    Catalytic and biomedical applications of nanocelluloses: A review of recent developments
    (Elsevier B.V., 2024) Khorsandi, D.; Jenson, S.; Zarepour, A.; Khosravi, A.; Rabiee, N.; Iravani, S.; Zarrabi A.
    Nanocelluloses exhibit immense potential in catalytic and biomedical applications. Their unique properties, biocompatibility, and versatility make them valuable in various industries, contributing to advancements in environmental sustainability, catalysis, energy conversion, drug delivery, tissue engineering, biosensing/imaging, and wound healing/dressings. Nanocellulose-based catalysts can efficiently remove pollutants from contaminated environments, contributing to sustainable and cleaner ecosystems. These materials can also be utilized as drug carriers, enabling targeted and controlled drug release. Their high surface area allows for efficient loading of therapeutic agents, while their biodegradability ensures safer and gradual release within the body. These targeted drug delivery systems enhance the efficacy of treatments and minimizes side effects. Moreover, nanocelluloses can serve as scaffolds in tissue engineering due to their structural integrity and biocompatibility. They provide a three-dimensional framework for cell growth and tissue regeneration, promoting the development of functional and biologically relevant tissues. Nanocellulose-based dressings have shown great promise in wound healing and dressings. Their ability to absorb exudates, maintain a moist environment, and promote cell proliferation and migration accelerates the wound healing process. Herein, the recent advancements pertaining to the catalytic and biomedical applications of nanocelluloses and their composites are deliberated, focusing on important challenges, advantages, limitations, and future prospects. © 2024 The Authors

    Inspired by nature: Bioinspired and biomimetic photocatalysts for biomedical applications
    (KeAi Communications Co., 2024) Bigham, A.; Zarepour, A.; Safarkhani, M.; Huh, Y.; Khosravi, A.; Rabiee, N.; Iravani S.
    The field of photocatalysis has witnessed a significant advancement in the development of bioinspired and biomimetic photocatalysts for various biomedical applications, including drug delivery, tissue engineering, cancer therapy, and bioimaging. Nature has evolved efficient light-harvesting systems and energy conversion mechanisms, which serve as a benchmark for researchers. However, reproducing such complexity and harnessing it for biomedical applications is a daunting task. It requires a comprehensive understanding of the underlying biological processes and the ability to replicate them synthetically. By utilizing light energy, these photocatalysts can trigger specific chemical reactions, leading to targeted drug release, enhanced tissue regeneration, and precise imaging of biological structures. In this context, addressing the stability, long-term performance, scalability, and cost-effectiveness of these materials is crucial for their widespread implementation in biomedical applications. While challenges such as complexity and stability persist, their advantages such as targeted drug delivery and personalized medicine make them a fascinating area of research. The purpose of this review is to provide a comprehensive analysis and evaluation of existing research, highlighting the advancements, current challenges, advantages, limitations, and future prospects of bioinspired and biomimetic photocatalysts in biomedicine. © 2024 Chongqing University

    (Elsevier B.V., 2024) Iravani, S.; Zare, E.N.; Zarrabi, A.; Khosravi, A.; Makvandi, P.
    MXene/zeolitic imidazolate framework (ZIF) composites represent a rapidly growing area of research in the field of energy storage, catalysis, sensing, flexible electronics, microwave/electromagnetic wave absorption, biomedicine, and environmental remediation/water treatment. The integration of MXene and ZIFs in composite materials has led to develop highly sensitive and selective (bio)sensing platforms, enabling advances in biomedicine/healthcare, environmental monitoring, and industrial safety. MXene/ZIF composites showcase exceptional catalytic activity for a wide range of chemical transformations. Their exceptional adsorption capacity, selectivity, membrane integration, regeneration capabilities, and antibacterial properties make them invaluable assets in tackling water treatment challenges. The combination of MXene's conductivity and ZIF's dielectric properties, along with their unique morphological features, results in enhanced microwave absorption capabilities. Furthermore, while the biomedical applications of MXene/ZIF composites are still in the early stages of exploration, the combination of their unique properties provides a platform for innovative solutions in drug delivery, cancer nanotheranostics, bioimaging, tissue engineering, and biosensing. This article aims to present a comprehensive overview of the research progress in MXene/ZIF composites, focusing on current trends, important challenges, and future perspectives. © 2024 Elsevier B.V.
