Hollow structures have demonstrated great potential in drug delivery owing to their privileged structure, such as high surface-to-volume ratio, low density, large cavities, and hierarchical pores. In this review, we provide a comprehensive overview of hollow structured materials applied in targeting recognition, smart response, and drug release, and we have addressed the possible chemical factors and reactions in these three processes. The advantages of hollow nanostructures are summarized as follows: hollow cavity contributes to large loading capacity; a tailored structure helps controllable drug release; variable compounds adapt to flexible application; surface modification facilitates smart responsive release. Especially, because the multiple physical barriers and chemical interactions can be induced by multishells, hollow multishelled structure is considered as a promising material with unique loading and releasing properties. Finally, we conclude this review with some perspectives on the future research and development of the hollow structures as drug carriers.

“… 50 High surface area with the porous architecture of MSN is advantageous since the pore reservoirs could act for the analyte diffusion into the pores, which are decorated with bio-recognition elements via silanol functional groups. 81 Since the increasing pore wall thickness directly affects the maximum binding analyte amount, it is an important parameter for porous structures. 82 Silanol functional groups allow the design of different bio-recognition strategies and improve the accuracy of detection while providing time-efficient detection methods.…”

Public awareness of infectious diseases has increased in recent months, not only due to the current COVID-19 outbreak but also because of antimicrobial resistance (AMR) being declared a top-10 global health threat by the World Health Organization (WHO) in 2019. These global issues have spiked the realization that new and more efficient methods and approaches are urgently required to efficiently combat and overcome the failures in the diagnosis and therapy of infectious disease. This holds true not only for current diseases, but we should also have enough readiness to fight the unforeseen diseases so as to avoid future pandemics. A paradigm shift is needed, not only in infection treatment, but also diagnostic practices, to overcome the potential failures associated with early diagnosis stages, leading to unnecessary and inefficient treatments, while simultaneously promoting AMR. With the development of nanotechnology, nanomaterials fabricated as multifunctional nano-platforms for antibacterial therapeutics, diagnostics, or both (known as “theranostics”) have attracted increasing attention. In the research field of nanomedicine, mesoporous silica nanoparticles (MSN) with a tailored structure, large surface area, high loading capacity, abundant chemical versatility, and acceptable biocompatibility, have shown great potential to integrate the desired functions for diagnosis of bacterial infections. The focus of this review is to present the advances in mesoporous materials in the form of nanoparticles (NPs) or composites that can easily and flexibly accommodate dual or multifunctional capabilities of separation, identification and tracking performed during the diagnosis of infectious diseases together with the inspiring NP designs in diagnosis of bacterial infections.

“…Constructed from metal ions or metal-containing clusters and organic linkers, these porous materials exhibit many superior properties over classical nano-and mesoporous materials such as zeolites, amorphous carbon, and mesoporous silica [1,2] with tunable pore size, tailorable composition and structure, well-defined pore aperture, versatile functionality and high guest loading efficiency. [3] Consequently, MOFs have shown great potential in molecular storage, [4] heterogeneous catalysis, [5] biopharmaceutical delivery, [6,7] gas separations [8] and energy storage applications.…”

Biocatalytic metal-organic framework (MOF) composites, synthesized by interfacing MOFs with biocatalytic components, possess the unprecedented synergetic properties that is hard to achieve by the conventional strategies, represents one of the next-generation composite materials for diverse biotechnological applications. Until now , research on the applications of biocatalytic MOFs is still in its preliminary stage, with a wide variety of studies being focusing on the bioprotection role of MOFs. However, their diversity of building units, molecular-scale tunability, modular synthetic routes, and more detailed understanding of the heterogeneous MOF-biointerface could even lead to completely new applications and potentials beyond our current imagination. The most recent rapid advanced progress in biocatalytic MOFs present ground-breaking applications in smart and tunable biocatalysis, precision nanomedicine, vaccine and gene delivery, biosensing and nano-biohybrids. Herein, the general and advanced synthesis strategies for improving the materials properties of biocatalytic MOFs, from tuning biocatalytic activity to framework stability to synergistic properties with other materials, are summarized. Then, the latest state-of-the-art applications of the biocatalytic MOF systems and recent advanced developments that are shaping this emerging field are surveyed. Finally, to define promising research directions, a critical evaluation and future prospects for the potential applications of biocatalytic MOFs are provided.
