Project Description

The transportation of ions through single-walled nanotubes (SWNTs) was studied using a twelve-welled device, G22. Positive and negative voltages were applied through the SWNTs, and the current was monitored to look for pore-blocking events. Cations from NaCl were tested for their ionic mobility. The data were then analyzed to determine how much current was blocked and how long the ions stayed in the nanotube. Data obtained from previous trials with choline chloride at various pH levels show that ionic mobility (μ) is dependent on hydrogen ion concentration, [H+]. The data obtained for NaCl during summer fellows supports the consistent with the data acquired for choline chloride.
