Nanoporous metals obtained by dealloying and their application in biotechnology Video: https://tugraz.webex.com/meet/egbert.zojer Dealloying is a selective etching process, which removes the less noble component(s) from an alloy, resulting in a sponge-like nanoporous structure of the more noble component(s). Offering a very high surface-to-volume ratio, these 3-dimensional, free-standing structures, are promising candidates for a broad spectrum of applications. One particularly interesting topic is the immobilization of biomolecules at the conductive surface to create enzyme electrodes (e.g. 3rd generation biosensors). For this purpose, the metal surface can be modified by self-assembled monolayers (SAMs), offering functional groups that enable enzyme immobilization in a second step. This talk will give an introduction to the method of dealloying, followed by an overview of the collaborative research on the fabrication of enzyme electrodes, conducted by the TU Graz Institutes of Materials Physics and Biotechnology and Biochemical Engineering in the framework of the TU Graz Lead Project „Porous Materials @ Work“ |
