Micro/Nanofabrication, Assembly, and Actuation Based on Microorganisms: Recent Advances and Perspectives

Microorganisms become new sources for fabricating intricate micro/nano structures via bottom‐up approaches. Produced from nature, microorganism biotemplates exhibit unique structural and material features over thousands of years of revolution. They are considerably superior and cost‐effective for fabricating complex and heterogeneous structures when compared to other micro/nanofabrication techniques. Herein, the recent advances in biologically driven micro/nanofabrication, assembly, and actuation based on microorganisms are consolidated. Detailed development and recent advances of micro/nanoparticle fabrication, their ordered assembly, and controlled actuation properties, as well as certain typical engineering application examples, are mainly involved. The developing perspectives and challenges of microorganism‐based micro/nanofabrication are also discussed, aiming to inspire the relevant researches and promote the development in this field.
