Duration:<\/strong> September 2025 \u2013 August 2029 (48 months)<\/p>\n\n\n\n

Overview<\/h6>\n\n\n\n

STRUCTURE focuses on the development of novel bottom-up assembly methods for hierarchical inorganic materials. By drawing inspiration from the biomineralization processes of diatoms\u2014microscopic organisms capable of creating complex, highly ordered silica structures\u2014this research aims to replicate these pathways in vitro<\/em>.<\/p>\n\n\n\n

The project employs advanced soft matter model systems, including lipid membranes and giant unilamellar vesicles (GUVs), to guide the synthesis of inorganic materials. By integrating biomolecules associated with diatom biomineralization, such as specialized peptides, the research seeks to achieve precise control over the morphology and spatial organization of silica, as well as metals, metal oxides, and semiconductors.<\/p>\n\n\n\n

Research Objectives<\/h6>\n\n\n\n

The core ambition of STRUCTURE is to leverage lipid phase separation and membrane dynamics as a new strategy for material modelling. This approach addresses current limitations in synthetic chemistry regarding complexity and functionality, providing a framework for:<\/p>\n\n\n\n

    \n
  • Hierarchical Control:<\/strong> Achieving nanostructure and mesostructure precision through membrane-guided growth.<\/li>\n\n\n\n
  • Biomimetic Synthesis:<\/strong> Exploring phase behavior in lipid bilayers to direct the organization of inorganic precursors.<\/li>\n\n\n\n
  • Real-time Monitoring:<\/strong> Using advanced characterization techniques\u2014including total internal reflection fluorescence (TIRF) microscopy, scanning electron microscopy (SEM), and solid-state nuclear magnetic resonance (NMR) spectroscopy to observe the biomineralization process as it occurs.<\/li>\n<\/ul>\n\n\n\n
    Impact<\/h6>\n\n\n\n

    By elucidating the natural principles governing diatom biomineralisation, the STRUCTURE aims to push the boundaries of synthetic material design, offering new routes for the creation of functional, highly structured materials with tailored properties for advanced photonic and electronic applications.<\/p>\n\n\n\n
