 报告内容简介：

We have been developing electroanalytical technique and chemical sensors by using sputter deposited nanocarbon materials and metal oxide. The nanocarbon films formed by electron cyclotron resonance (ECR) or unbalanced magnetron(UBM) sputtering techniques show wide potential window because of hybrid structure of sp² and sp³ bonds and low capacitive current due to very flat surface .These films have been applied for detecting various molecules and ions including DNAs, neurotransmitters and heavy metal ions. We fabricated fluorinated nanocarbon (F-nanocarbon) film by CF₄ plasma treatment and applied it to detect lipophilic antioxidant such as Vitamin E quantitatively in bicontinuous microemulsions(BMEs). Recently, we also developed metal NPs embedded carbon film electrodes by co-sputtering of metal and carbon. Compared with NPs modified electrodes fabricated by electrodeposited or physical adsorption processes, the metal NPs embedded carbon film electrode shows much longer stability because of tight carbon matrix. The AuNPs embedded carbon film can be successfully applied to detect As(III) and Se(IV) ions in the water samples below 10 ppb.The Ni/Cu nanoparticle alloy (Nanoalloy) embedded carbon film was formed by co-sputtering of carbon, Ni and Cu. This film shows high electrocatalytic activity for sugars and excellent stability.
