Resistive Pulse Technique

Nanopores are emerging as powerful tools for the detection and identification of macromolecules in aqueous solution. In this review, we discuss the recent development of active and passive controls over molecular transport through nanopores with emphasis on biosensing applications. We give an overview of the solutions developed to enhance the sensitivity and specificity of the resistive-pulse technique based on biological and solid-state nanopores.

Mineral Oxide Surfaces

An extension has been made to Gouy-Stern-Grahame models of the double layer on mineral oxide surfaces.1 In this work and an earlier paper,2 the Stern isotherm is used for adsorption of p.d. ions at the surface. This is essentially an inversion of the modified Nernst equation given by Levine and Smith.3 The development of the surface charge and potential is considered by two different but related methods. Comprehensive calculations show that the zeta potential of oxide systems may be reasonably simulated with such models but the calculated surface charge is much less than that found experimentally. It is suggested that a model in which this surface charge is incorporated into a gel layer may be more appropriate.
