Open Access research with a European policy impact...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

Abstract

Several biological organisms are able to produce patterned and hierarchical biomineral structures. Diatoms, sponges and grasses deposit ornate biogenic silica structures under ambient conditions. These biological systems are able to selectively uptake, store and process soluble silicon (in an as yet unknown form) and mould it with great sophistication into biosilicas. Some aspects of the molecular mechanism(s) controlling biosilicification have recently been elucidated. In order to understand the interactions between these biomolecules and the biosilicas generated in various organisms and also to make use of any understanding so gained, in vitro experiments have been designed that make use of biomimetic analogues for developing bioinspired synthetic schemes for silica synthesis. The results obtained from bioinspired silicification investigations are hypothesised to arise from specific mode of actions of the organic additives and will be presented. Specifically, additives in bioinspired silicification act either as catalysts, aggregation promoting agents or structure-directing agents or more typically, exhibit a combination of these behaviours. Each of these effects will be discussed and representative examples given.
