ABSTRACT

Nano-bio interfaces play a significant role in assay device design and performance, here we study the use of a combined plasmonic and ferroelectric active substrate design for protein assemblies on a plasmon active array. We demonstrate that biotinylation and protein assemblies can be made on metal nanoparticles patterned on ferroelectric substrates. These results in turn demonstrate that ferroelectric substrates combined with active plasmonics is potentially applicable as substrates for biological assays.
