Nanopatterned polymethylpentene substrates fabricated by injection molding for biophotonic applications

This paper reports the well-controlled replication of nanostructures with features sizes as small as 50nm on the surface of polymethylpentene (PMP) substrates by injection molding. A 2'' silicon wafer carrying the nanostructures served as exchangeable mold insert. This PMP injection molding process is aimed at developing a planar optical polymer waveguide platform for evanescent wave sensing. In particular we focus on disposable polymer optical biochips for the label-free detection of bio-molecules.
