Upcoming Impression of Nanotechnology in Therapeutic Medicine

Science and technology at the nanoscale is acting as an important key to unlock many biological riddles that would have been unyielding a few years ago. Recently, silicon chip technology has emerged as the ability to manufacture at 100 nm and below, and microscopes that allow us not only to ‘see’ but to manipulate atoms and molecules have facilitated at the commence of the 21st century into the thick revolution of life sciences. Nanotechnology has matured into a dominant focus of research and development activities in the preceding two decades. Nanotechnology and nanomedicine are considered as complementary disciplines, aiming for better human life. Applications of nanotechnology to medicine and physiology consist of materials and devices, which are designed to interact with the body at molecular scale with a high degree of specificity. This finally results in their potential use into targeted cellular and tissue-specific clinical applications and helps in achieving maximal therapeutic efficacy with minimal side effects. Currently, nanotechnology and nanoscience are aiming particularly to design and formulate a platform to expand the market for many drugs and forming a basis of high profit to industry. Thus, in the present scenario, nanotechnology is proving beneficial in solving problems in different fields of medicine. In this paper, we will highlight and discuss the potential use of nanotechnology in clinical applications.

Emergent Intrusion of Nanotechnology and Nanotoxicology in Reproductive Biology

In the last decade, nanotechnology has been extensively introduced for biomedical applications opening a new hope in medicine as well as in other sciences. In this review article an emerging use of nanotechnology in reproductive medicine and reproductive biology has been described. Nanoparticles being of small sizes has rather more advantages and therefore are more preferred nanotechnological tool. They are successfully used for the treatment and imaging of reproductive system-related cancers. Contrarily, increased application of nanomaterials and nanotechnology and their exposure has become a critical issue raising the concerns about their potential toxicity. It is therefore indicated that the nanobased methods are innovative but at the same time potentially controversial approaches. Exposure of females to such toxicity may lead to fatal impacts on both female reproductivity and fetal development. Thus, in the present paper, we will highlight and discuss the nanotoxic effects of nano materials on human reproductive biology.

Nanotechnology –A Novel Science Revolutionising the Field of Medicine

Nanotechnology involves manipulating properties and structures at the nanoscale, often involving dimensions that are just tiny fractions of the width of a human hair. Its application as products in its passive form, such as cosmetics and sunscreens are already in an active stage, and some more new phases of products are expected in the coming decades. The use of nanotechnology in medicine offers some exciting possibilities providing great benefits for society in the future. Some techniques are only imagined, whereas others are at various stages of testing. This emerging technology is already being used as the basis for new, more effective drug delivery systems and is in early stage development as scaffolding in nerve regeneration research. Moreover, the National Cancer Institute has created the Alliance for Nanotechnology in Cancer in the hope that investments in this branch of nanomedicine could lead to breakthroughs in terms of detecting, diagnosing and treating various forms of cancer. This review discusses the various platforms of nanotechnology being used in different aspects of medicine.

Inconsistent Impact of Nanoparticles on Food Chain

Nanotechnology has proved to be beneficial for its medical, ethical, mental, legal and environmental applications. It encompasses several fields, e.g., engineering, biology, chemistry, computing, material science, military applications and communications. The incumbent technology identifies unique properties of materials with dimension in the range of 1–100 nm. Though these properties yield many far-reaching societal benefits in several fields, including improved manufacturing methods, water purification systems, energy systems, physical enhancement, nanomedicine, better food production methods and nutrition, and large-scale infrastructure auto-fabrication, but they may also pose threat and risks to environment and human health demanding great concern for safety issues. To lessen the deleterious impacts of nanoparticles (NPs) on environment, especially on the food chain, it is imperative to develop potential toxicity tests, which would aid in the rapid detection of the lethal effects of NPs (screening) and epidemiologic studies must be conducted on exposed populations. The uptake, bioaccumulation, biotransformation and risks of nanomaterials (NMs) for the food crops are still unclear. Very few reports exist that provide the in-depth information regarding interaction of NMs and plant species, largely at the very early growth stages of the plants.
