Abstract:
1. A method for generating a patterned soft substrate, the method comprising providing a base layer; depositing a sacrificial polymer on the base layer, thereby generating a sacrificial polymer layer; depositing a photoresist onto the sacrificial polymer layer, thereby generating a photoresist layer; placing a mask comprising a pattern on top of the photoresist layer and exposing the photoresist layer to electromagnetic radiation, thereby generating a patterned photoresist complementary mask comprising the complement of the pattern of the mask; releasing the patterned photoresist complementary mask from the sacrificial polymer layer; placing the patterned photoresist complementary mask onto a soft substrate such that the patterned photoresist complementary mask makes conformal contact with the soft substrate; and functionalizing the portion of the soft substrate that is exposed by the pattern in the patterned photoresist complementary mask by depositing a linker molecule and a biopolymer onto the soft substrate, wherein the linker molecule associates with the biopolymer and the soft substrate to attach the biopolymer to the portion of the soft substrate exposed by the pattern; thereby generating the patterned soft substrate.
