Abstract
Self-organization offer cost-efficient and easily scalable way to nanopattern polymer surfaces for various applications ranging from medical use to sensing applications. For example poly-L-lactic acid can be modified either by metal sputtering and/or plasma discharge to form ripple-like structures after annealing with size and regularity highly dependent on processing variables. Such samples have enhanced biocompatibility and as such they are promising substrates for use as various implants. Another example is annealing of polyethersulfone film modified by metal sputtering that causes coalescence of metal layer into separated metal nanoclusters. This structure exhibit localized surface Plasmon resonance, which can be used for example in Surface enhanced Raman spectroscopy.
