Developing synthetic conical nanopores for biosensing applications
Abstract
In this review we bring together recent results from our group focused towards the development of biosensors from single conically-shaped artificial nanopores. The nanopores, used in the work presented here, were prepared using the track-etch process. The fabrication of track-etched conical nanopores has been optimized to allow for single nanopores with reproducible dimensions to be prepared. We have also demonstrated techniques that allow for easy and controllable manipulation of nanopore geometry (e.g., cone angle). We will consider the ion transport properties of the conical nanopores and factors that affect these properties. Methods for introducing functions that mimic biological
