Nanomedicine: application areas and development prospects (original) (raw)

Nanotechnology to Revolutionize Medicine

Journal of Drug Delivery and Therapeutics, 2012

One of the most promising technologies of 21 st century is nanotechnology. Nanotechnology is a collective term referring to technological developments on the nanometer scale, usually 0.1-100 nm. A nanometer is one-billionth of a meter, too small to be seen with a conventional laboratory microscope. It is at this size scale-about 100 nanometers or less-that biological molecules and structures inside living cells operate. Therefore, nanotechnology is engineering and manufacturing at the molecular scale. Nanomedicine is new concept in combining nanotechnology and medicine. Nanotherapeutics is the use of nanomedicine in therapy. The definition of nanomedicine requires attention as the nanotechnology represents a cluster of technologies. Nanomedicine, an offshoot of nanotechnology, refers to highly specific medical intervention at the molecular scale for curing disease or repairing damaged tissues, such as bone, muscle, or nerve Utilities of nanotechnology to biomedical sciences implies creation of materials and devices designed to interact with the body at sub-cellular scales with a high degree of specificity. This could be potentially translated into targeted cellular and tissue-specific clinical applications aimed at maximal therapeutic effect with very limited adverse-effects. Nanomedicine can offer impressive resolutions for various life threatening diseases. Disease areas which can be expected to benefit most from nanotechnology within the next few years are cancer, diseases of the cardiovascular system, the lungs, blood, neurodegenerative diseases, diabetes, inflammatory/infectious diseases, and orthopaedic problems. This article presents an overview of some of the applications of nanotechnology in nanomedicine.

Growing interest in the future medical applications of nanotechnology is leading to the emergence of a new field called nanomedicine. Nanomedicine needs to overcome the challenges for its application, to improve the understanding of pathophysiologic basis of disease, bring more sophisticated diagnostic opportunities, and yield more effective therapies and preventive properties. Nanotechnology involves manipulating properties and structures at the nanoscale, often involving dimensions that are just tiny fractions of the width of a human hair. Nanotechnology is already being used in products in its passive form, such as cosmetics and sunscreens, and it is expected that in the coming decades, new phases of products, such as better batteries and improved electronics equipment, will be developed and have far-reaching implications.

Nanomedicine-Challenge and Perspectives

Angewandte Chemie International Edition, 2009

Nanomedicine introduces nanotechnology concepts into medicine and thus joins two large cross disciplinary fields with an unprecedented societal and economical potential arising from the natural combination of specific achievements in the respective fields. The common basis evolves from the molecular scale properties relevant in the two fields. Nanoanalytical tools such as local probes and molecular imaging techniques, allow us to characterize surface and interface properties at a nanometer scale at predefined locations, while elaborated chemical approaches offer the opportunity for the control and addressing of surfaces e. g. for targeted drug delivery, enhanced biocompatibility and neuroprosthetic purposes. This commonality opens a wide variety of economic fields both of industrial and clinical interests. However, concerns arise in this cross disciplinary area about toxicological aspects and ethical implications. This review gives an overview of selected recent developments of nanotechnology applied on medical objectives.

Emerging trends of nanomedicine - an overview

Fundamental & Clinical Pharmacology, 2009

Nanotechnology is an emerging branch of science that deals with designing tools and devices of size 1-100 nm with unique function at the cellular, atomic and molecular levels [1]. Nanoparticles of size <100 nm possess novel optical, electronic and structural properties not seen with macro molecules [2]. The concept of using nanotechnology in medical research and clinical practice is known as nanomedicine. This idea was first voiced by the eminent Nobel Laureate Richard Feynman that tiny nanorobots and nanodevices could be used to provide more accurate, reliable, cost effective and faster approaches in diagnosis and treatment [3]. Nanoparticles are smaller than human cells but similar in size to biological macromolecules like enzymes and receptors [1]. They can be used as probes by conjugating them to peptides, antibodies and nucleic acids to detect cellular movements and molecular changes associated with pathological states. Such probes

Nanomedicine: Overview, Problem, Solution and Future

Over the years the field of nanotechnology has gained tremendous ground, it has really begun developing into more progressive forms in medical research. It is expected that nanotechnology can have an vast optimistic impact on human health. Pertinent processes of living organisms take place essentially at nanoscale, basic biological divisions like DNA, proteins or cell membranes are of this aspect Nanomedicine benefits greatly from expansions in nanotechnology and because of this a wide variety of medicines and medical procedures have become accessible predicting that the future holds more advancement in this field. Mononuclear phagocytes, dendritic cells, endothelial cells, and cancers (tumor cells, as well as tumor neovasculature) are key targets. The use of nanoscale technology in medicine is one of the latest and most exhilarating forms of science that is still in its infancy. From the name, it is obvious that nanotechnology focuses on very small things including atoms and molecular objects. The assumption is that once we know the littlest parts of life we will have the capacity to comprehend everything that is going on the globe, yet it has been involved towards enhancing mechanical development and, sadly, the potential dangers of nanomedicine have remained inadequately evaluated. Research into the balanced delivery and targeting of pharmaceutical, medical, and diagnostic agents is at the front line of projects in nanomedicine. These involve the recognition of the cells and receptor connected to precise medical circumstances and selection of the suitable nanocarriers to attain the necessary responses while minimizing the side effects. The prospective and the dangers of nanomedicine need to be amenably researched, analyzed, disputed and delimited. This paper is focused on the problems, precautions, as well as the future of nanomedicine. However, it is important to note that nanotechnology also raises important social issues and ethical challenges. Proponents suggest that a nanomedicine-enabled " revolution " will bring far-reaching changes to economic, social and environmental relations. Yet to date, there has been a shortage of life-threatening discussion about civic interest issues associated with the predicted nanomedicine " revolution " and in specific what role civil society should have in decision making. This research was conducted using information provided by textbooks on nanomedicine, nanotechnology journals and books, journals on how nanotechnology in medicine work and its history and web pages about nanotechnology and nanomedicine.
