N2 - The adsorption behavior of mutant ferritins, which have 24 carbonaceous material binding peptides, onto a polymer-coated SiO 2 substrate was studied. A SiO 2 surface was modified by poly(L-lysine) (PLL) and poly(ethylene glycol) (PEG) and the spin-coating technique was used. The state of the ferritin array on PLL-coated SiO 2 was random adsorption, however, many adjacent domains of hexagonal close-packed ferritin arrays about 100-200nm in diameter were formed on PEG-coated SiO 2. PEG and the protein portion of ferritin were removed by heat treatment. The fabricated dispersed hexagonal close packed nanodot arrays on SiO 2 substrates can be applied to semiconductor devices.
