Claim 17:
18. A method of modifying a deformable substrate, the method comprising:
depositing a deformable substrate on a glass substrate;
depositing a sessile liquid droplet comprising a plurality of nanoparticles on a first surface of the deformable substrate, the sessile liquid droplet forming a deformed region in the first surface of the deformable substrate, the deformed region comprising a recess and a perimeter rim, the recess extending toward a second surface of the deformable substrate, and the perimeter rim extending away from the second surface of the deformable substrate; and
curing the deformable substrate, thereby increasing an elastic modulus of the deformable substrate such that upon removal of the sessile liquid droplet, the deformed region remains in the first surface of the deformable substrate and at least a portion of the plurality of nanoparticles are embedded in the perimeter rim of the deformed region of the deformable substrate, thereby forming an angular filter in the perimeter rim of the deformed region of the deformable substrate.
