Title: PRODUCING A SEPARATION MEDIUM USING GRAYSCALE MASK
Abstract:
Provided are methods for producing a separation medium, where the method includes exposing a separation medium precursor solution to light from a light source through a photomask that includes a region with varied light transmittance to produce the separation medium. Systems that find use in performing the methods, microfluidic devices that include the separation medium, as well as methods of using the microfluidic devices, are also provided. Embodiments of the present disclosure find use in a variety of different applications, including detecting whether an analyte is present in a fluid sample.
