概要 We have developed nanometer-flat deoxyribonucleic acid (DNA)-featured solid thin films using a DNA source extracted from salmon sperm via the laser molecular beam deposition (LMBD) method under the high-vacuum condition. The DNA thin films formed by LMBD had molecular flatness with an average surface roughness of 7.4 nm. Although fragmentation due to the cleavage of the phosphate bonds was observed, quartz crystal microbalance (QCM) sensors fabricated with DNA thin films using LMBD showed higher methanol detection capability than sensors using DNA thin films fabricated by spin coating, indicating that LMBD-DNA thin films have a high potential for sensor applications.
