Special Issue Information

Dear Colleagues,

With the intensification of global population aging, the prevalence of bone diseases among middle-aged and elderly individuals worldwide remains significantly high. The development of advanced nano-biomaterials and novel pharmacological treatments to effectively treat various bone diseases, including osteoporosis, osteoarthritis, and osteoporotic fractures, presents a substantial challenge for contemporary osteopathology research. Through comprehensive investigations into the molecular and cellular mechanisms underlying bone diseases, the development of targeted therapeutics and advanced drug delivery platforms has emerged as a novel paradigm in the treatment of these conditions. Nanomedicine delivery systems have been extensively utilized within this field, exhibiting exceptional performance. The design and therapeutic application of these delivery systems are advancing rapidly, encompassing areas such as nanomedicine carriers, delivery mechanisms, safety and efficacy evaluations, and the clinical application of nanomedicine materials. Despite ongoing advancements in research, the nano-based drug delivery system continues to encounter numerous challenges within the emerging field of intelligent medicine. Key issues that require further investigation include the biocompatibility, stability, and immune response of drug carriers. Additionally, the therapeutic efficacy of these delivery systems must be rigorously evaluated in vivo or ex vivo to ensure their suitability for future clinical applications.

This Special Issue will cover all the advances, challenges, and future perspectives in using nano-based drug delivery system to manage bone diseases (e.g., osteoporosis, osteoarthritis, fracture defect, bone tumors, etc.). Original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Research, policy, and trends related to the design of nanobiomedical materials and the therapeutic application of bone diseases.
  • Stimuli-responsive nano-biomedical materials functioning as drug carriers in bone disease.
  • Nano-drugs or nanocarriers in pharmacy of bone diseases, including polymer drug carriers, drug release, targeted therapy, and drug metabolism.
  • Bone disease therapeutic nano-biomaterials facilitating efficient delivery of therapeutic agents such as drugs, genes, and proteins.
  • Biopolymers, nanocomposites, nano micelles, polymersomes, and liposomes employed as drugs or drug carriers for bone disease therapy.

We look forward to receiving your contributions.

Bone metastases are a prevalent and debilitating consequence of various cancers, including breast and prostate carcinomas, which significantly compromise patient quality of life due to pain, fractures, and other skeletal-related events (SREs). This review examines the pathophysiology of bone metastases, emphasizing the role of the bone microenvironment in tumor progression through mechanisms such as osteotropism and the dysregulated bone remodeling cycle. The primary focus is on the emerging nano-drug delivery systems (DDS) designed to target the bone microenvironment and improve the therapeutic index of anticancer agents. Current treatments, mainly comprising bisphosphonates and radiotherapy, provide palliative benefits but often have limited efficacy and significant side effects. Innovative strategies, such as bisphosphonate-conjugated nanoparticles and targeted therapies that utilize the unique bone marrow niche, are explored for their potential to enhance drug accumulation at metastatic sites while minimizing systemic toxicity. These approaches include the use of liposomes, polymeric nanoparticles, and inorganic nanoparticles, which can be functionalized to exploit the biological barriers within the bone microenvironment. This review also discusses the challenges and future directions for nano-DDS in clinical settings, emphasizing the need for multidisciplinary research to effectively integrate these technologies into standard care protocols.

The application of light-responsive nanomaterials (LRNs) in bone tissue engineering shows broad prospects, especially in promoting bone healing and regeneration. With a deeper understanding of the mechanisms of bone defects and healing disorders, LRNs are receiving increasing attention due to their non-invasive, controllable, and efficient properties. These materials can regulate cellular biological reactions and promote bone cell adhesion, proliferation, and differentiation by absorbing specific wavelengths of light and converting them into physical and chemical signals. In addition, the unique surface morphology and biocompatibility of LRNs enable them to effectively load drugs in bone tissue engineering, achieve precise release, and optimize the bone regeneration process. Through photothermal and photodynamic therapy, these materials also possess antibacterial properties and can play an important role in the repair of infectious bone defects. Although LRNs have shown significant advantages in bone tissue regeneration, a series of challenges still need to be overcome to achieve their widespread and effective clinical applications. This article summarizes the basic principles, classification, and potential applications of LRNs in bone tissue regeneration, aiming to provide reference for future research and clinical applications.
