1. A method for forming an optical disc, comprising:forming a first reflective layer over a substrate such that there is at least a first portion without the first reflective layer; forming a second reflective layer on a second portion of a cap; and assembling the substrate and cap so that the substrate and cap are parallel along a first direction and the first portion and second portion are aligned along a second direction perpendicular to the first direction such that the second portion of the cap covers the first portion without the first reflective layer. 2. The method of claim 1, wherein the first reflective layer is formed over the substrate and a portion is removed.3. The method of claim 1, wherein the first reflective layer is patterned over the substrate so that it is provided on the substrate with the first portion lacking.4. The method of claim 1, further comprising forming a capture layer over the first portion, the capture layer adapted to receive a biological material for capturing a reporter introduced into a volume between the first and second portions.5. The method of claim 1, further comprising providing a channel layer between the substrate and cap, the channel layer having a pattern cut out, such that when the substrate, cap, and channel layer are assembled, the pattern in the channel layer defines a fluidic channel in the optical disc.6. The method of claim 5, further comprising forming an opening in the cap over a portion of the fluidic channel.
