ABSTRACT
Small things have a big impact and so does the field of nanotechnology, because greatness is never determined by its size. Almost every dimension of survival; from security to medicine nowadays is dominated by nanotechnology. The nano-world is blooming rapidly in recent years and like other medical fields it has till date transmuted the sphere of dentistry in a huge way. Periodontitis refers tothe inflammation of the gums and supporting tissues of the tooth. With its progress in various fields, nanotechnology has also evolved as a promising mode of treatment of periodontitis. Nanotechnological methods involve utilization of nano-materials, nano-biotechnology and nano-robots for the treatment and aftercare of periodontal health. This paper focuses on the possible applications of nanotechnology towards periodontics.
ABSTRACT
Oncologists all over the globe, relentlessly research on methodologies for detection of cancer and precise localization of cancer therapeutics with minimal adverse effects on healthy tissues. Since the previous decade, the fast growing research in nanotechnology has shown promising possibilities for achieving this dream of every oncologist.Nanorobots (or nanobots) are typical devices ranging in size from 0.1 to 10 μm and constructed of nanoscale or molecular components. Robots will augment the surgeon’s motor performance, diagnostic capability and sensations with haptics and augmented reality. The article here aims in briefly describing the architecture of the nanorobots and their role in oncotherapy. Although, research into nanorobots is still in its preliminary stages, the promise of such technology is endless.
ABSTRACT
Molecular nanotechnology has been defined as the three-dimensional positional control of molecular structure to create materials and devices to molecular precision. The human body is comprised of molecules; hence the availability of molecular nanotechnology will permit dramatic progress in human medical services. More than just an extension of "molecular medicine," nanomedicine will employ molecular machine systems to address medical problems, and will use molecular knowledge to maintain and improve human health at the molecular scale. Nanomedicine will have extraordinary and far-reaching implications for the medical profession, for the definition of disease, for the diagnosis and treatment of medical conditions including aging, and ultimately for the improvement and extension of natural human biological structure and function. Nanomedicine is the preservation and improvement of human health using molecular tools and molecular knowledge of the human body. Nanomedicines are an emerging group of therapeutics that take advantage of our understanding of phenomena on the nanometer scale. Nanomedicines research requires expertise in a range of diverse fields and thus requires multidisciplinary teams. This article presents a brief review of Nanomedicines with an emphasis on its various aspects associated i.e. introduction, definition, medical and clinical uses, especially role of nanomedicines in treatment of dreadful disease like cancer in current scenario. The article also reveals the concept of nanorobots as well as implications for nanotoxicology from nanomedicines.
