In industry, enzymes are often immobilized to generate more stable enzyme preparations that are easier to store, handle, and recycle for repetitive use. Traditionally, enzymes are bound to inorganic carrier materials, which requires caseto-case optimization and incurs additional labor and costs. Therefore, with the advent of rational protein design strategies as part of bottom-up synthetic biology approaches, numerous immobilization methods have been developed that enable the one-step production and immobilization of enzymes onto biogenic carrier materials often directly within the production host, which we here refer to as in vivo immobilization. As a result, nano-to micro-meter-sized functionalized biomaterials, or biologically produced enzyme immobilizates, are obtained that can directly be used for synthetic purposes. In this Perspective, we provide an overview over established and recently emerging in vivo enzyme immobilization methods, with special emphasis on their applicability for (industrial) biocatalysis. For each approach, we present fundamental working principles as well as advantages and limitations guiding future research avenues toward sustainable applications in the bioindustry.

Biological structures achieve remarkable material performance owing to naturally assembled structures that extend from the molecular to macro‐scale. Synergy among constituents of various length scales yields lightweight, hierarchically structured materials with properties superior to those of individual components. To replicate nature's ingenuity, this work emulates the cylindrical core‐shell structure found in osteons and bamboo, utilizing Halloysite Nanotubes (HNTs) and Glass Fibers (GFs) in a semi‐crystalline polymer matrix. HNTs are environmentally friendly, naturally occurring tubular aluminosilicates with high aspect ratios, large lumen volumes, and low cost, and are readily dispersible in polymer matrices. Here, hierarchical reinforcement is achieved through controlled electrostatic assembly of HNTs onto GFs and subsequent trans‐crystallization‐encapsulation. This cylindrical core‐shell architecture yields composites with exceptional mechanical performance, superior thermal management (insulation/stability), improved industrial processability, and reduced flame propagation speed. Compared to the current industrial composite substitute for metallic structural components, the hybrid composites exhibit a remarkable 84% increase in impact strength, 27% increase in specific tensile strength, 56% increase in tensile toughness, and 30% in specific flexural strength, accompanied by a 20% weight reduction and a 255% increase in processability (melt‐flow index). This scalable assembly strategy marks a cornerstone in lightweight multifunctional materials development, to conquer future sustainability targets.
