Microorganism-based Assemblies Of Luminescent Conjugated Polyelectrolytes

摘要

A novel approach was developed for the assembly of fluorescent conjugated polyelectrolytes into tubes on the micrometre scale of tunable length using fungi as living templates.rnThe development of self-assembled meso- and macroscopic materials is of current interest because of their unique structures and applications in photonics, electronics, catalysis, and sensors. However, the synthesis of self-assembled materials with controlled size on the nanometre or micrometre scale in all dimensions continues to be a challenge. In this regard, by integrating biology into materials research, it is possible to use well-ordered biomolecules as construction tools for the preparation of supramolecular materials on the nano- and micrometre scales. In nature, it is well known that many microorganisms can mediate metal ions for the production of inorganic materials, such as iron oxides by bacteria, siliceous materials by diatoms, and biogenic minerals by fungi.6'7 By learning from nature, recently, microorganisms including viruses, bacteria and fungi have been used as living templates for directing the synthesis of inorganic materials, such as gold nanoparticles, magnetic microstructures, and semiconducting nanowires. Microorganisms have several advantages as live templates for materials preparation. They are readily available, inexpensive and uniform in size.
