Natural Channel

The influx of cations into vesicles mediated by a synthetic transporter is coupled to proton efflux and may be quantified by a pH-stat technique. The dependence of the transport upon cation type and concentration, upon transporter concentration, and upon temperature has been examined. The synthetic transporter is closely similar to the natural channel forming compound gramicidin, and significantly different from the carrier valinomycin, with respect to the variables examined. Keywords: ion transport, vesicle membrane, channel, gramicidin, transport mechanism.

Experimental Approaches

The modification of the inner nanopore wall by polymers is currently used to change the specific properties of the nanosystem. Among them, the polyethylene glycol (PEG) is the most used to prevent the fouling and ensure the wettability. However, its properties depend mainly on the chain structure that is very difficult to estimate inside this confined space. Combining experimental and simulation approaches, we provide an insight to the consequence of the PEG presence inside the nanopore on the nanopore properties. We show, in particular, that the cation type in the electrolyte, together with the type of electrolyte (water or urea), is at the origin of the ion transport modification in the nanopore.
