Abstract

Ion and water transport through biological membranes by osmosis is essential in many biological processes and the complex nature of biological pores and channels involved in these processes is not fully understood. We are developing simplified robust models of ion channels based on smooth, narrow and hydrophobic pores of carbon nanotubes. Incorporation of these pores into liposomes gives us a convenient system to study osmotically-induced transport using dynamic light scattering. We will present our measurements of the transport of charged and uncharged chemical species through the carbon nanotube pores and also discuss the role of the charges at the nanotube pore ends in regulating the ion transport selectivity.
