For bridging the gap between biological and synthetic materials, the fusion of Metal-Organic Frameworks (MOFs) with biological entities has emerged as a revolutionary strategy in functional materials. In this context, our study introduces a novel structure wherein Bovine Serum Albumin (BSA), a robust and versatile protein, encapsulates zeolitic imidazolate framework-8 (ZIF-8), forming a protein-caged MOF. Highlighting the advantages of this innovative design, the protein-encapsulation enhances the stability and dispersity of ZIF-8, and aids in the synthesis of smaller-sized nanoparticles, crucial for size-impact performance applications. Additionally, the BSA-caged ZIF-8 structure showcases potential in drug delivery applications, especially in the controlled delivery of chemotherapeutic drugs. The study thus elucidates the multifaceted applicability of this novel structure, marking a significant stride in the convergence of biological and synthetic materials.

The efficient immobilization of redox mediators remains a major challenge in the design of mediated enzyme electrode platforms. In addition to stability, the ability of the redox-active material to mediate electron transfer from the active-site buried enzymes, such as flavin adenine dinucleotide-dependent glucose dehydrogenase (FADGDH) and lactate oxidase (LOx), is also crucial. Conventional immobilization techniques can be synthetically challenging, and immobilized mediators often exhibit limited durability, particularly in continuous operation.

Metal-organic frameworks (MOFs) hold considerable promise for environmental remediation owing to their exceptional performance and distinctive structure. Nonetheless, the practical implementation of MOFs encounters persistent technical hurdles, notably susceptibility to loss, challenging recovery, and potential environmental toxicity arising from the fragility, insolubility, and poor processability of MOFs. MOF-based three-dimensional macrostructures (3DMs) inherit the advantageous attributes of the original MOFs, such as ultra-high specific surface area, tunable pore size, and customizable structure, while also incorporating the intriguing characteristics of bulk materials, including hierarchical structure, facile manipulation, and structural flexibility.

New carbon-based materials (CMs) are recommended as attractively active materials due to their diverse nanostructures and unique electron transport pathways, demonstrating great potential for highly efficient energy storage applications, electrocatalysis, and beyond. Among these newly reported CMs, metal-organic framework (MOF)-derived CMs have achieved impressive development momentum based on their high specific surface areas, tunable porosity, and flexible structural-functional integration. However, obstacles regarding the integrity of porous structures, the complexity of preparation processes, and the precise control of active components hinder the regulation of precise interface engineering in CMs.
