Outline of Final Research Achievements

The purpose of this study is to fabricate the hydrocarbon (HC) gas sensor by biomimetic nanocarbon structures. The cuttlebone is known to control adsorption/desorption by the unique three dimensional (3-D) structure for maintaining the buoyancy. First, we evaluated why the cuttlebone is uniquely form 3-D structures. We modified two different human cells known to grow only two dimension by oxygen atmospheric-pressure plasma. The change in actin filament growth and termination induced by the indirect treatment of oxygen plasma would change the cell growth characteristics from two to three dimensions. Next, we fabricated nanocarbon structures with different grain sizes and spacing to evaluate the sensitivity of HC detection and the molecular weight differentiation. The sensitivity of HC detection was promoted by reducing the nanocarbon structure spacing but the repeatability of the gas sensor requires adequate spacing to promote desorption of the HC.
