An Amperometric Immunosensor for α-fetoprotein Based on Antibody Coated Nano ZrO2-Au-poly Lysine Composite Membrane Modified Electrode Yuanzhao Wu, Futao Hu, Ning Gan*, Jianguo Hou, Tianhua Li, Yuting Cao, Lei Zheng* Faculty of Materials Science and Chemical Engineering Ningbo University Ningbo 315211, China E-mail: gannging@nbu.edu.cn, nflab@163.com Keywords: Cyclic voltammetry (CV), zirconium dioxide nanoparticles, gold colloid, poly-Lysine (pLL), α-fetoprotein (AFP) Abstract.
Researchers have demonstrated that zirconia has a strong affinity for the phosphoric group and has been proved to be a fixed ideal material of biological molecules [10-11].
By combining the advantages of the MWNTs-DNA material and ZrO2-Au-pLL-antiAFP nano probes, the immunosensor with excellent sensitivity and selectivity to AFP was prepared successfully.

The joining technology was important for materials' development and excellent joining was an effective solution for simplifying product design and decreasing the cost.
Besides, Adding laser beam shielding gas removed light induced plasma, increased the absorption rate of materials to laser beam and decreased the loss of magnesium.

Tungesten Carbide-Cobalt is widely used as coating materials in the aerospace, gas turbibe and automotive industry.Heated coating particles impact upon the substrate at very high speed cause deformation to the substrate surface.Most of the application uses steel material as a substrate.The impact of particle creates small stress fields, which depend upon the state of the spraying material in the injector gun [2].The temperature of flame is between 2300°C and 3000°C [4].
Its complicated to analyze how single particle behave at the time of impact.This study considering substrate as a rigid material .The present work is divided into two parts.
The material data for Tungsten Carbide-Cobalt is taken from METCO/Perkin Elmer Materials Guide 2001 Diamalloy 2003[5], the average particle size being 45 micron.

Introduction Concerning electronic excitation, many important systems show anisotropy such as familiar layered materials like graphite[1] and BN[2], non-central symmetric semiconductor compounds such as GaN[3], superconductors such as YBaCuO[4] and MgB2[5].
Some nanostructures such as nano-tubes and nano-onions can be considered as roll-up versions of layered materials (Fig.1a), so the local anisotropy also changes with position inside the nano-structured material.
