Polymerization‐Induced Self‐Assembly: An Emerging Tool for Generating Polymer‐Based Biohybrid Nanostructures

Abstract The combination of biomolecules and synthetic polymers provides an easy access to utilize advantages from both the synthetic world and nature. This is not only important for the development of novel innovative materials, but also promotes the application of biomolecules in various fields including medicine, catalysis, and water treatment, etc. Due to the rapid progress in synthesis strategies for polymer nanomaterials and deepened understanding of biomolecules’ structures and functions, the construction of advanced polymer‐based biohybrid nanostructures (PBBNs) becomes prospective and attainable. Polymerization‐induced self‐assembly (PISA), as an efficient and versatile technique in obtaining polymeric nano‐objects at high concentrations, has demonstrated to be an attractive alternative to existing self‐assembly procedures. Those advantages induce the focus on the fabrication of PBBNs via the PISA technique. In this review, current preparation strategies are illustrated based on the PISA technique for achieving various PBBNs, including grafting‐from and grafting‐through methods, as well as encapsulation of biomolecules during and subsequent to the PISA process. Finally, advantages and drawbacks are discussed in the fabrication of PBBNs via the PISA technique and obstacles are identified that need to be overcome to enable commercial application.
