Fabrication of biomolecules self-assembled on Au nanodot array for bioelectronic device.

In the present study, an nano-platform composed of Au nanodot arrays on which biomolecules could be self-assembled was developed and investigated for a stable bioelectronic device platform. Au nanodot pattern was fabricated using a nanoporous alumina template. Two different biomolecules, a cytochrome c and a single strand DNA (ssDNA), were immobilized on the Au nanodot arrays.

Analysis of nanoscale protein film consisting of lactoferrin/11-MUA bilayers for bioelectronic device.

We fabricated and analyzed a nanoscale biofilm of human lactoferrin making use of 11-mercapto-undecanoic acid (11-MUA) as chemical linker. The fabrication of the bimolecular/organic hetero monolayer (lactoferrin/11-MUA) on gold substrate was confirmed with Raman spectroscopy. Cyclic voltammetry (CV) was carried out to observe the electrochemical properties of the nanoscaled biofilm under various pH conditions and at different time intervals.
