Paper-based biosensor
Paper has emerged as a focus area for researchers developing innovative techniques for printed basic electronics components. Electronic paper displays are already a commercial reality and prototypes of things like paper batteries are under development. In these applications, researchers transfer thin films, nano particles or other nanostructures onto the desired substrate via various processes. Another area where paper could lead to low-cost innovative devices and applications is lab-on-a-chip technology. Currently, these micro fluidic devices are fairly expensive due to their lithography-based fabrication process with channels patterned in glass or plastic and tiny pumps and valves directing the flow of fluids. Inexpensive paper-based sensing kits already play an important role in ready-to-use diagnostics. Researchers have even managed to create an inexpensive micro fluidic platform on hydrophobic paper with laser treatments. In a further advance, scientists have now fabricated a paper-based metamaterial device which can be potentially utilized for quantitative analysis in biochemical sensing applications.
In this device, paper acts as the dielectric substrate providing both support and a material to sample and embed analytes which then modulate the resonance of the split-ring resonators that compose the metamaterials. The team has patterned paper substrates through selective deposition of a target material (gold) through a 500-nm-thick silicon nitride film micro stencil-based shadow mask. Similarly to what had previously been done for silk, the micro stencils were carefully attached to the paper substrates in contact mode. A thin layer of 150-nm-thick gold was then sprayed on the paper substrates using electron beam evaporation. Since the surface roughness of the paper substrate affects the pattern quality (including both the minimum transferable line width and sharpness), the researchers used photo paper with a surface roughness of less than 18 nm.
