Abstract

A poly(methyl methacrylate) (PMMA) membrane having a highly porous, reticulated, 3-D structure suitable for lateral flow diagnostic applications is described. Also described is a method for producing a poly(methyl methacrylate) (PMMA) membrane that comprises the steps of mixing a suitable amount of PMMA, a solvent and a optionally one of either a co-solvent or a non-solvent to produce a solution, casting a thin film of the solution onto a support, and removal of the solvent from the solution to produce the PMMA membrane. A lateral flow diagnostic device comprising a highly porous PMMA membrane as a reaction membrane is also described.
