Stable, nanometer-thick oxygen-containing plasma polymer films suited for enhanced biosensing

Popis výsledku v původním jazyce

Stable surface functionalization is required in many applications such as in biosensing. For this purpose, hydrocarbon-based plasma polymer films (PPFs) were investigated by controlling cross-linking and film structure at the nanoscale, while functional groups were incorporated using a CO2/C2H4 low pressure plasma. In particular, an oxygen-rich termination layer of 1 nm (top layer) was gradually deposited onto a more cross-linked PPF (base layer) with varying thickness (&lt;20 nm) yielding highly stable yet functional a-C:H:O films as compared to conventional oxygen-rich PPFs. Such stabilized nano-layers provided a homogeneous functionalization of Au-coated (flat) biochips as used for immunosensing as well as of nanostructured Au-coated surfaces explored for enhanced biosensing. The used periodic grating coated by the highly stable a-C:H:O nano-layer can be adjusted to the required environmental refractive index range yielding a distinct sensitivity enhancement for biosensing.
