Abstract:
1. A microfluidic device, comprising: (a) at least one channel for conducting a fluid, said channel having an internal channel surface formed in a substrate; (b) a first polymer attached to the channel surface through photoinitiated grafting of a first monomer to selected regions of the channel surface; (c) a porous polymer monolith, comprising a second monomer attached to said first polymer in the selected regions in said channel through photoinitated grafting thereby bonding the monolith to the channel surface, wherein the first and second monomers may be the same or different; and (d) a polymer chain comprising a third monomer having a functional group, wherein said polymer chain is attached to a portion of the porous polymer monolith by photoinitiated grafting of said third monomer, wherein the third monomer is different from the second monomer.
