The aim of the proposed research project is the development of a novel method for the holographic patterning of phototactic microalgae, which are further converted into multiscale hybrid structural and functional materials. The phototactic microalgae (Prophyridium pupureum) will be inoculated in a specially designed nutrient gel, which allows the photostimulated movement through secretion of exopolysaccharides. A custom-designed optical system will be developed to project a transmission hologram into the microalgae inoculated nutrient gel. The holographically patterned microalgae templates will be converted into the corresponding inorganic hybrid functional materials using “soft” chemical sol-gel routes. This contactless patterning with light (hologram) exploiting the phototactic properties of specific microalgae represents a novel and particularly versatile approach for the fabrication of multiscale bioorganic/ inorganic hybrid materials. The realisable multiscale patterning method via holographic patterning of microorganisms in combination with inorganic phase formation has an enormous potential to be a novel key technology for the fabrication of complex, structured materials.

本研究的目的是开发一种新的光致微藻全息图像化方法，并将其进一步转化为多尺度混合结构和功能材料。将光致微藻（Prophyridium pupureum）接种在一种特殊设计的营养凝胶中，这种营养凝胶可以通过分泌外多糖来进行光刺激运动。将开发一个定制设计的光学系统，将透射全息图投射到接种了微藻的营养凝胶中。利用“软”化学溶胶-凝胶途径将全息图型微藻模板转化为相应的无机杂化功能材料。这种利用特定微藻的光致性的非接触模式（全息图）代表了一种制造多尺度生物有机/无机杂化材料的新颖和特别通用的方法。结合无机相形成的微生物全息图谱的可实现的多尺度图谱方法具有巨大的潜力，成为制造复杂结构材料的一项新的关键技术。
