일시: 2006년 7월 6일 (목요일) 오전 10:30
장소: 반도체물성연구소 세미나실 (104호)
연사: Dr. Yeo-Heung Yun
Dept. of Mechanical Engineering, Univ. of Cincinnati, OH, U.S.A.
제목: Nanotube Array Synthesis and Applications In Medicine
초록:
Highly aligned MWCNT (Multi-Walled Carbon Nanotube) has synthesized on the various substrates on the Si wafer and their effects are studied to understand the nature of CNT growth. Environmental scanning electron miscroscopy (ESEM), energy dispersive spectroscopy (EDS), high resolution transmission electron miscroscopy (HRTEM), and atomic force microscope (AFM) are used to analyze the CNT growth morphology.
Initial studies of cell-nanotube interaction were presented in this chapter. 3T3 fibroblast cells on glass substrates coated with chemically functionalized carbon nanotube and nanofiber materials were grown and exam the nanotube-fiberblast cell interaction.
Various CNTs biosensors are developed which include the their exceptional properties, the difficulties in processing nanoscale materials, and it also presents possibilities for building futuristic, and preliminary bio-devices for monitoring systems. Cyclic voltammetry (CV) with 6 mM K3Fe(CN)6 and Cl3Ru(NH3)6 in 1.0 M KNO3 solution is performed to analyze the redox behavior of the nanotube tower electrodes and showed ideal steady-state voltammetric behavior explained by radial diffusion with a high steady-state current density. Anti-immunoglobulin was immobilized on the nanotube electrodes, and electrochemical impedance spectroscopy (EIS) is done to monitor with the addition of mouse immunoglobulin. Electrochemical immunosensors as label-free method to detect angiogenic molecules and bone marker for understanding the cancer metabolisms and osteoporosis is described briefly in this dissertation too. This presentation discusses future cancer and osteoporosis sensor development based on the carbon nanotube array as the working electrode.
