Electroanalytical applications have been found for determining some biomolecules recently, but the carbon nanotubes are only regarded as a kind of modified material to some traditional electrodes, such as, casting carbon nanotubes on Pt, Au and glassy carbon electrode or intercalating carbon nanotubes on graphite electrode.

值得注意的是在这些研究中，碳纳米管仅仅当作传统电极的修饰材料，比如，将碳纳米管涂在铂、金和玻碳电极上，或者将碳纳米管嵌入石墨电极表层中。

The PVA could help CNTs weltering the aquatic phase and enhance the stability of their dispersion. The PVA had bifunctional bridges, with hydrophilic groups jointed with the Fe2O3 film, and hydrophobic chains adhered to the surface of the carbon nanotubes, so the Fe2O3 were supported on the surface of the carbon nanotubes through the surfactant.

聚乙烯醇均匀吸附在碳纳米管表面，增强碳纳米管在水溶液中的分散，其疏水基团与碳纳米管以范德华力结合，其亲水基团与Fe2O3·nH2O结合，对碳纳米管有效负载Fe2O3起到了桥梁作用。

For the high affinity sites, binding constant decreases with the decrease of the alkyl chain lengh in the surfactants, but for the low affinity sites, binding constant increases and are not distinct when the alkyl chain is dedocyl. The binding sites are related to the alkyl chain lengh, not for the number of hydrophile groups and temperature.Isothermal titration calorimetry has been used to observe the enzyme-catalyzed hydrolysis reaction of urea.

对于高结合位点，结合常数随疏水碳链长度的减小而减小；对于低结合位点，结合常数随疏水碳链长度的减小而增大，相应的当碳链减小至C12时，低结合位点不明显，结合位点数可能只与碳链长度有关，随亲水头基和温度变化不明显。

It was shown by further research that the formed tungsten oxide had an obvious layer-like structure, where from outer to inner layer the valence of tungsten increased and the reduction degree decreased. The carbonization of W depended on the replacement of W atom at the center of the body-centered cubic by C atom and the minor adjustment of C atom position and the lattice parameters.

深入研究表明，氧化钨碳还原颗粒具有明显的层状结构，自外到内钨的化合价递增，还原程度降低；钨的碳化是碳原子替换体心立方钨晶胞的中心钨原子，然后碳原子转换到钨原子点阵间隙再经晶胞常数微调而形成。
