Afm Tips

Using metal-coated atomic force microscope (AFM) tips and single-walled carbon nanotube (SWNT) BuckyPaper films, the authors have successfully explored the feasibility of electro-machining (EM) at the nanometer scale. Highly ordered pyrolytic graphite (HOPG) and thin metal films were used as a substrate (workpiece) and metal-coated (Cr/Au) Si AFM tips and BuckyPaper films were used as electrodes. A negative voltage pulse was applied to the AFM tip to fabricate holes as small as 30 nm in diameter on the HOPG surface. Using SWNT BuckyPaper films, the submicron holes were fabricated on a metal surface, demonstrating that SWNTs can work as electrodes.

Pyrolytic Graphite Electrode

A fast and sensitive voltammetric method has been proposed for the determination of salbutamol at single-walled-carbon-nanotube-modified edge-plane pyrolytic graphite electrode (SWNT/EPPGE) in human urine. The electrochemical response of salbutamol was determined by square wave voltammetry (SWV) in phosphate buffer solution (PBS) at physiological pH 7.2. The modified electrode showed improved voltammetric response towards the oxidation of salbutamol, and a well-defined anodic peak was observed at~600 mV with enhanced peak current in comparison to the bare electrode. Linear calibration plot using SWNT/EPPGE was obtained in the concentration range of 50 to 2500 ngml-1with sensitivity and detection limit of 2.15 nA/ngml-1and 4.31 ngml-1, respectively. The developed method has been successfully applied for the determination of salbutamol in commercial preparations and human body fluids. Fast analysis of salbutamol in human urine makes the proposed method of great interest for doping control purposes at the site of competitive games.
