Healing and Health Perspectives of Nanocoatings for Medicinal Applications

Introduction

Nanotechnology, a pioneering scientific field, is at the forefront of manipulating and engineering materials and devices at the nanoscale, a dimension where structures with unprecedented properties and functions emerge. This profound manipulation of matter has unleashed a transformative era of innovation in the realm of healthcare, a domain previously unimagined in its possibilities (Erdonmez et al., 2014; Meda et al., 2022; Rastogi et al., 2022). One of the most striking and celebrated applications of nanotechnology in medicine is its role in drug delivery. At the heart of this innovation lies nanoparticles, minuscule in size but monumental in their impact. Their tiny dimensions, combined with an expansive surface area, have bestowed upon them invaluable characteristics in the world of medical science. These characteristics have revolutionized the way drugs are administered and targeted within the human body, heralding a new era of precision medicine. Nanoparticles serve as remarkable vehicles for drug delivery, ensuring the precise loading and subsequent targeted release of therapeutic compounds to specific disease sites within the body. This level of precision is a paradigm shift in healthcare (Chaudhary et al., 2023; Saini et al., 2023). Traditional drug delivery methods often result in the dispersion of medications throughout the body, causing collateral damage to healthy tissues and, consequently, a range of undesirable side effects. In stark contrast, nanotechnology's drug delivery approach, facilitated by nanoparticles, minimizes these unintended consequences. The implications of this innovation are far-reaching. In the field of cancer treatment, for instance, the use of nanoparticles in drug delivery allows for the precise targeting of chemotherapy agents to cancerous cells while sparing healthy tissues. The result is not just more effective treatment overall but also a notable decrease in the crippling side effects of chemotherapy that are often experienced, like nausea and loss of hair.

Beyond oncology, nanotechnology's precision drug delivery holds immense potential for managing chronic diseases, from diabetes to heart conditions. The ability to precisely administer medications, regulating their release over time, allows for more stable and effective therapies. This, in turn, enhances patient well-being and quality of life. In addition to its groundbreaking applications in precision drug delivery, nanotechnology has also catalysed transformative changes in the realms of diagnostic tools and regenerative medicine, further enhancing the scope of its impact on healthcare (Akbari-Alavijeh et al., 2020; Mohammadi et al., 2018; Zhao et al., 2023). Concurrently, the chapter emphasizes the multifaceted potential of nanocoating in medical applications. The influence of nanotechnology on diagnostics and medical imaging is particularly noteworthy. The development of nanoscale contrast agents and sensors has elevated healthcare professionals' ability to gain unparalleled insights into the human body. These cutting-edge tools empower early disease detection, continuous health monitoring, and more accurate diagnoses, ushering in a paradigm shift in how diseases are identified and managed. For instance, the usage of nanoscale contrast agents in magnetic resonance imaging (MRI) provides enhanced clarity in identifying subtle abnormalities, significantly improving the diagnostic process (Keshtmand et al., 2023).
