Multifunctional Protein-Enabled Patterning on Arrayed Ferroelectric Materials
This study demonstrates a biological route to programming
well-defined
protein-inorganic interfaces with an arrayed geometry via modular
peptide tag technology. To illustrate this concept, we designed a
model multifunctional fusion protein, which simultaneously displays
a maltose-binding protein (MBP), a green fluorescence protein (GFPuv)
and an inorganic-binding peptide (AgBP2C). The fused combinatorially
selected AgBP2C tag controls and site-directs the multifunctional
fusion protein to immobilize on silver nanoparticle arrays that are
fabricated on specific domain surfaces of ferroelectric LiNbO<sub>3</sub> via photochemical deposition and in situ synthesis. Our combined
peptide-assisted biological and ferroelectric lithography approach
offers modular design and versatility in tailoring surface reactivity
for fabrication of nanoscale devices in environmentally benign conditions
