Abstract
Background: Osteoporosis is a disease characterized by progressive bone loss due to aging and menopause in women leading to bone fragility with increased susceptibility towards fractures. The silent disease weakens the bone by altering its microstructure and mass. Therapy is based on either promoting strength (via osteoblast action) or preventing disease (via osteoclast action). Current therapy with different drugs belonging to antiresorptive, anabolic and hormonal classification suffers from poor pharmacokinetic and pharmacodynamic profile.
Objectives: Nanoparticles provide breakthrough as an alternative therapeutic carrier and biomedical imaging tool in bone diseases. The current review highlights bone physiology and pathology along with potential applications of nanoparticles in osteoporosis through use of organic and inorganic particles for drug delivery, biomedical imaging as well as bone tissue regeneration therapy.
Results: Inorganic nanoparticles of gold, cerium, platinum and silica have effects on osteoblastic and osteoclastic lineage. Labelling and tracking of bone cells by quantum dots and gold nanoparticles are advanced and non-invasive techniques. Incorporation of nanoparticles into the scaffolds is a more recent technique for improving mechanical strength as well as regeneration during bone grafting.
Conclusions: Promising results by in vitro and in vivo studies depicts effects of nanoparticles on biochemical markers and biomechanical parameters during osteoporosis suggesting the bright future of nanoparticles in bone applications. Any therapy which improves the drug profile and delivery to bone tissue will be promising approach. Superparamagnetic, gold, mesoporous silica nanoparticles and quantum dots provide golden opportunities for biomedical imaging by replacing the traditional invasive radionuclide techniques.
Keywords: Bone regeneration, drug delivery, metallic NPs, nanoparticles, nanotechnology, osteoporosis.

Advancements in Robotic and AI-based Drug Discovery and Delivery for Neurological Disorders
Neurological disorders, including Alzheimer's disease, Parkinson's disease, epilepsy, and brain tumors, pose significant challenges in drug delivery due to the blood-brain barrier's intricate structure and the complexity of neuronal networks. Traditional drug delivery methods often fall short in reaching therapeutic concentrations within the central nervous system, limiting treatment efficacy and ...read more
Electrospun Fibers as Drug Delivery Systems
In recent years, electrospun fibers have attracted considerable attention as potential platforms for drug delivery due to their distinctive properties and adaptability. These fibers feature a notable surface area-to-volume ratio and can be intentionally designed with high porosity, facilitating an increased capacity for drug loading and rendering them suitable for ...read more
Nanoemulsions in cancer therapy
Solid tumors are characterized by leaky vascular structure, defective angiogenesis and high interstitial fluid load, providing opportunities for nanoparticles to preferentially exudate and be retained in tumors. This phenomenon is commonly referred to as the enhanced permeability and retention (EPR) effect, which is considered to be an important reason why ...read more
Nanotechnology Based Chemotherapy for the treatment of Head & Neck Cancer
The escalating recurrence rates observed in Head and Neck cancer, particularly within the chemo-therapeutically treated cohort (50-60%), can be attributed to the non-selective nature of current anticancer drug delivery modalities. In this context, nanotechnology-based drug delivery systems emerge as a promising avenue for achieving precise localization of therapeutic agents to ...read more
