Surface Chemistry of Single Walled Carbon Nanotubes for Molecular Sensing
Huixin He, Rutgers University
Due to their large surface area as well as their distinctive optical and electrical properties, single-walled carbon nanotube (SWNT) has been widely used for extremely sensitive molecular detection in varies areas. However, to develop a sensing system for practical applications, selectivity is equally important as its sensitivity. My presentation will be focused on how to design and modify the surface of SWNTs for different sensing applications, including detection of cancer cells for early cancer diagnosis, detection of warfare agents for homeland security, nutrient iron ions in remote sea water and dust for environmental protection.
