite member; disposing the composite member in the vacuumed chamber, and introducing a gas into the vacuumed chamber; applying microwave energy from the microwave emitting unit to the gas to produce a microwave plasma of the gas within the vacuumed chamber, and causing the microwave plasma to interact with the at least one metallic layer so that the at least one metallic layer is melted and formed into a plurality of metallic nanoparticles that are spaced apart from each other and are embedded partially into the transparent substrate and that expose partially the surface of the transparent substrate; and disposing a receptor at the surface of the transparent substrate that is exposed among the metallic nanoparticles.
