Abstract

original image

Treatment of amorphous diphenylalanine thin film at high temperatures as 150 °C with aniline vapor under anhydrous condition results in the formation of vertically well-aligned nanowires. By combining the high-temperature aniline vapor aging method with a simple soft-lithographic technique, we could fabricate a micro-scale pattern of vertically-grown peptide nanowires.
