Introduction

The convergence of nanotechnology and clinical medicine is revolutionizing healthcare, offering innovative solutions for diagnosis, treatment, and monitoring of various diseases [1-3]. This review explores the advancements in translational nanotechnology, specifically focusing on its impact on imaging modalities and surgical interventions. By leveraging the unique properties of nanomaterials, researchers and clinicians are developing more precise, effective, and less invasive methods for managing complex medical conditions [4-6]. The goal is to bridge the gap between laboratory discoveries and clinical practice, ultimately enhancing patient outcomes.

In imaging, nanomaterials offer tailored solutions that significantly improve the resolution, contrast, and target efficiency of diagnostic techniques [7, 8]. Their unique physicochemical properties-such as high surface-area-to-volume ratios, tunable optical behavior, and magnetic responsiveness-enable more accurate visualization of pathologies, particularly in oncology and cardiovascular medicine [9- 11]. Nanoparticle-based contrast agents are now being designed not only to enhance conventional modalities like MRI, CT, and positron emission tomography (PET) but also to facilitate emerging techniques such as photoacoustic and near-infrared (NIR) fluorescence imaging [12-14]. Moreover, the advent of multifunctional and theranostic nanoparticles has expanded the role of imaging from mere visualization to simultaneous diagnosis and treatment monitoring, representing a paradigm shift in clinical diagnostics [15-17].

In parallel, surgical practice is undergoing a transformation driven by nanotechnology’s role in enhancing intraoperative precision and postoperative outcomes [18, 19]. Nanoparticles, engineered for image-guided surgery, enable real-time tumor delineation, thereby minimizing residual disease and preserving healthy tissue [20, 21]. Additionally, persistent luminescent and environment-responsive nanoparticles allow for deeper tissue visualization and sharper margin definition, especially in minimally invasive procedures [22]. These innovations contribute not only to improved resection accuracy but also to reduced complications, shorter recovery times, and better longterm prognosis for patients undergoing complex surgeries [23, 24].

Despite these promising developments, challenges remain in translating nanotechnological advances into routine clinical use. Issues such as biocompatibility, scalability, regulatory approval, and long-term safety continue to hinder widespread adoption [25, 26]. Nevertheless, ongoing interdisciplinary collaboration among materials scientists, clinicians, and regulatory bodies is accelerating the pace of innovation. As clinical trials advance and regulatory frameworks evolve, nanotechnology is poised to become an integral component of modern medicine, offering transformative solutions in both diagnostics and therapeutics [27, 28].
