Improving the affinity of silicon surface for biosensor application: The interaction between multiwall carbon nanotube (MWCNT) and chitosan (CS)

Previous study show the preparation, characterization and physical properties of carbon nanotube (CNT) and chitosan (CS). Multi-Wall CNT (MWCNT) and chitosan is utilized on the silicon surface in this studies. Functionalized of Multi Wall Carbon Nanotubes (MWCNTs) were demonstrated using the nitric acid (HNO3) oxidation technique to remove impurities. In this studies, the interaction between CS-MWCNT was investigated and explained according to the UV-VIS result. The range of the wavelength obtained from the UV-Vis data is 200-700nm. The hybrid form of CS-MWCNT proves to be more promising as a surface for biosensing application.
